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.
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?
My own problem is that when I plug DVD, blu ray player or even amazon fire it won't work but if I plug my hdmi camera or camera switcher to it, it works... Can you help please?
hi there. I have a Panasonic TX-40DX799B smart TV. The TV itself works but I cannot change the input source, access any of the smart TV menus, tv options menu etc. Any idea what this could be? is it worth replacing the main board? thanks
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 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
@@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!
I notice that you are "Tampa" tec. I'm close to Tampa, and just trying to figure out if my HDMI is worth fixing? I was thinking about doing it myself until..... You brought out the heat gun. Do repair shops fix these, or do you do repairs?
Yes, I'm in Tampa area. I worked at tv repair shop and best buy warehouse fixing TVs, also pinball and video arcade games repair. I fixed TVs for friends and family for free. You can find my email info on my UA-cam about page, I'll shoot you some easy tech tips that may help.
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?
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
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'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?
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.
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
Hi. I always enjoy your instructive videos. I have a HDMI problem however is there a way to test those connectors with the board unattached from the tv?
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 :)
I got a black screen without placing HDMI but when I do I have only Sound. I got a question does it True when you replacing HDMI from Cable TV to PS5 for example without turning off the TV it can cause problems like black screen? because I only did that then my problems begin
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.
Thanks for the heads up. I've been doing research for a HDMI signal problem on Mistubishi 65 inch dlp. It loses the signal and I have to exit and reselect HDMI input. After signal loss sometimes the HDMI input is not visible when attempting to reselect, only AV selection is shows on screen. You need to make repeated attempts before HDMI shows on screen. I know 2 owners who experience the same problem.
Thank you!!! We did a firmware update could not get the HDMI to work.........hard reset on our Samsung 8000 series built in 2013 and now it works great. thank you for your help.
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?.
working on an Insignia brand tv from the early 2010's I recently inherited. None of the HDMI ports work for any kind of video output from my laptop, and audio from playback device shuts off/tries to "transition" to the tv display with no sound.

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.

Hi Tampatec, Fire stick suddenly stopped working on my LG TV. Has only 1 HDMI port. Set top box from cable company works with this HDMI port. But Fire stick stopped working. The Amazon logo appears and then black screen. How do I fix it?
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?
Useful stuff !!!. Sorry to bother you "again". But in a few videos back I sent you a question to see if the power supply board EEPROMS are the same as the vizio TV you mentioned in that video. I'm trying to fix my Sony Blu-ray DVD Home Theater and I just can't seem to find the whole power supply board so I thought maybe I can just replace the burnt part but I don't know if the EEPROMS are the same or where I can purchase them for that matter. Anyway, anything you can help me with will be much appreciated. Thanks, and keep doing these videos they are very helpful. Sincerely; another enthusiast, amateur electronic repair man.
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?
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?
I have a Denon AVR-3310CI hooked up to a Epson 705HD projecor it worked fine for awhile and now it seems to have a signal loss no matter the HDMI input. It works and then losses the signal. Any advice would be much appreciated!
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.
@@TampaTec Hi, i have fallowing situation. My older TV in kids room have HDMI, and my IPTV and other recievers are connected to it, and they works perfectly fine. But when i connect PS4 Slim, it only gives sound with constant breaks, and video doesnt showing. Its black screen, there is no "no signal" message. I tried on my others TVs, PS4 working perfectly. I tried to lower resolusion of PS4 on other TVs and then connect on this one, still didnt solved problem, i tried to reset PS and make resolution lower, also not helping. I switched cables, and all other stuff. But my other players and IPTV reciever working perfectly with every cable, on every output/input, only PS is not working. Greetings from Bosnia, and keep with good work.
Just a tip...use liquid flux on your solder wick. It greatly improves the wicking action and reduces the amount of heat needed to do the job. Remember heat is the number one killer of otherwise working chips.
All my HDMI ports but one don't work. We just had a storm I'm guessing this is the cause??? This looks way put of my skill set how much would it cost to repair ports like these? Thanks
This is exactly the problem happen to me. It was a storm then the power went out. Since then, we have no signal... The calling cable company charged us $100 just to come check it out since we thought it their issue.
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. I leave it on for half hour then sometimes comes on then start working all day long when I turn it off the night time the next morning the same thing goes on again what do you think could be the problem?
I wonder if you can help. What is happening is all works good then no signal so I switch to other hdmi like xbox and it works than back to other hdmi what just lost signal and it works again for some time. Sometimes more sometimes less time. So switching to other hdmi always fix the problem temporarily. Thanks appreciate if you can say what you think. It's Sony Bravia
Hi Bro, this is very educative video we have here! Thank you ! I am from India! My Sony Bravia tv klv 40s-550A, HDMI ports not working after a lightening in my area, Apple TV and my cctv DVR which were connected to HDMI also broke. When I checked , the tv is working alright and other ports also working. The external input menu indicates that all the four HDMI ports are connected with devices, (no device is connected and ports are free) an arrow mark pointing outside from corresponding port. I am having fairly good knowledge of electronics as a technical person in maintenance of communication equipments, and little knowledge about TV. I appreciate your help in solving the problem. Sony service personnel suggested replacing main board which is fairly expensive as half the cost of TV. Looking forward to your suggestion. Thank you.
great video! i have a samsung tv (UN60J6200AFXZA) and a denon receiver (AVR-S510BT) and new monoprice HDMI cables sometimes shuts off for a second or two and then comes on this happens when i'm watching cable or roku how do i solve this issue? not sure if this matters, but i have another denon receiver (same model number) connected to an LG tv with no problems thanks in advance
Here's a problem I've had for weeks my computer works fine connected to my TV through HDMI however if I try to connect it through an HDMI pass-through on the other side of the living room to the same TV after the post screen the computer makes a rubbing sound then stalls and does not boot the windows. My laptop will work fine through the same port however in safe mode

