Please consider supporting me via Patreon: / thedroneracingengineer I'm getting a black screen in my FPV goggles. I'll take you through the troubleshoot.
you know what's hilarious is I had the same problem so I took my camera out put it back in and the problem was solved. so I guess you helped me fix it but neither of us know how lol.
just had the same issue! unplugged it a few times already. then while i was watching your video i was playing around with my multimeter and plugged it again. Then for some reason bingo i’ve got video ?
Mine was the a bad solder, ground decided to unsolder itself between the RunCam split and the FC. Pretty much had to remove the VTX and the RX to then even get a glimpse of the area. Was a complete pain in the butt although I really feel good knowing this noob can troubleshoot. Getting more and more confident every day. Appreciate the work you do JB!
I actually had this issue with a customer using that same setup. Replaced his board and same thing on new one. Turned out to be the camera exactly like what you found. Great video!
I was just investigating a similar problem. I got the OSD on the screen but image was grey. After some investigation I noticed, that the flight controller was outputting 0.5V on the 5V rail. So I tested the other 5V rails and there were multiple ones too low. However I found a functioning 5V output and tried that for the camera and it immediately worked. In your case it was likely to be the flight controller as well, because a) the camera gets it's power from there (I'm assuming) and b) this noise comes from the coils when there is something wrong with the switching frequency. This noise often occurs when the switching power supply is idling (and thus turning down the pwm signal into the audible frequency) - this is also why you mostly hear smartphone chargers humming when they are left hanging on the wall without charging a phone..
I asked you on a live streama few months back if OSD chips are interchangeable, you said yes and I've since confirmed it to be true......ordered a few blank chips and yes they work. I had a Diatone Mamba V1 on my Chameleon that lost OSD. I put in a Foxeer Razer for the OSD as opposed to swap the FC. Then the chips arrived and I changed it out on the FC......still no joy. The Razer camera accidentally shorted and went black which forced me to troubleshoot all. Found a microscop[ic solder ball on the FC. Isopropyl bath and all is well. Video, OSD, and A new Ratel.
I had an issue with a black camera on my Eachine wizard after i re-mounted it in the quad after a hard crash. The screws I was using to mount it were just the exactly correct size to just barely touch the board inside of the camera case just slightly. What I was seeing in this case was that I would arm the quad and the camera was visible but as soon as I moved the throttle up slightly the video would go black. I discovered this by removing the screws from the camera altogether and testing again. Check the tightness of your side-mounting screws on the camera inside to make sure they are not touching the board perhaps? I even added a small strip of electrical tape inside of where those screws were to make sure they didn't touch again as well as adding a nylon washer.
Thank you, I have same issue today and this solved my issue. I had my wizard x220hv completely rebuilt with just the frame and motors are from the original. I'm using a newer foxeer camera and it was all fine in the past two years withstand many crashes until today I discovered one of the side mount screw was lost and the video got a bit shaky and jelly-like, so I decided to tighten the other side screw then I was getting exactly the same issue you described, the quad lifted in the mid air and screen all black. Tried best to land it and damaged a GPS module 🤷♂️.
I have had kind of the same problem. I had a screw barely touching the motors windings where they come out of the motor. When my top plate was mounted with the SMA connector touching the carbon, it was backfeeding the voltage from the motors into the antenna ground and wreaking all kinds of havok. Since you get a straight up black screen of death on the camera, I would check for any point that may be shorting out to the frame, and backfeeding into the antenna SMA.
I know the issue! Just spent 3 hours this past weekend rebuilding the quad from the ground up to finally figure the stupid problem... Your screws are grounding with the camera! I bet if you put it back together,you will get black vid again! But if you un-screw the camera, video will come back (NTSC NOT DETECTED)! WALA! Problem SOLVED!
I had the same issues with a couple Runcam Swifts. The mounting screws (the ones included with the cam) went a little too deep inside and were just barely coming into contact with the SMD caps on the edge of the board. This caused me a ton of frustration due to seemingly random camera blackouts until I discovered the source of the problem.
Tim Spitz after a crash my eagle has black screen but opened cam up and made sure all boards haven't separated but lens looks like it's slightly bent (as if cross threaded )so could it be the lens being not square to the first board?? Not had the cam long
For those of you reading this in the future. I also had the same exact problem. This guy is correct it is the screws. You will know it is because if you disconnect your camera and reconnect it lose it will show you video again. Then mount it and you get the blackness but still see the osd. Take out your screws filed them down with 600 sand paper, or a file. reassemble and your good to go. Thank you dex FPV.
could always do for the old standby of a couple of chilling cycles (spray can cooler) targeted at the FC and PDB then retesting. if the surface mount soldering iron a component is tired and emotional this usually gets it to make itself known.
Perfect timing for this video. I ejected my Runcam Eagle while flying today and now have a black screen with working OSD. Since the crash was hard enough for the screws to take chunks out of the camera case and rip the wires out of the connector, I'm going to guess (hope) that it just broke a solder joint on the PDB and didn't kill my new camera.
So Funny!!! I just finished fixing this same problem. Black Screen situation. And then I sit down to watch videos and this was the first one up. After trouble shooting everything, I discovered a short in the middle of a ground wire between the osd connection on the flight controller and the video transmitter. I saw a kink in the wire, and discovered no continuity in the wire, it was broke. Changed the wire and good to go.
Nice video...had the exact same problem black screen (minus the humming) just abt two weeks ago. It turns out the pdb pads powering the camera was faulty...i moved the wires and powered them from the pads that the vtx was powered from and it worked fine...until i crashed and broke my quad :)
What about an issue where the video signal and OSD is fine sitting idle on the bench, but as soon as you throttle up, the video signal cuts to grey but OSD is still fine.
@@JoshuaBardwell oh interesting! It's a brand new Mobula 6 too. 🙄 Guess It's time to resolder the camera...🤷♂️ Haha thanks for the response man, I appreciate it! Keep up the great work!
Interesting, I had the exact same symptom yesterday with my brand new Betaflight F3 FC. I unplugged the camera and reseated the plug and it was fine. Could there be a bad batch of FC's out there?
I had the same problem yesterday while setting up two mini quads. I am using Runcams 2, a FT951 25mW VTX and a AOMWAY 200mW VTX. While the first VTX doesn't send any voltage to a camera, the AOMWAY was sending 4.99V to the camera and nothing happened. The only way to solve this issue was to power the camera from the PDB, directly from the battery. I might have done some mistakes, I don't really know, but I spent 2 days trying to figure out what was wrong and the only working solution was this one...
Have used the auto scan. I did leave them in the van for a couple of days over winter in below zero conditions, it's been suggested that some moisture may if got inside and has knackered them. Had my new goggles delivered yesterday so I'm trying some trouble shooting myself. Iv also wired up a new eagle2pro so going over these conections to👍
I just heard a similar buzz/hum on a new build. It only sounded off for a few minutes before the PDB smoked. It really blows to have to disassemble a new build and start over with all the connections.
In my Setup the camera(caddx ratel) almost always works really well without a black screen. But sometimes theres no video but theres always osd. When I get a black screen and then unplug and plug the battery the video comes back. Why would that be?
We tend to discount the idea of the camera going bad, but they can be damaged from a hard impact dispite appearing physically undamaged. I recently had to replace TWO foxeer HS1177 cameras that looked totally fine, yet were doing a wierd black screen with glitchy green stripes. Just bad luck, I guess!
