Hello good video. My tv there is no signal from HDMI ports. The first time I had no signal I removed the power cable and reconnected it back and it came back to normal. After that I had the same problem again and several times over and over now I can only use AVI connection. I was checking the msd capacitors around the IC and I found 4 bad ones but I am not sure if I was testing the capacitors right. Do you normally check those capacitors around the IC?.

Question, I'm trying to replace the main lojic board on a Zenith because of HDMI no signal. model Z37LC6D-UK, went to shopjimmy there are two versions one with three HDMI one with two HDMI.

thanks for the video. I'm having issue with my Sony AV Receiver, HDMI Port 1 not working but 2 and 3 works. So I guess it's not the chip problem and like you said if HDMI port is loose re-solder it but mine looks perfect. Should I get my HDMI port replaced?
PS : I did some re-soldering and I got picture but was noisy. What's your opinion
Tampatec, thank so much for these videos. I have a problem with my LG 47LM6700. one time it stopped turning on at all no red light. I switched both PSU and Logic board then the TV has red light working and switches on for 3 seconds. I see the logo then the back lights turn off. I did a flashlight test in a dark room and there is picture. Please help me with the next step. PSU does not seem to have blown capacitors and no brown spots on Logic board.
Great exposition. Thanks a lot!!!
Hi, I have 2 tvs, both stopped working from the same bad hdmi cable. The tvs do nothing,1 of them smoked from the back of the set. Any help would be appreciated.
I still have a problem, so when I plug my Xbox HDMI into the TV and turn both on it says:No Signal - HDMI Check if the source device is connected and powered on. Or press the INPUT button to select the input for the source device.and that's what it displays BUT when I hit the TV slightly it loads the xbox home screen but any slight movement of the TV it goes back to the no signal screen, should I take it somewhere or should I be able to fix it myself?
Thanks for the info, got a goodmans 19" that none of the inputs (hdmi, av or svideo) work on. Tried everything except fw update because I can't find one or how to reset.
Hoping it's a easy fix but doubtful
Hi from my laptop motherboard i have signal to main display but not to hdmi. What i want is to manage work only with external monitor , is it possible to give like 5v signal to one of the pins of hdmi in order to switch on the external monitor?

Hi! Can I do this without removing the main board from the tv?
Question: All my HDMI ports do not work and my RCA ports as well. However, my RGB port works. Should I replace the whole board?........Thank You!
Thanks so much! I pursued the baking route, reinstalled, and hdmi ports back working. Super!
Hi, can you expand on what you did? Did you really bake the board in the oven? If so, for how long and at what temperature? Is it still working?
@@nathaniel781 I did really bake the board in the oven as prescribed. The baking time was about 10 minutes at about 250 degrees (can't recall specifically) and kept an eye on it to avoid "melting the board". Regretfully, after a few months of returned operation, the black screen returned and I ended up just replacing the ten year old TV.
@@tcong9616 thank you for replying! My no signal issue happened about 2 years ago and I sent the board off to get fixed but tonight it randomly just went out again (it was working this morning). Given how old the TV is and the odds of failure again it's not worth sending out to have it fixed again but if it's something I can try myself then I may give it a go. Thanks again for your help!
@@tcong9616 did you add flux, though? Or solder paste?
@@dushk0 neither. Just baked
I have a Yamaha rx-a730 receiver that a lightning strike followed the dish receiver HDMI into an input. Everything works fine but the HDMI side of things. Any suggestions or lost cause? Love that receiver and can't afford another.

