TBS UNIFY REPAIR | no output power
Vložit
- čas přidán 28. 08. 2024
- HI,
This is the repair of a UNIFY PRO vtx that suffered from a loss of power (vtx seems to work but at every output power level the range is zero).
It is a common issue with these video transmitters, with more reasons but the most obvious being powering it from 12v or LIPO voltage instead of 5v (there are 2 versions, one for 5v and one HV witch can take LIPO voltages with ease). Another reason can be damaged antenna or by powering it without an antenna that leads to too much current draw from the LDO.
PART : AP7365-WG-7
I hope i said it all, if not please ask in the comment section.
Thanks for watching.
This is amazing. This is way more technical and in depth than over 99% of other drone youtubers. Subbed. Love it.
I had this same problem (no video past 1 foot, even on 800mw) but I burned the pads off trying to fix it. I wish I would have seen this video a month ago. Thanks for putting this content out there!
i like ur english, it very clear
Best video tutorial ever it was so exact and easy to follow!
Hi brilliant instructions video the part no. For that LDO is it
VA7NA
damn thanks for this reapair video mate! i've been wonder why mine isn't giving me solid video and noticed it's not getting hot.
Thanks Dude, this video helped me repair a broken f3evo for my whoop. Except i don't have a heat gun and had to use my ts100 to solder
glad i could help :)
I love this channel. you def earned a sub. I love the "I'm not going to tell you the part number".....shows part number.
Lol thats just a part marking not actually part number ;)
Super, super useful! Thanks!
Hi Livyu. I like your repair videos.
I have 2 not functioning TBS unify HV race.
Unify #1 is completely not turning on if we plug in the battery. Led not turning on and the vtx is not heating up at all.
Unify #2 is almost working. Led is on, vtx heating up, but it's only transmit video on channel L4 (very poor video) and we cannot change channel whatsoever. No overheating LDO.
Do you have any idea what component(s) is broken or need to be replaced? TIA
Very nice job and clear explainations. Love it !
And your English is perfect. I understand all your words. And this is not always the case with american or english people ;)
Thats brilliant!! and difficult also risky bro....
another epic video...I'm so interested in how easy you make these repairs.. i will ask you only one question.. Where can I find these parts ? the resistors and LDO's and tiny processors.. ? thanks for the video's love this stuff..
Great video - you made it look easy!!!!
Very good video! I just had to fix a DVR that had one of these burnt from wrong voltage. I did it in a very ghetto way 😂 but I was lucky and it works. I will follow this way and get the right tools next time
I flew my quad for 3-4 minutes without an antenna. When I measure the VTX output set in 800 I get a reading of max 250. Is this a consequence of my accident? If so, do you think this fix will do? (I subscribed to your channel, your videos are excellent :)
Very nice repair work!
Great video quality and good soldering skills :)
Got to get me the same tools 😊
I ripped of this LDO by a cable strap. Even some pads are gone.
TBS told me the part number (ACE50936) but i was not able to buy it.
Where did you buy the LDO? Or did TBS gave you a different part number?
Good job, I have tbs pro v5 800mw like yours in this video when I plug my lipo it's work fine and I have a good image after 10-15s the tbs heat up and no more image I have to unplug the lipo, this happen after crash 😁 what is the problem?
Hi Livyu, thanks for your video, is it great. Do you have experience with 2.4 ghz 800mW Unify vtx(5V)??? I've got same problem in this vtx. Low power approximately 20mW. LDO is just marked ,, AGET,, What kind of LDO is there? Thanks :)
could you please tell us which kind of hot air gun are you using...!? Thanke you
Podrias hacer un video del vtx hv de tbs?
Muchas gracias por tu información pero no sé inglés y me entero de muy poco, gracias
Very nice job !
Awsome video! What is that little heat gun thing you are using? Got a link for that?
hello I want to get help on a subject. I used my ts5823L vtx transmitter without antenna and the device fell silent, which part needs to be replaced,
Very nice job !!
I detroyed the ufl pin do you know where we can solder the antenna by an other way because the pad for the little pin of the ufl has been ripped ?
I which you can help me
Do you maybe know what uC does Pro32 HV use and what modulator chip?