I have changed the camera for a brand new, let's see what happens!! BTW Joshua, Did you have problems soldering the GND pads on the Betaflighf3 FC??? All my GND (holes) and somes of the ESC signal couldn't be soldered properly
I love this video Josh!! I love your reaction when it ends up fixing itself. We explain the technology involved in this kind of repair as FM... or F#%king magic. I went through this for a couple weeks when I bought my premium, spared no expense, TBS Unify HV. Now it is finally behaving ( even though it's hooked up exactly the same way it always was when it wouldn't work right), and I just have to fly everyday... waiting for it to screw up again. Thanks Crappy!!
Hey Joshua! Im having this problem if my emax tinyhawk rtf kit. The other day my gogglea have a black screen and I have a signal shows the ch/Dr in the corner. Was about to take it apart and re so the wiring! Seeing id you could help me out
Seth Carmony me too yet I didn’t buy the rtf kit :/ I got the goggles and TinyHawk s and a frsky radio. I get a black screen and am unsure what to do because I don’t want to take it apart
When you plugged battery back in there was no camera so no/less load on inductor, then plugged camera in... Have you since plugged battery in with camera already plugged in yet? Im thinking it could be starting up with extra load on poor/dodgey/on-it's-limit inductor... I only ask as you didn't test again in video under 'exact' same circumstances as when fault was first happening & we all know how fickle eleaktrickery faults can be ;) Orr, could a weak connection somewhere induce such a noise from an inductor similar to (for example) a lose fluro tube does from its capacitor when they won't start up properly until connections are 'wriggles'? Sorry, you've likely covered this by now, just thinking out loud... Give it an extra hard rag'n & see what it does! :D
Mine was working fine till a hard landing, disconnected cam so i plug in and nada. BLACK SCREEN, OSD working copter is flyin but no video . I plugged ina nother cam & nothing so not sure yet
I had the same issue with my runcam and it turned out to be that the plug was not making 100% contact. However is was seated flush. I plugged it out and back in without any issues
I have been having this issue lately with one camera in particular. The camera was initially on one of my quads(call it X) which has a rrosd and i kept getting a black display in my goggles whereas if i connected the cam directly to a display monitor the cam would work perfectly fine. Then during a race this sunday i had to swap cameras between quad X with the cam issue to a race quad(call it Y). The cam displayed the same black screen issue on quad Y as well which has a HUBOSD on it. When i put another identical cam (i use the HS1177) on quad X i didnt notice this black screen issue anymore, hence i ruled out that the rrosd might be bad. Now coming to quad Y, i can get the image to appear by connecting and disconnecting the quad power supply 4-5 times and eventually the image pops up. Now i was skeptical to fly quad Y with such an issue but didnt notice any issue inflight (despite hitting gates etc and still the image didnt disappear ruling out a loose wiring i guess). So i think it is actually a cam issue cause it does work eventually when i plug the power in and out a couple of times till i see the image instead of a black screen. Not sure whats exactly wrong, maybe this particular camera board is more susceptible to power surge during lipo plug in on a quad due to some damaged internal component? Hope i was clear in what i was trying to say ;)
Devesh Sharma I have the same issue. Mine normally works but sometimes on power up it's a black screen. It usually fixes itself with just one or two power reboots.
Hello, i crashed my quad and the antena came off the vtx. I decided to solder and when removing the vtx I ripped off the plastic connector for (video, ground,Rx,5v).i did a horrible solder job and when power on drone little smoke came out and led lights are not working anymore . I ordered a new vtx .ordered the same one I had and just plugged everything in but vtx not turning on or the FC not recognizing it . Everything else seems to work .motors and everything. But not the lights not vtx. Could the FC be fry just in one part or when it does it does completely and nothing works . Please any answers will help .I'm struggling .
i get a black screen when i solder on smart audio but the osd from it is there, but than when i solder it differently i get the camera video but no smart audio.
Crashed my quad today in the sand at the park. Everything seems to be working fine except all I get is static on the video. I'm really new to this but I assume the VTX is bad which sucks because tall the solder connections are super tiny in this cinewoop.
BFF3 appears to have a weird issue for some. Same issue here: -VIDEO + OSD overlay worked for a few seconds. Afterwards, only OSD would work (black video) -Plugged in/out lipo a few times. No changes. -Wanted to record a video for FPVMODEL's support. Video + OSD works. Tried two different cameras and brand new unify race video transmitters. Did not change a single thing in the meantime (wiring). Same issue as described by CONRADM over at rcgroups.
I just recently had an experience where I got a black screen, so I figured it was an issue with the camera. So I swapped the camera, and still got a black screen. So I connected the original camera directly to VTX and then the VTX wouldn't turn on unless I disconnected the camera. So I swapped the VTX and wired everything back to the flight controller and still nothing lol so again I connected the new camera to the new VTX and then it finally worked. Turns out the VTX, camera, the CamS pad and the VTX S pads on the FC all stopped working at the same time after a crash. So I had to buy an entire new video system along with a flight controller.
wow i think this is whats happening to me i didn't crash jusst hard land kock loose the camera after plugging back in igot black screen. Tried another camera and still nothing
Obviously too late for me to comment on this but I had the very same thing and it turned out that the camera did not like having power off of the FC, when I hooked it up to an external transmitter while keeping it's single through the FC it worked fine! I hope this would be of any help!
my assumption is that it's your power supply you have a transistor that's about ready to go mosfet regulator I used to have the same problems with some of my ham radios I used to run when there's a spike usually he'll start to go bad try putting it under more of a load and see if you can get it to do it then like hook up a second camera good luck keep up the good videos
This happened to me when I replaced my VTX. Checked for shorts, tested camera and everything seemed fine. I go back to the wiring diagram for the VTX and realised I missed a bridge connection
My FPV camera shut off when I'm throttling only when the camera is recording in FHD at 60fps, it's not happening at 30fps or when not recording. black video with OSD. the camera is RunCam Split3 Lite, drone still flies while this happen. the FC is brand new (F4 ELRS AIO board), but then i checked that 1 motor is broken, still diagnosing..
Hey Josh I have a question I'm really kind of stuck. I put on for new motors on my quad copter which flowed perfectly fine before hand. When I put him on the motors were going in the wrong directions which made the copper go haywire on the bench. So then I reversed caveman style the wires and got the motors going in the right direction and it flew fine. But now my goggles my fat shark diversity only getting a gray screen I'm getting OSD but I'm not getting any video help
I have an issue with my camera and can't seem to find another example of it. There is what looks like horizontal white noise but goes away when I put my hand near the lense and when I take my hand away the white noise returns, can't figure this out🤔
Since it goes away when you touch the lens, it's probably grounding. A couple things to try are, 1) isolate the vTX SMA connector from the frame, and 2) make sure camera and vTX are grounded to the same place.
Still haven't figured out the problem. I really wish it wasn't just a fluke in your case. I just can't figure out what's going on. Cam works on other quad just fine, please help!
What about a black square almost completely covering the video feed? I saw the video on the edges then came back. I have it on DVR. I'm surprised I didn't crash it.
My problem is blank screen when powering the camera from the quad, but if I power directly from the battery everything works fine. Ive tested the quads power supply and the power lead im using is giving a healthy 12.14v so I dont get whats wrong.