I'm having problems with my Insignia NS-32E320A13 TV because it says "not supported" for every cable box I connect to the tv. The boxes works with other tvs. And it doesn't give me possibility for changing the channel system (PAL/SECAM), it just show NTSC which is not supported in Mozambique (Africa). Is there any help?
THANK YOU!!! The hard reset worked! You're the best
thank you something so simple happy holidays
Hi. I have a vizio xvt553sv. That reads no signal to all port connections.( hdmi, vga, usb, etc.) So I went ahead and bought a main board with all the port connections and still getting no signal logo on screen. I noticed on the led driver. There is a orange led blinking on it. Could it be my led driver or connections board. I don't want to spend on unnecessary boards. Thank you
All i had to do was to drag out the power kables for 30 sec, Thanks man u saved my day
I have a 52LG60-AU Scarlet when i plug something in the HDMI port like the playstaytion i get a picture but theres allot of static lines and when i plug the pc in the pc port every thing is ok what could it be i want to change the main board but cant find any on EBAY AMAZON no luck:(

My TV won't pick up any channel on regularly tv . Can you help me with it
It works for me now also
I had a channel device that was mistakenly connected to the wrong power source on the television. After that, all the TVs that I connected the hdmi had the same defect (in all the hdmi inputs). Tvs almost do not work when plugging a device into hdmi, however, it works when the device has some kind of power source. Do you know what it could be?
Hi, I have a VIZIO M-Series 80" Class Ultra HD Full-Array LED Smart TV | M80-C3 for 1 year. All HDMI ports are not responding to the incoming signals. If any of the HDMI port is inserted the remote control loses all functions. So I can only watch local TV station channels. Had tried everything the Vizio support recommended but no result. Any ideas what is going on and how to fix it? Thanks. Allen

Hi there I currently have a Sony Bravia tv and it will work for tv somewhat but with PC how do I go about fixing that
On my older LG 46LD550, none of the inputs work. HDMI, USB, etc. When testing voltages to Logic board, 3.5V is only 3.41V with cable plugged in or not. Is this the voltage supply to inputs? Would this low voltage cause the issue? Thank you for any help. This site is fantastic, it's great of you to share your knowledge.
Thanks so much for this video....I have a LG 3D LED tv that's aprx 10yrs old now and they still sell for $1500+. The main boards are extremely hard to find. I'm going to try this on one or all the boards I have to try to get this tv working again. The picture is better on it than my 55" LED tv that's less than a year old. You may have helped me revive my 3D tv again! Thanks again
Hi i need help for i dvr ho that have the same problems there is no signal output
Hi, I was getting a no signal prompt on my Insignia 55 inch NS-55DF710NA19. I saw your video and figured a main board. Now the tv is black. I can see the screen with a flashlight and hear sound. Is this another problem? Thanks
lightning struck cable box outside...hdmi ports stopped working on both Samsung TVs. RCA jacks still work. lost volume completely on 1 TV. any cheap way i can fix myself?
thanks so much ; I was already getting in the mindset to sober into my dvr security system's cdmi plug - fortunately it worked after I unplugged it - and waited (as u suggested) what a relief - because I destroy everything, not really but kinda true ; u saved the day - again thanks :)
2 year old 36" Samsung Smart TV both HDMI ports & even the AV inlet plugs don't work, is it worth fixing or but a new TV?
You mentioned you new a repairman that had advanced equipment for board troubleshooting but we didn't see the link post at the end of this video. Could you post that link please? Thanks.
For once a video that helps I’m liking this
Great information. My 4K LG tv of four years start acting up. Keep going out on HDMI. I tried the other port and it does similarly. I replace the HDMI Cable problem persisted. I did a test and it said all connections are good. I tried to eliminate all likely possibilities by going to Roku similar problem, now I am thinking of replacing the main board. The tv does work perfectly for a while at times, working presently but will start malfunctioning again as it did before. How do I do a firmware update?
Panasonic TC-L58E60 HDMI ports stopped working. Reset tv to factory defaults...how do I fix them? I can't find the replacement part online for the life of me! Is there any adapter/converter I can use by plugging something into AV1 or the USB port so I can still hook up HDMI cables to my tv via usb/AV1? Please help me fix my tv!
Thank you for the great video. At 1:37 you mention that if you plugin the RCA connections and it works but the HDMI connections don't then it could be fixed by updating the software . My 42LC2D tv displays "no signal" on both the RCA connections and HDMI connections, the only thing that works is the antenna. What could this mean? I'm trying to get any of the connections working but preferably the HDMI. Thank you
thanks, you reminded me to do a hard b reset on my tv and that fixed my hdmi problems
Good morning. My Onkyo Receiver takes about 20 minutes to provide signal to the screen. It seems that when I turn it on, it needs to warm up before it starts working. Any idea what could be done to correct this?
I think u have great info but not seeing my TV's issues I posted a video hoping to find help have any suggestions would be great
Thank you! Hard reset worked. WHEW!!!
I have a quick question that 'm having lots pf trouble with. I have a t.v. that I am currently trying to fix and I am not an experienced tech, I've looked at my power board and found the key or compass I guess is what you would call it. Anyways I've tested my main plug where it show voltages for standby and other things, but there is something that says DEV 5V, and that is my issue. It reads at 2.8 volts and if this is the problem I have no idea where this is located. The tv is a Samsung LN40B500P3F. I've researched and researched and just cant find my next step, any help at all would be appreciated. Thank-you and have a great day.
great video!