I dont have one right now at hand, and I could not find this anywhere
What camera do you use to record such good close ups?
Hi how to test if it is that part? I have video but very weak even on 800mw. Only like 1 or 2 meters
use a multimeter and check the output of that LDO i changed (you can see how at the end)
Livyu FPV thanks yes it have 0.02v so i have to replace it
Thanks!.. im gonna do this to with my two failed vtx!!!
The repair work you do. Did u teach yourself or do u have some kind of a electronic background from School?
50-50 :)
Livyu FPV thanks for the fast reply. I e been trying to teach myself anything on the repair side of things since getting into fpv. So I appreciate you and what you do so thank you
Thanks ! :) I am glad i can be of help
Very nice ! 👍
I have the pro hv 7-pin. My video looks gr8 until i power up my transmitter? When my TX is powered on the Unify showes horizontal lines in my video feed? My radio is the Taranis x-lite 2.4ghz. I don't understand why this is happening?? Thanks!!
Amazing. Thanks!
Hi friend, thank you for this video, I have The Unify HV version, what part would that be for me?
I am only getting 3.5v output on that ldo, at 500mw setting, does it mean it is broken? The range of my tbs vtx suddenly become weak, i am only getting maybe 20 meters and the video is gone. Thanks
Hi, I did the fix and it worked fine for about 3 flights until the LDO was broken again :( Replaced it again, and the same thing. Do you know why?
hello friend, my ts5823L transmitter ran without antenna and I think the device burned.I want to repair, please help, what should I do.
Why did you change that?
Livyu FPV , are both voltage regulators the same? The LEDs on 5v unify won't even come on. I'm sure I gave it 12v by accident..there is no obvious burns.
from what i remember they are different one 3.3v and one 4.2v
Super interesting... How do you manage to know that that ldo power the rf and the ather one powers other things??!!
well it was pretty simple, the led's were working (sign that the MCU works) and I could see video transmitted but at at a range of max 1 meter (sign that the RF transmitter IC was working) and i measured the output from the both regulators and one was outputting 3.4v and the other 0 so this is how I ended up with the conclusion
I also got the part number from TBS support. They didn't tell me not to post it... so I'm tempted to post it. Did they tell you not to?
not really, but its their product :)
kenkamm post please
AP7365-WG-7
0:36 whats the chip he is pointing on? pls reply
what kind of heat gun do you use---> which one do you recommend buying :) i've got way to many parts needing a repair :)
well ... its hard to recommend one :) one that is not too cheap but not too expensive? :) I use a TENMA one Iron/HeatGun have it for around 8 years now. But Weller is a great option if you can afford it :)
@@LivyuFPV Thank you very much! Your video is very useful.
I accidentally fried my video transmitter. I ordered a new part to replace it.But when I was shooting the old one, one track ( the third one, which is on the edge) came off along with my leg. Very sad.
Maybe you know where you need to solder this third leg to make everything work? Thank you in advance!
is Yu is your last name? lol is a Chinese last name . damn good video brother
Thanks! no, my name is Liviu (hard to pronounce in English so i wrote it Livyu)
Nice
I dont own a heat gun, but now I want one. Can you tell me what to look for when shopping for one?
man, you should look for a rework heat gun in your price range :) cheapest is around 100$ most expensive around
thousands so ... what you can afford is the right for you :) the cheapest entry level one i heard of is the Atten 8586
Thank you.
can i send you my tiny hawk 3 no power?
Super friend. link of the component that you have replaced?
Please ask the TBS support as I said in the video.
Would you be willing to fix mine if I paid you and shipped it?
Sorry man I do not offer repair services. I barely manage to make this videos(time) and the benefit when repairing this kind of gear is present only if you repair it, otherwise is it not worth it (cost wise)
Can i at least PLEASE buy the component of of you? A regulator blew out on my PDB and Im sure thats what blew out my VTX. Can I paypal you to drop one in the mail for me?
@@michaelaustin6000 sorry man but it is difficult... To know what is wrong with. Contact me over facebook and I will try to help you findnwhat part is wrong and i will give you the part number you need to order.