This happened to me just today on a Mobulite6: camera (runcam atom) goes black while flying, osd stays. Camera comes back after a reboot. I'll try to change the camera and see if that fixes it, but given the symptoms I guess it won't
I'd try plugging in the battery a few times to see if I could replicate the issue and then trace the sound. It could be one of those things where something has a problem initialising sometimes but once it's on it's on.
I'm pretty sure its just a matter of plugging in the necassary cables; Red to + 5v black to ground, you should be able to use a usb cable, yellow to a RCA-video jack main plug and negative from usb on the shield
I just recieved a runcam and did a build with it. Everything runs fine as well as the osd. Ive got no humming noise. The solder joints are very nice. No bridging between joints.. Its an brand new runcam. I could try a different camera to see if it works, i suppose. Ita a Runcam Swift 2 and it never came with the old school aux. connectors. Blehhh ha
My camera blacked out a few times a one quad today. Of course it never did it on the bench, only after being in the air for 30-60 seconds. I guess I'll take it apart, check solder joints, wiggle some stuff, and put it back together. And see what happens. I saw the comment on grounding with the screws below but my camera is mounted on small TPU parts that came with an RDQ Mach One. So I don't think that's it.
Hello Mr.Bardwell,I was curious if you ever received your hglrc f3 v4 aio fc? I have mine in a x210 frame with a lumineer pod, it fits well but after setting the board up in bf, witch everything went without a hitch nut the maiden went way wrong!! Copter flipped over and out lol!! I kno you are super busy, just thought I would see where you were at with that board? I'm starting to think there's some serious issues with this board, especially now that the v5 just come out???!!! Anyhow, have a good one, and love what ya do!!! Jessie.K
hey Joshua Bardwell, love your channel I've learned alot thanks to u! I was wondering if you could explain the mechanism/chemistry within a lipo that effects c rating. Is it really all it's cracked up to be or is it just a lot of magic smoke and mirrors? Thanks again, keep up the good work
Mounting screw shorting inside the camera causing a lot of current draw on the regulator that is powering it. When the camera was pulled out that moved it just enough to get rid to the short? At least that is what happened to me with my 1177 but in was more permanent.
Hey dude I jus squires new copter. Straight newb. But uh ya the runcam2 has a floppy yellow wire is it pretty hard to solder it up also has brown epoxy do u know how to remove without ripping stuff apart to have clean solder area? Do u hav a vid doing this or?? Can u help guide a newb
I see that your camera actually works, but every time i've had black video, it has been because of a damaged camera circuit board. If i press on the board the video will work. This usually happens after a really hard hit to the camera and nothing seems to fix it.
Anyone, I use flight sight goggles and i forgot to one day unplug the battery and removed the receiver antennas. When i went out to fly again the next week, i noticed my goggles no longer show static, just black, i can move through the menu and everything. But when i broswer the frequencies i can only find one channel that show black with brief faint period of an image. Did i damage my goggles by removing the receivers and keeping it power? Did i over heat my goggles?
I found a problem where I soldered the video wires from the camera and the VTX and I got video but now I don’t have my OSD. What do you think I should do
You need to run the video wire through the FC to get OSD. The FC cannot insert OSD into the video if you bypass the FC by wiring the camera direct to the vTX.
Sometimes the white or bright spaces in the Video are flickering. What could be the reason? I got it powered with 5v of the video transmitter. Sometimes it works fine. :/
I lifted my ground wire to the VTX today. I quick fixed it by taping the ground wire to the USB connector socket. Flew my other 15 batteries no problem.
Hello and thank you for the video. I have a Promark Shadow gps quad and the camera is not that good. Can I replace the existing camera with a micro hd ? If so , will it be a plug and play or do I have to rewire it and supply a battery to power it. Will I keep my osd ? I have yet to check the output voltage to my Promark's camera, I can't find any specs or info on it. it will have to be small enough to replace the original camera and keep it in the housing. This would allow me to keep the tilt function of the camera. Is there is a better quality camera that would also work ? Thank you.
Hey, josh I had a question about dys f4 pro I have three lights on it led's. One green which is not working I only get blue and red lights now my osd has nothing just black, but I dont get any beta flight start up menu at all just wonder what that means, I did have it plugged in with out antenna just wonder if that would make me lose video? thanks
My Omnibus F4 doesn't pass the camera signal, but it shows the OSD just fine. I just see black screen with OSD. I tested the camera separately and it works just fine. What could it be? And yes, lens cap is off.
If you see black screen with OSD then yeah the FC and vTX are wired correctly but the camera is not sending signal to the FC. If you tested the camera by itself then you know the camera is working. So it must be the video input on the FC that is not right. First thing I would check is, did you solder to the right pin?
@@JoshuaBardwell Yes, I soldered to the right pin(and I'm sure the schematic is right because I have 2 boards and one is working fine). I noticed that sometimes( not every time) the camera makes an high-pitched humming noise(like the one in the video)and doesn't output a signal. It does that only when plugged in the 5v in, in VBAT it works fine... Thank you very much for your help and the amazing videos you make!
I'm having an interesting issue. I have two quads both with VKK vtx . One has run cam owl 2 the other has foxeer arrow micro v2. On one quad I can plug in either camera and it's fine. On the other quad I plug in runcam and it's good, but if I plug in foxeer, the camera has a high pitched noise and I only get black screen. I know vtx is good becuase I can see OSD. foxeer cam doens't make a high pitched noise on the other quad where it works fine. I'm scratching my head and have a run cam eagle micro on the way just because. Any suggestions?
My basically new foxeer falkor had the black screen of death after the most minor crash. It was a careless mistake... I just took off and the prop hit a wooden seat for half a second before i disarmed and it only fell a foot to the ground onto grass, the prop was not even bent. In my case I have no OSD, straight black screen with no static. The VTX works because I get normal signal. All the connections seem fine and I plugged another foxeer micro camera in and it works fine. Im just stumped because it was such a minor impact and all the capacitors etc on the camera chip seem unconnected and brand new... Im guessing the prop hitting the wood vibrated the quad so hard it shook something internal on the camera chip and killed it. In my case I had a full size camera on a frame that would only just fit the camera between the two carbon mounts. From now on I wont be mounting cameras directly to carbon fibre via the camera screws... Some soft washers or something to dampen vibration/impact are going between there for sure.
I had a Tramp VTx that was making that high pitched humming sound and it would go away when I wiggled the ground wire, suggesting a dodgy connection to ground. Unlikely it's the VTx in this situation as it was transmitting fine, just no image from the camera. But... maybe it's a flakey ground wire between VTX and camera? Can't say I understand why a flakey wire would induce an inductor hum, but thought I'd share my only experience with that high pitched hum in case it helps.
How is the camera powered, 5V or Vbat through the Betaflight F3 board? If it was a bad 5V voltage regulator on the board (that didn't give 5V out at all), then the OSD/Betaflight board would also be affected. However if that voltage regulator was giving out less than 5V when it was making that noise, that could be a problem for the Runcam? See if you can measure the voltage going to the camera. It could be a bad connector going to the camera or cabling, try to wiggle the cable / connector around a little bit. Also you showed plugging the camera in while the quadcopter was already powered up, what if you repeat the initial problem - plug the camera in and plug in the Lipo, and repeat unplugging/plugging the Lipo a few times.
I crashed and now have a black screen with osd on the screen. No humming noise and all wires appear to be connected. The camera didn't suffer any damage in the crash...it hit the ground on the battery. So do you have any idea as to why the camera isn't working? Its the twig 115 hd .
