Thank you!!! Input 2 wasn't working on my TV and a hard reset fixed it!
XxXDreamSeekerXxX how do u hard reset it
@@beastbett :52 second mark
thank you for pointing out the idea of doing a hard reset. I was getting frustrated and the idea didnt even cross my mind. once again, thank you
Thanks man I was so bummed when it stopped working. did the hard reset and now worked you are a God send
Man, you just saved me a crap load of money. The hdmi port just quit for some reason, I unplugged the tv, waited about a minute and now it works!!
this is the video i've been waiting for... thank you VERY much!!!!!!!
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
Thanks for the lesson brother.
proto718 no prob, I'll try to make more videos like this to help out.
Thank you for help .Did hard reset ,got HDMI back
Great exposition. Thanks a lot!!!
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 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
Thanks! Unplugged the TV and that did the trick!
My TV won't pick up any channel on regularly tv . Can you help me with it
It works for me now also
All i had to do was to drag out the power kables for 30 sec, Thanks man u saved my day

Hi bro ,
I have issue in my Epson projector , VGA , RCA working but both HDMI getting no signal ... Can you suggest some troubshooting ,
Your vids are great
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?.
For once a video that helps I’m liking this
Thank you so much I did the hard reset and it work perfectly!
How do u hard reset a TV
@@Lionixs1 by unplugging the power cord for the TV from your wall. Then wait 60 seconds before plugging it back in.
NICE post! I tried your link: "My TV repair tools I use..." but that site is down? Curious to know what Iron you used? Thank you!
Thank you! Hard reset worked. WHEW!!!
Thank you. I had no signal. But now All of my ports are working now.
thanks, you reminded me to do a hard b reset on my tv and that fixed my hdmi problems
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! Can I do this without removing the main board from the tv?
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 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.
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!
hello I would like to know I have a panasonic tc-p42c2 that works for a while the hdmi ports and the image stops working comes and goes that part could be the one that will be this morning
No signal. Then I reboot it. Tv keeps flashing with the picture. Then it goes back to no signal🤔
I have the same Problem with my monitor
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 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
OMG YOUR AN AMAZING HUMAN BEING❤️
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
Hey Tampa Tec! Do you do receiver diagnostics? I have a Sony STR-DN1080 that’s not working but it’s only 4 years old.
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
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!
I have a connection but lines show on my tv. Can you help with this? LG tv with a Samsung computer windows 10. I tried wireless but it only found each once and not again.
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.
Me i just repair my own is not working
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?
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.

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??
Awesome instructional videos! Question, I'm replacing the HDMI board on Vizio xvt373sv and having trouble disconnecting the "ribbon" wire harness connectors, any suggestion is welcome, thank you for your videos!
So did you fix it.. didnt see you turn the tv/hdmi?
Anyone have any ideas on image convergence when using HDMI?
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?
Tv flips through channels until u push in button for select HDMI aux pc. etc u hold it ok let it go it flips ?

Hello. ihave a vizio e60- c3 the problem is have 3 hdmi 1 and 3 works. number 2 doesnt works. how check the main board to repair this problem?
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?
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.
Thank you so much
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
I have a Vizio E422aw powers up, menus all work apps menu works but No Signal from HDMI INPUTS
i know same here i have a vizio not smart tv
I got a lg 32 not selecting any of the av inputs. the main logic board and av bord was replaced and still same problem...
Thank you!!!!!
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!
Hi i need help for i dvr ho that have the same problems there is no signal output
Your thoughts: I have a 75' (new) HDMI cable that when I test it on four different TV's it works perfectly. But, when I plug it into an HDMI input on my 55" Panasonic TV (2013 model) I have no signal. However the same HDMI input works with my ROKU device. The HDMI source is coming from a security system through a powered HDMI splitter. I'm at a loss.
Could be signal loss with the Panasonic TV. HDMI cables at that length tend to start getting iffy about signal strength. You really want to keep HDMI cable's as short as possible to avoid this issue. Or convert to SDI cable, but the requires multiple converters and cable and can get expensive.
Will this work on PS3 as well?
Please share which type of model Heat gun is used ,

Thanks bro your second tips it works thank you so much.
May I ask how durable are the HDMI port?
awesome, thanks :)
Thanks for your help. Tampatec, never thought of just having to update the tv itself. Really appreciate it.
Hi Paul,
When you say a cable can be bad, what causes a cable to go bad? If it's a bad connection caused by corrosion, can the connector be cleaned with contact cleaner?
Thanks a lot, Tom
Rather fatigue of contacts or bad manufacturing tolerances right at the get go.
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?
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?
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
Where can I find the hdmi chip for a Sony VPL VW270ES? Can’t find the chip neither a replacement board
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?
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?
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.
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
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?
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

@@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.
pls bro how to fix dreambox 800se no hdmi signal
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.