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?
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!

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. My TV has the one with two HDMI. But is more expensive than the one with three HDMI. Is there a problem if i buy the less expensive board which comes with three instead of two hdmi ports, that my TV originally came with??
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
On my LG 47" tv the side HMDI, components and USB work but everything in the back doesn't (3 HDMI ports, component ports, coaxial cable connection) is it better to buy a new board or is there a fix for this? any help is much appreciated.
Hi Tampatec, Fire stick suddenly stopped working on my LG TV. Has only 1 HDMI port. Set top box from cable company works with this HDMI port. But Fire stick stopped working. The Amazon logo appears and then black screen. How do I fix it?
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?
Useful stuff !!!.
Sorry to bother you "again". But in a few videos back I sent you a question to see if the power supply board EEPROMS are the same as the vizio TV you mentioned in that video. I'm trying to fix my Sony Blu-ray DVD Home Theater and I just can't seem to find the whole power supply board so I thought maybe I can just replace the burnt part but I don't know if the EEPROMS are the same or where I can purchase them for that matter. Anyway, anything you can help me with will be much appreciated. Thanks, and keep doing these videos they are very helpful. Sincerely; another enthusiast, amateur electronic repair man.

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?
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?
Will this work on PS3 as well?
I have a Denon AVR-3310CI hooked up to a Epson 705HD projecor it worked fine for awhile and now it seems to have a signal loss no matter the HDMI input. It works and then losses the signal.
Any advice would be much appreciated!
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.

CABLES from you soon with the same thing happened with a HDMI
@@TampaTec Hi, i have fallowing situation.
My older TV in kids room have HDMI, and my IPTV and other recievers are connected to it, and they works perfectly fine.
But when i connect PS4 Slim, it only gives sound with constant breaks, and video doesnt showing. Its black screen, there
is no "no signal" message. I tried on my others TVs, PS4 working perfectly. I tried to lower resolusion of PS4 on other TVs and then connect
on this one, still didnt solved problem, i tried to reset PS and make resolution lower, also not helping.
I switched cables, and all other stuff. But my other players and IPTV reciever working perfectly with every cable, on every output/input,
only PS is not working.

Just a tip...use liquid flux on your solder wick. It greatly improves the wicking action and reduces the amount of heat needed to do the job. Remember heat is the number one killer of otherwise working chips.
All my HDMI ports but one don't work. We just had a storm I'm guessing this is the cause??? This looks way put of my skill set how much would it cost to repair ports like these? Thanks
This is exactly the problem happen to me. It was a storm then the power went out. Since then, we have no signal... The calling cable company charged us $100 just to come check it out since we thought it their issue.
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. I leave it on for half hour then sometimes comes on then start working all day long when I turn it off the night time the next morning the same thing goes on again what do you think could be the problem?
thank you something so simple happy holidays
I wonder if you can help. What is happening is all works good then no signal so I switch to other hdmi like xbox and it works than back to other hdmi what just lost signal and it works again for some time. Sometimes more sometimes less time. So switching to other hdmi always fix the problem temporarily. Thanks appreciate if you can say what you think. It's Sony Bravia
Hi Bro, this is very educative video we have here! Thank you ! I am from India!
My Sony Bravia tv klv 40s-550A, HDMI ports not working after a lightening in my area, Apple TV and my cctv DVR which were connected to HDMI also broke. When I checked , the tv is working alright and other ports also working. The external input menu indicates that all the four HDMI ports are connected with devices, (no device is connected and ports are free) an arrow mark pointing outside from corresponding port. I am having fairly good knowledge of electronics as a technical person in maintenance of communication equipments, and little knowledge about TV. I appreciate your help in solving the problem. Sony service personnel suggested replacing main board which is fairly expensive as half the cost of TV. Looking forward to your suggestion. Thank you.

Here's a problem I've had for weeks my computer works fine connected to my TV through HDMI however if I try to connect it through an HDMI pass-through on the other side of the living room to the same TV after the post screen the computer makes a rubbing sound then stalls and does not boot the windows. My laptop will work fine through the same port however in safe mode
Thank you so much! I didn't know about the hard reset and it fixed my TV. I knew it was still working because I could cast to it, but none of the HDMI ports worked.

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?