The camera isn't working because you crashed 😜 Check the wiring then if that is all OK replace the camera and see if that fixes it. If so, throw out the old camera.
If the camera works on the bench with 4s, its got to be worth rewiring the cam with a new cable, maybe with power direct from battery, Shame to toss a $50 cam for the sake of a $2 lead! Admittedly its hard to know where the hum was from unless it was the cams internal voltage regulator failing.... but you never know with intermittent connections.
I've had this same problem with my betaflight f3 board joshua, but the camera still worked, just the whine. the weird thing was it only made the whine when powered from the USB. I swapped cameras, the whine went away and all is good. just an FYI the mount holes on the BFF3 board are grounded. I think some BFF3 have issues with some cams, but that shouldn't be it.. who knows. I've put a ton of packs through and the flight controller is still fine. Weird stuff isn't it?
You’re probably not gonna read this but I have a small FP camera all in one channel only and I have no idea why commands please can you respond to this if you have any idea how I can change the channels on a small at the camera but when it when I’m not changing the channels I’m the only one at the camera just please sorry if the spelling is crazy because I am using the voice thing on my phone
Today i ran my quad with 1300mah 4s dinogy gr2.0. (They are crap). First pack.. I flew the quad normally hard and after 1.5 minutes the video feed went all black.. first time it has happened. I went fast so i just decided to crash the quad. No harm to it and it flew more than great the next 15 packs out problems. I power the vtx from 12v on pdb The cam gets from vtx. And when i cant find any reason for the blackout in videofeed i just feel i cant trust the quad anymore. Any Idea?
Black screen usually means the camera powered down or lost connection. The most common cause is a loose connector, broken wire, or bad solder joint. If the camera is being powered off of 5v, it could be a bad voltage regulator.
I have the same.. on my third battery half way my screen turned black. Last time I had no signal anymore, then it worked again. Now I have signal but screen black.
Maybe the plug on the runcam I had the wire break right behind the pin the insulation was holding it together and it did this from time to time didn't realize that's what it was until the insulation broke. New connector never had the problem again
I have a sparrow and it reboot in loop for first 45 sec and it stabilizes. Generally that just happen on the first lipo pack of the day. last time I got a black screen with osd in mid flight. I can't trust it anymore. I also have a runcam 2 and it turn off randomly.
I bet this wouldn't have happened if you used the thru holes. 999 times out of 1000 not using thru holes correctly will work just fine, but why not avoid things like this all together, while making your build easier and cleaner? I totally understand it's a pain to rework them, but really though, who reworks there stuff these days? I am not trying to bash you, and never was when i mentioned this before. Murphy's law is real. BTW great work with everything you do, and thanks a lot.
Joshua. Me and a friend have had similar issues but different. When wired the way your supposed to the 5v to the camera seems to go low under punch outs. And cams brown out. We both have had to run raw power to the cameras and battery voltage from BFF3 to the vtx. Seems the 5v regulator to be the issue. Also the crosshair in osd won't display, maybe it's because accelerometer is off. Maybe this will help you out, you have endlessly helped me!
Hi, it happened so many times with me to have the connection to the camera loosening out. Crashes or vibrations can make the socket move just enough to break one of the contacts to the cam. I'm betting your setup is fine, but it will happen again. I hot glue all my camera sockets now. Ah and I thought the noise comes from voltage regulators.
So I have the eachine wizard x220s and the fat shark scout v4, I can’t connect the two (I have done it a few times before but I can’t now) I’m on the right band and channel (I’ve gone through all bands and channels), I checked circuitry connections and it’s all fine what’s going on???
i building a drone for a friend and he has the same exact googles i do but for some reason i cant find video on his goggles but i can find it no problem with mine what would be causing this issue i cant figure it out. the goggles are teleporter v5
Caddx Turtle V2 - Same problem. Lost the camera due to a broken power feed to the video card w/ the DVR. Once fixed the video came back briefly but was gone again on the next flight. WTF? Finally tried pushing this button on the side of the DVR card and viola! The video is back BUT when I power cycled the video disappeared again until I did another long press on the video card button. Again WTF? Went into the configuration menu for the DVR card (plug in the omni control that came in the box) and decided to do a factory reset of the video card. BINGO! The video now powers up with the Beta Whoop.
OSD still working confirms the FC and vTX are good. Check the video wire going from the Split to the FC. Check the ribbon cable between the camera and the Split.
Thank you fixed out the blackout problem now I have a new one hope you can help now when I power up the Drone the video signals fine but as soon as I switch to the model on my taranis qx7 the video starts cutting out what do you think could be the problem thank you for all the great advice love your videos
So if I’m not getting any video or OSD that means my FC is the problem? I’m just getting a black screen with no OSD. I have another copter that uses the same board. It has the same issue as well. They are both flycolor raptor s tower stacks
Joshua Bardwell that’s exactly how I determined the problem lies with the FC. It uses a pass through function with the FC. Vtx plugs into it and then the camera plugs into it as well. I could always go the old fashioned way and connect them to the pdb and it should work fine. Thanks for the reply back!
"What a hassle" 4:29, those words make me feel very content that I'm not alone in the struggle against tedious drone fixes.
you know what's hilarious is I had the same problem so I took my camera out put it back in and the problem was solved. so I guess you helped me fix it but neither of us know how lol.
2 years later an still a mystery
just had the same issue! unplugged it a few times already. then while i was watching your video i was playing around with my multimeter and plugged it again. Then for some reason bingo i’ve got video ?
Mine was the a bad solder, ground decided to unsolder itself between the RunCam split and the FC. Pretty much had to remove the VTX and the RX to then even get a glimpse of the area. Was a complete pain in the butt although I really feel good knowing this noob can troubleshoot. Getting more and more confident every day. Appreciate the work you do JB!
I actually had this issue with a customer using that same setup. Replaced his board and same thing on new one. Turned out to be the camera exactly like what you found. Great video!
Cap on lens. #solved
Kidding... kidding... Kind of.
fellstar have had this before
I Had to double check my copter lmao
I was just investigating a similar problem. I got the OSD on the screen but image was grey. After some investigation I noticed, that the flight controller was outputting 0.5V on the 5V rail. So I tested the other 5V rails and there were multiple ones too low. However I found a functioning 5V output and tried that for the camera and it immediately worked. In your case it was likely to be the flight controller as well, because a) the camera gets it's power from there (I'm assuming) and b) this noise comes from the coils when there is something wrong with the switching frequency. This noise often occurs when the switching power supply is idling (and thus turning down the pwm signal into the audible frequency) - this is also why you mostly hear smartphone chargers humming when they are left hanging on the wall without charging a phone..
"Damn, my $65 camera is working, what a shame..." :D
I asked you on a live streama few months back if OSD chips are interchangeable, you said yes and I've since confirmed it to be true......ordered a few blank chips and yes they work. I had a Diatone Mamba V1 on my Chameleon that lost OSD. I put in a Foxeer Razer for the OSD as opposed to swap the FC. Then the chips arrived and I changed it out on the FC......still no joy. The Razer camera accidentally shorted and went black which forced me to troubleshoot all. Found a microscop[ic solder ball on the FC. Isopropyl bath and all is well. Video, OSD, and A new Ratel.