Hi tampatec i am getting a issue with hdmi port going on then off every few minutes any idea what that could be? regards
Great video. A lightning strike took out my modem, cable box, and all 4 HDMIs on my Samsung TV. I have not opened it up yet, but based on this, would your assumption be a bad IC? Is a new main board the way to go in your opinion?
I have 3 hdmi ports on my board, all of them give sound but not image, is there any fix?
I'm trying to fix a TV for a lady I go to church with. It is a Toshiba 32L220U19 32" TV. She said she was watching TV when it suddenly went to a screen full of static. I checked it out, it will not receive any channels through the tuner. I can get a picture just fine through the HDMI input. Also, the audio is not working through the speakers, but works through the headphone jack. Is there a simple fix for this TV or will this require the replacement of the main board?
what up, Tampa Tech? Here's my dilemma, I hope you can help me; I have a Mitsubishi WD 65 738 DLP 3D TV with working RCA Jack's, but all 3 HDMI ports all stopped working recently! Am I looking at a logic board fix? How much should I expect to pay for such said fix? My set is 5 yrs old and I just replaced the lamp in it this month. is it worth a fix, or should I just invest in a 4k and hang it on the wall? Thanks
I just bought the 40" samsung series-5 j5100 tv and tried to connect it to my computer with HDMI cable but it shows "No signal". The strangest things are,
1. I connected my pc same way with another Singer 32" tv and it worked fine but the screen goes on and off but it was working merely.
2. I connected my laptop same way and it worked but the screen goes on and off. Again it was working merely.
But for this new tv, it can't even connect. Is there any solution?
Please share which type of model Heat gun is used ,

Hi, Please help. Both my TVs are not working now. One stoped working after connecting a Sunnzo box to it. So two days later, I tried to use the Sunnzo box on a different TV, now that one is not working. They both say "HDMI not connected". What could that external box have in it that would do this?

My Polaroid TV blew screens coming on and say no signal so I play with the input for 10or15 times still nothing then turn the TV on and off and on and off for several time and still nothing.

So did you fix it.. didnt see you turn the tv/hdmi?

Hi, I have telsa style android car radio. I have problem reverse camera no signal. What is problem?
Hi Paul, My LG TV from 2010 seems to have the same issue for almost 3 months, what I tried:
- I have used a hair heater to identify from where the problem come from: 5 minutes on the chip and the TV comme back to life for 7 days And the solution is temporary like you said because the issue have reoccured.
- So I tried your solution and I resoldered the IC like your video but nothing happens. So I tried to reheat the IC with the hair heater and it worked like a charm. I have tried to resolder maybe 4 times the IC with good purchases and aterials but it seems that only the reheat of the chip make the IC reworking.
Do you have an idea or something else? Thank a lot for all your videos and help!