I had an issue with a black camera on my Eachine wizard after i re-mounted it in the quad after a hard crash. The screws I was using to mount it were just the exactly correct size to just barely touch the board inside of the camera case just slightly. What I was seeing in this case was that I would arm the quad and the camera was visible but as soon as I moved the throttle up slightly the video would go black. I discovered this by removing the screws from the camera altogether and testing again. Check the tightness of your side-mounting screws on the camera inside to make sure they are not touching the board perhaps? I even added a small strip of electrical tape inside of where those screws were to make sure they didn't touch again as well as adding a nylon washer.
I am having your problem but i can't understand how to solve
my vtx fried and i replaced it then i had some vidue issues (osd but no video) slightly losening the screws on the cam solved this! thnx!
Thank you, I have same issue today and this solved my issue.
I had my wizard x220hv completely rebuilt with just the frame and motors are from the original. I'm using a newer foxeer camera and it was all fine in the past two years withstand many crashes until today I discovered one of the side mount screw was lost and the video got a bit shaky and jelly-like, so I decided to tighten the other side screw then I was getting exactly the same issue you described, the quad lifted in the mid air and screen all black. Tried best to land it and damaged a GPS module 🤷♂️.
I have had kind of the same problem. I had a screw barely touching the motors windings where they come out of the motor. When my top plate was mounted with the SMA connector touching the carbon, it was backfeeding the voltage from the motors into the antenna ground and wreaking all kinds of havok. Since you get a straight up black screen of death on the camera, I would check for any point that may be shorting out to the frame, and backfeeding into the antenna SMA.
I know the issue! Just spent 3 hours this past weekend rebuilding the quad from the ground up to finally figure the stupid problem... Your screws are grounding with the camera! I bet if you put it back together,you will get black vid again! But if you un-screw the camera, video will come back (NTSC NOT DETECTED)! WALA! Problem SOLVED!
I had the same issues with a couple Runcam Swifts. The mounting screws (the ones included with the cam) went a little too deep inside and were just barely coming into contact with the SMD caps on the edge of the board. This caused me a ton of frustration due to seemingly random camera blackouts until I discovered the source of the problem.
I literally put the quad apart twice and redid al the soldering! When I was about to give up! I figured this out! It was super frustrating!
Thanks for the heads up. I haven't had that issue but If I did I would never expect to look at that. Good knowledge for the future.
Tim Spitz after a crash my eagle has black screen but opened cam up and made sure all boards haven't separated but lens looks like it's slightly bent (as if cross threaded )so could it be the lens being not square to the first board?? Not had the cam long
For those of you reading this in the future. I also had the same exact problem. This guy is correct it is the screws. You will know it is because if you disconnect your camera and reconnect it lose it will show you video again. Then mount it and you get the blackness but still see the osd. Take out your screws filed them down with 600 sand paper, or a file. reassemble and your good to go. Thank you dex FPV.
could always do for the old standby of a couple of chilling cycles (spray can cooler) targeted at the FC and PDB then retesting.
if the surface mount soldering iron a component is tired and emotional this usually gets it to make itself known.
Perfect timing for this video. I ejected my Runcam Eagle while flying today and now have a black screen with working OSD. Since the crash was hard enough for the screws to take chunks out of the camera case and rip the wires out of the connector, I'm going to guess (hope) that it just broke a solder joint on the PDB and didn't kill my new camera.
Have U the "-" pole connected to the carbon frame? There can be "transition resistance" between frame and pdb/fc when the screws are tight
So Funny!!! I just finished fixing this same problem. Black Screen situation. And then I sit down to watch videos and this was the first one up. After trouble shooting everything, I discovered a short in the middle of a ground wire between the osd connection on the flight controller and the video transmitter. I saw a kink in the wire, and discovered no continuity in the wire, it was broke. Changed the wire and good to go.
Nice video...had the exact same problem black screen (minus the humming) just abt two weeks ago. It turns out the pdb pads powering the camera was faulty...i moved the wires and powered them from the pads that the vtx was powered from and it worked fine...until i crashed and broke my quad :)
What about an issue where the video signal and OSD is fine sitting idle on the bench, but as soon as you throttle up, the video signal cuts to grey but OSD is still fine.
That points to the camera wires. They're daged and the vibration is making them come loose.
@@JoshuaBardwell oh interesting! It's a brand new Mobula 6 too. 🙄 Guess It's time to resolder the camera...🤷♂️ Haha thanks for the response man, I appreciate it! Keep up the great work!
I HAVE HAD TO RE-BUY ALMOST EVERY PART OF MY QUAD DUE TO CRASHES AAAAAAAHHHH!!!!!!!!!!!!!!!
Guess this is my life now.
I had this exact problem and 2 days I studied the quad but it was just the signal connection plug on the camera led backed out a bit.
Interesting, I had the exact same symptom yesterday with my brand new Betaflight F3 FC. I unplugged the camera and reseated the plug and it was fine. Could there be a bad batch of FC's out there?
I had the same problem yesterday while setting up two mini quads. I am using Runcams 2, a FT951 25mW VTX and a AOMWAY 200mW VTX. While the first VTX doesn't send any voltage to a camera, the AOMWAY was sending 4.99V to the camera and nothing happened. The only way to solve this issue was to power the camera from the PDB, directly from the battery. I might have done some mistakes, I don't really know, but I spent 2 days trying to figure out what was wrong and the only working solution was this one...
Have used the auto scan.
I did leave them in the van for a couple of days over winter in below zero conditions, it's been suggested that some moisture may if got inside and has knackered them. Had my new goggles delivered yesterday so I'm trying some trouble shooting myself. Iv also wired up a new eagle2pro so going over these conections to👍
I just heard a similar buzz/hum on a new build. It only sounded off for a few minutes before the PDB smoked. It really blows to have to disassemble a new build and start over with all the connections.
In my Setup the camera(caddx ratel) almost always works really well without a black screen. But sometimes theres no video but theres always osd. When I get a black screen and then unplug and plug the battery the video comes back. Why would that be?
We tend to discount the idea of the camera going bad, but they can be damaged from a hard impact dispite appearing physically undamaged. I recently had to replace TWO foxeer HS1177 cameras that looked totally fine, yet were doing a wierd black screen with glitchy green stripes. Just bad luck, I guess!
possible bad solder joint? jiggling the wire made a connection?
that's my thought...
Michael Brewer Yep, that's it most likely. My PDB makes that same high-pitch noise when the camera +12V is not connected but signal is.
Joshua Bardwell Did you find solutioN? I got the same problem! on my betaf3 fc
+eloy gambin not yet. I don't think it's the camera though.
I have changed the camera for a brand new, let's see what happens!! BTW Joshua, Did you have problems soldering the GND pads on the Betaflighf3 FC??? All my GND (holes) and somes of the ESC signal couldn't be soldered properly
I love this video Josh!! I love your reaction when it ends up fixing itself. We explain the technology involved in this kind of repair as FM... or F#%king magic.
I went through this for a couple weeks when I bought my premium, spared no expense, TBS Unify HV. Now it is finally behaving ( even though it's hooked up exactly the same way it always was when it wouldn't work right), and I just have to fly everyday... waiting for it to screw up again.
Thanks Crappy!!
Pfm is real
Hey Joshua! Im having this problem if my emax tinyhawk rtf kit. The other day my gogglea have a black screen and I have a signal shows the ch/Dr in the corner. Was about to take it apart and re so the wiring! Seeing id you could help me out
Seth Carmony me too yet I didn’t buy the rtf kit :/ I got the goggles and TinyHawk s and a frsky radio. I get a black screen and am unsure what to do because I don’t want to take it apart
When you plugged battery back in there was no camera so no/less load on inductor, then plugged camera in...
Have you since plugged battery in with camera already plugged in yet?
Im thinking it could be starting up with extra load on poor/dodgey/on-it's-limit inductor...
I only ask as you didn't test again in video under 'exact' same circumstances as when fault was first happening & we all know how fickle eleaktrickery faults can be ;)
Orr, could a weak connection somewhere induce such a noise from an inductor similar to (for example) a lose fluro tube does from its capacitor when they won't start up properly until connections are 'wriggles'?
Sorry, you've likely covered this by now, just thinking out loud...
Give it an extra hard rag'n & see what it does! :D
Same issue today re-soldered camera connection and now it’s fine this is a connection issue with the camera
Mine was working fine till a hard landing, disconnected cam so i plug in and nada. BLACK SCREEN, OSD working copter is flyin but no video . I plugged ina nother cam & nothing so not sure yet
new intro looks sweet!
I had the same issue with my runcam and it turned out to be that the plug was not making 100% contact. However is was seated flush. I plugged it out and back in without any issues
hey i got the runcam micro swift 3 and i’m getting the same is where it’s a black screen. The only thing my black screen says is batt
I have been having this issue lately with one camera in particular. The camera was initially on one of my quads(call it X) which has a rrosd and i kept getting a black display in my goggles whereas if i connected the cam directly to a display monitor the cam would work perfectly fine. Then during a race this sunday i had to swap cameras between quad X with the cam issue to a race quad(call it Y). The cam displayed the same black screen issue on quad Y as well which has a HUBOSD on it. When i put another identical cam (i use the HS1177) on quad X i didnt notice this black screen issue anymore, hence i ruled out that the rrosd might be bad. Now coming to quad Y, i can get the image to appear by connecting and disconnecting the quad power supply 4-5 times and eventually the image pops up. Now i was skeptical to fly quad Y with such an issue but didnt notice any issue inflight (despite hitting gates etc and still the image didnt disappear ruling out a loose wiring i guess). So i think it is actually a cam issue cause it does work eventually when i plug the power in and out a couple of times till i see the image instead of a black screen. Not sure whats exactly wrong, maybe this particular camera board is more susceptible to power surge during lipo plug in on a quad due to some damaged internal component? Hope i was clear in what i was trying to say ;)
Devesh Sharma I have the same issue. Mine normally works but sometimes on power up it's a black screen. It usually fixes itself with just one or two power reboots.
Hello, i crashed my quad and the antena came off the vtx. I decided to solder and when removing the vtx I ripped off the plastic connector for (video, ground,Rx,5v).i did a horrible solder job and when power on drone little smoke came out and led lights are not working anymore . I ordered a new vtx .ordered the same one I had and just plugged everything in but vtx not turning on or the FC not recognizing it . Everything else seems to work .motors and everything. But not the lights not vtx. Could the FC be fry just in one part or when it does it does completely and nothing works . Please any answers will help .I'm struggling .
you glazed over the Furious FPV Fatshark Battery, I want!
i get a black screen when i solder on smart audio but the osd from it is there, but than when i solder it differently i get the camera video but no smart audio.
Crashed my quad today in the sand at the park. Everything seems to be working fine except all I get is static on the video. I'm really new to this but I assume the VTX is bad which sucks because tall the solder connections are super tiny in this cinewoop.
BFF3 appears to have a weird issue for some. Same issue here:
-VIDEO + OSD overlay worked for a few seconds. Afterwards, only OSD would work (black video)
-Plugged in/out lipo a few times. No changes.
-Wanted to record a video for FPVMODEL's support. Video + OSD works.
Tried two different cameras and brand new unify race video transmitters.
Did not change a single thing in the meantime (wiring).
Same issue as described by CONRADM over at rcgroups.
I just recently had an experience where I got a black screen, so I figured it was an issue with the camera. So I swapped the camera, and still got a black screen. So I connected the original camera directly to VTX and then the VTX wouldn't turn on unless I disconnected the camera. So I swapped the VTX and wired everything back to the flight controller and still nothing lol so again I connected the new camera to the new VTX and then it finally worked. Turns out the VTX, camera, the CamS pad and the VTX S pads on the FC all stopped working at the same time after a crash. So I had to buy an entire new video system along with a flight controller.
wow i think this is whats happening to me i didn't crash jusst hard land kock loose the camera after plugging back in igot black screen. Tried another camera and still nothing
Thank you for the video. The method worked for my Foxeer Monster V2 as well.
Wow I just had a similar issue last night. Ended up being the tx wire off the FC to my osd came loose after a crash.
okay so i have a working powersuply i just cant get video from my fatshark teleporter v4s i have osd and there is no humminh
Obviously too late for me to comment on this but I had the very same thing and it turned out that the camera did not like having power off of the FC, when I hooked it up to an external transmitter while keeping it's single through the FC it worked fine! I hope this would be of any help!
my assumption is that it's your power supply you have a transistor that's about ready to go mosfet regulator I used to have the same problems with some of my ham radios I used to run when there's a spike usually he'll start to go bad try putting it under more of a load and see if you can get it to do it then like hook up a second camera good luck keep up the good videos
Hi What would case my camera to be black and white on one set of goggles but OK on another
This happened to me when I replaced my VTX. Checked for shorts, tested camera and everything seemed fine. I go back to the wiring diagram for the VTX and realised I missed a bridge connection
My vtx only transmits at a certain angle... Any tips?
Best guess would be a bad solder point? By tipping it a certain way maybe it makes the connection??? Definitely a weird one...
My FPV camera shut off when I'm throttling only when the camera is recording in FHD at 60fps, it's not happening at 30fps or when not recording. black video with OSD. the camera is RunCam Split3 Lite, drone still flies while this happen. the FC is brand new (F4 ELRS AIO board), but then i checked that 1 motor is broken, still diagnosing..
Hey Josh I have a question I'm really kind of stuck. I put on for new motors on my quad copter which flowed perfectly fine before hand. When I put him on the motors were going in the wrong directions which made the copper go haywire on the bench. So then I reversed caveman style the wires and got the motors going in the right direction and it flew fine. But now my goggles my fat shark diversity only getting a gray screen I'm getting OSD but I'm not getting any video help
I have an issue with my camera and can't seem to find another example of it. There is what looks like horizontal white noise but goes away when I put my hand near the lense and when I take my hand away the white noise returns, can't figure this out🤔
Since it goes away when you touch the lens, it's probably grounding. A couple things to try are, 1) isolate the vTX SMA connector from the frame, and 2) make sure camera and vTX are grounded to the same place.
Still haven't figured out the problem. I really wish it wasn't just a fluke in your case. I just can't figure out what's going on. Cam works on other quad just fine, please help!
What about a black square almost completely covering the video feed? I saw the video on the edges then came back.
I have it on DVR. I'm surprised I didn't crash it.
My problem is blank screen when powering the camera from the quad, but if I power directly from the battery everything works fine. Ive tested the quads power supply and the power lead im using is giving a healthy 12.14v so I dont get whats wrong.
This happened to me just today on a Mobulite6: camera (runcam atom) goes black while flying, osd stays. Camera comes back after a reboot. I'll try to change the camera and see if that fixes it, but given the symptoms I guess it won't
Hey I just experience that same issue did u find a fix or what the issue might be ?
Had a black screen myself, intermittent at first but after a crash completely black.
Turned out to the the (yellow) video cable from the HS1177
I'd try plugging in the battery a few times to see if I could replicate the issue and then trace the sound.
It could be one of those things where something has a problem initialising sometimes but once it's on it's on.
What do you do if you don’t have access to a screen
None of my cameras have ever came with a test cable, anyway I could make one?
I'm pretty sure its just a matter of plugging in the necassary cables;
Red to + 5v
black to ground, you should be able to use a usb cable,
yellow to a RCA-video jack main plug and negative from usb on the shield
I just recieved a runcam and did a build with it. Everything runs fine as well as the osd. Ive got no humming noise. The solder joints are very nice. No bridging between joints.. Its an brand new runcam. I could try a different camera to see if it works, i suppose. Ita a Runcam Swift 2 and it never came with the old school aux. connectors. Blehhh ha
Can you recommend a budget field monitor like yours? Looks like it has a receiver built in or you can connect with a cable. Thanks
My camera blacked out a few times a one quad today. Of course it never did it on the bench, only after being in the air for 30-60 seconds. I guess I'll take it apart, check solder joints, wiggle some stuff, and put it back together. And see what happens.
I saw the comment on grounding with the screws below but my camera is mounted on small TPU parts that came with an RDQ Mach One. So I don't think that's it.
Hello Mr.Bardwell,I was curious if you ever received your hglrc f3 v4 aio fc? I have mine in a x210 frame with a lumineer pod, it fits well but after setting the board up in bf, witch everything went without a hitch nut the maiden went way wrong!! Copter flipped over and out lol!! I kno you are super busy, just thought I would see where you were at with that board? I'm starting to think there's some serious issues with this board, especially now that the v5 just come out???!!! Anyhow, have a good one, and love what ya do!!! Jessie.K
+J.FINESSE FLIGHTS I have heard so many bad reports of this board that I have hesitated to install it.
Dammit! I have the same problem with my Chameleon, I guess I'll have to bring it to Kwad camp so you can troubleshoot it.
hey Joshua Bardwell, love your channel I've learned alot thanks to u!
I was wondering if you could explain the mechanism/chemistry within a lipo that effects c rating. Is it really all it's cracked up to be or is it just a lot of magic smoke and mirrors?
Thanks again, keep up the good work
+Liv and Lexi Lance Wallen Interview: czcams.com/play/PLwoDb7WF6c8lXHxlVhnIXPpE44mYOQYFr.html
Mounting screw shorting inside the camera causing a lot of current draw on the regulator that is powering it. When the camera was pulled out that moved it just enough to get rid to the short? At least that is what happened to me with my 1177 but in was more permanent.
But then i read further and find you are powering camera and vtx of vbat so never mind.
Hey dude I jus squires new copter. Straight newb. But uh ya the runcam2 has a floppy yellow wire is it pretty hard to solder it up also has brown epoxy do u know how to remove without ripping stuff apart to have clean solder area? Do u hav a vid doing this or?? Can u help guide a newb
I see that your camera actually works, but every time i've had black video, it has been because of a damaged camera circuit board. If i press on the board the video will work. This usually happens after a really hard hit to the camera and nothing seems to fix it.
Same for me here. Those RunCams suck...
Anyone, I use flight sight goggles and i forgot to one day unplug the battery and removed the receiver antennas. When i went out to fly again the next week, i noticed my goggles no longer show static, just black, i can move through the menu and everything. But when i broswer the frequencies i can only find one channel that show black with brief faint period of an image. Did i damage my goggles by removing the receivers and keeping it power? Did i over heat my goggles?
I found a problem where I soldered the video wires from the camera and the VTX and I got video but now I don’t have my OSD. What do you think I should do
You need to run the video wire through the FC to get OSD. The FC cannot insert OSD into the video if you bypass the FC by wiring the camera direct to the vTX.
Sometimes the white or bright spaces in the Video are flickering.
What could be the reason?
I got it powered with 5v of the video transmitter.
Sometimes it works fine. :/
an oldie but goodie
I lifted my ground wire to the VTX today. I quick fixed it by taping the ground wire to the USB connector socket. Flew my other 15 batteries no problem.
You're a gutsy pilot to fly with such a tenuous connection to your camera. Glad it worked out.
Hello and thank you for the video. I have a Promark Shadow gps quad and the camera is not that good. Can I replace the existing camera with a micro hd ? If so , will it be a plug and play or do I have to rewire it and supply a battery to power it. Will I keep my osd ? I have yet to check the output voltage to my Promark's camera, I can't find any specs or info on it. it will have to be small enough to replace the original camera and keep it in the housing. This would allow me to keep the tilt function of the camera. Is there is a better quality camera that would also work ? Thank you.
had same issue, just been short or something no idea... , I connect straight from battery and everything works fine.
Hey, josh I had a question about dys f4 pro I have three lights on it led's. One green which is not working I only get blue and red lights now my osd has nothing just black, but I dont get any beta flight start up menu at all just wonder what that means, I did have it plugged in with out antenna just wonder if that would make me lose video?
thanks
My Omnibus F4 doesn't pass the camera signal, but it shows the OSD just fine.
I just see black screen with OSD.
I tested the camera separately and it works just fine. What could it be?
And yes, lens cap is off.
If you see black screen with OSD then yeah the FC and vTX are wired correctly but the camera is not sending signal to the FC. If you tested the camera by itself then you know the camera is working. So it must be the video input on the FC that is not right. First thing I would check is, did you solder to the right pin?
@@JoshuaBardwell Yes, I soldered to the right pin(and I'm sure the schematic is right because I have 2 boards and one is working fine).
I noticed that sometimes( not every time) the camera makes an high-pitched humming noise(like the one in the video)and doesn't output a signal. It does that only when plugged in the 5v in, in VBAT it works fine...
Thank you very much for your help and the amazing videos you make!
I'm having an interesting issue. I have two quads both with VKK vtx . One has run cam owl 2 the other has foxeer arrow micro v2. On one quad I can plug in either camera and it's fine. On the other quad I plug in runcam and it's good, but if I plug in foxeer, the camera has a high pitched noise and I only get black screen. I know vtx is good becuase I can see OSD. foxeer cam doens't make a high pitched noise on the other quad where it works fine. I'm scratching my head and have a run cam eagle micro on the way just because. Any suggestions?
My basically new foxeer falkor had the black screen of death after the most minor crash. It was a careless mistake... I just took off and the prop hit a wooden seat for half a second before i disarmed and it only fell a foot to the ground onto grass, the prop was not even bent. In my case I have no OSD, straight black screen with no static. The VTX works because I get normal signal. All the connections seem fine and I plugged another foxeer micro camera in and it works fine. Im just stumped because it was such a minor impact and all the capacitors etc on the camera chip seem unconnected and brand new... Im guessing the prop hitting the wood vibrated the quad so hard it shook something internal on the camera chip and killed it. In my case I had a full size camera on a frame that would only just fit the camera between the two carbon mounts.
From now on I wont be mounting cameras directly to carbon fibre via the camera screws...
Some soft washers or something to dampen vibration/impact are going between there for sure.
I had a Tramp VTx that was making that high pitched humming sound and it would go away when I wiggled the ground wire, suggesting a dodgy connection to ground. Unlikely it's the VTx in this situation as it was transmitting fine, just no image from the camera. But... maybe it's a flakey ground wire between VTX and camera? Can't say I understand why a flakey wire would induce an inductor hum, but thought I'd share my only experience with that high pitched hum in case it helps.
How is the camera powered, 5V or Vbat through the Betaflight F3 board?
If it was a bad 5V voltage regulator on the board (that didn't give 5V out at all), then the OSD/Betaflight board would also be affected. However if that voltage regulator was giving out less than 5V when it was making that noise, that could be a problem for the Runcam?
See if you can measure the voltage going to the camera.
It could be a bad connector going to the camera or cabling, try to wiggle the cable / connector around a little bit. Also you showed plugging the camera in while the quadcopter was already powered up, what if you repeat the initial problem - plug the camera in and plug in the Lipo, and repeat unplugging/plugging the Lipo a few times.
vBat through the BFF3 pad.
I crashed and now have a black screen with osd on the screen. No humming noise and all wires appear to be connected. The camera didn't suffer any damage in the crash...it hit the ground on the battery. So do you have any idea as to why the camera isn't working? Its the twig 115 hd .
The camera isn't working because you crashed 😜
Check the wiring then if that is all OK replace the camera and see if that fixes it. If so, throw out the old camera.
Hey did u ever find a fix ?
If the camera works on the bench with 4s, its got to be worth rewiring the cam with a new cable, maybe with power direct from battery, Shame to toss a $50 cam for the sake of a $2 lead! Admittedly its hard to know where the hum was from unless it was the cams internal voltage regulator failing.... but you never know with intermittent connections.
I've had this same problem with my betaflight f3 board joshua, but the camera still worked, just the whine. the weird thing was it only made the whine when powered from the USB. I swapped cameras, the whine went away and all is good. just an FYI the mount holes on the BFF3 board are grounded. I think some BFF3 have issues with some cams, but that shouldn't be it.. who knows. I've put a ton of packs through and the flight controller is still fine. Weird stuff isn't it?
You’re probably not gonna read this but I have a small FP camera all in one channel only and I have no idea why commands please can you respond to this if you have any idea how I can change the channels on a small at the camera but when it when I’m not changing the channels I’m the only one at the camera just please sorry if the spelling is crazy because I am using the voice thing on my phone
Where did you get that cable to connect the camera to the screen?
Today i ran my quad with 1300mah 4s dinogy gr2.0. (They are crap).
First pack.. I flew the quad normally hard and after 1.5 minutes the video feed went all black.. first time it has happened.
I went fast so i just decided to crash the quad.
No harm to it and it flew more than great the next 15 packs out problems.
I power the vtx from 12v on pdb
The cam gets from vtx.
And when i cant find any reason for the blackout in videofeed i just feel i cant trust the quad anymore.
Any Idea?
Black screen usually means the camera powered down or lost connection. The most common cause is a loose connector, broken wire, or bad solder joint. If the camera is being powered off of 5v, it could be a bad voltage regulator.
I have the same.. on my third battery half way my screen turned black. Last time I had no signal anymore, then it worked again. Now I have signal but screen black.
Maybe the plug on the runcam I had the wire break right behind the pin the insulation was holding it together and it did this from time to time didn't realize that's what it was until the insulation broke. New connector never had the problem again
This is a good suggestion, and would be consistent with the camera working from the pigtail but not in the copter.
I have a sparrow and it reboot in loop for first 45 sec and it stabilizes. Generally that just happen on the first lipo pack of the day. last time I got a black screen with osd in mid flight. I can't trust it anymore. I also have a runcam 2 and it turn off randomly.
I bet this wouldn't have happened if you used the thru holes. 999 times out of 1000 not using thru holes correctly will work just fine, but why not avoid things like this all together, while making your build easier and cleaner? I totally understand it's a pain to rework them, but really though, who reworks there stuff these days? I am not trying to bash you, and never was when i mentioned this before. Murphy's law is real. BTW great work with everything you do, and thanks a lot.
Joke's on you. I used the through holes on this build.
Drats! foiled again
The BFF# is hard enough to solder to that I wasn't getting clean connections using my usual method. So I went through hole.
Joshua. Me and a friend have had similar issues but different. When wired the way your supposed to the 5v to the camera seems to go low under punch outs. And cams brown out. We both have had to run raw power to the cameras and battery voltage from BFF3 to the vtx. Seems the 5v regulator to be the issue. Also the crosshair in osd won't display, maybe it's because accelerometer is off. Maybe this will help you out, you have endlessly helped me!
+Jesse s&w it's definitely not the regulator because the camera and vTX are running off of vBat.
Hi, it happened so many times with me to have the connection to the camera loosening out. Crashes or vibrations can make the socket move just enough to break one of the contacts to the cam.
I'm betting your setup is fine, but it will happen again. I hot glue all my camera sockets now.
Ah and I thought the noise comes from voltage regulators.
So I have the eachine wizard x220s and the fat shark scout v4, I can’t connect the two (I have done it a few times before but I can’t now) I’m on the right band and channel (I’ve gone through all bands and channels), I checked circuitry connections and it’s all fine what’s going on???
Possibly the vTX is not powering on? Does it get hot? If it's cool then it's not powered up.
Joshua Bardwell it does get rather warm
Joshua Bardwell I cant think what I could do, I don’t have a wire to connect it to my tv or pc monitor
i building a drone for a friend and he has the same exact googles i do but for some reason i cant find video on his goggles but i can find it no problem with mine what would be causing this issue i cant figure it out. the goggles are teleporter v5
It doesn't seem likely that the goggles are damaged so I am going to guess you are just not tuning to the right channel.
Caddx Turtle V2 - Same problem. Lost the camera due to a broken power feed to the video card w/ the DVR. Once fixed the video came back briefly but was gone again on the next flight. WTF? Finally tried pushing this button on the side of the DVR card and viola! The video is back BUT when I power cycled the video disappeared again until I did another long press on the video card button. Again WTF? Went into the configuration menu for the DVR card (plug in the omni control that came in the box) and decided to do a factory reset of the video card. BINGO! The video now powers up with the Beta Whoop.
Just purchased a runcam split V2 was flying today and the screen blacked out on me any tips on a fix or is it a bad camera. OSD was still working
OSD still working confirms the FC and vTX are good. Check the video wire going from the Split to the FC. Check the ribbon cable between the camera and the Split.
Thank you fixed out the blackout problem now I have a new one hope you can help now when I power up the Drone the video signals fine but as soon as I switch to the model on my taranis qx7 the video starts cutting out what do you think could be the problem thank you for all the great advice love your videos
Hi i tried this and it did not work any ideas?
So if I’m not getting any video or OSD that means my FC is the problem? I’m just getting a black screen with no OSD. I have another copter that uses the same board. It has the same issue as well. They are both flycolor raptor s tower stacks
The easiest way to tell if the FC is the problem is to connect the video signal wire directly between the vTX and the camera.
Joshua Bardwell that’s exactly how I determined the problem lies with the FC. It uses a pass through function with the FC. Vtx plugs into it and then the camera plugs into it as well. I could always go the old fashioned way and connect them to the pdb and it should work fine. Thanks for the reply back!
Josh, do you have a link to that monitor you use? How do you like it?
+Alienfleet there is a link in the Cards (click the i icon in the upper right) but this exact monitor isn't sold any more as far as I can tell.
Thanks man, appreciate it.
