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
Where can I find the hdmi chip for a Sony VPL VW270ES? Can’t find the chip neither a replacement board
Thanks man I was so bummed when it stopped working. did the hard reset and now worked you are a God send
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
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
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!!
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
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.
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.
Thank you. I had no signal. But now All of my ports are working now.
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
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.
To all ppl who skip to 7:30 i suggest watch whole vid to fix ur problem
Hi tampatec i am getting a issue with hdmi port going on then off every few minutes any idea what that could be? regards
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
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.
Thanks for your help. Tampatec, never thought of just having to update the tv itself. Really appreciate it.
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?
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
your the coolest TH-camR ever!!!!!!
RockstarGamers thanks

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.
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.
this is the video i've been waiting for... thank you VERY much!!!!!!!
THANK YOU!!! The hard reset worked! You're the best
Thanks for the lesson brother.
proto718 no prob, I'll try to make more videos like this to help out.
All i had to do was to drag out the power kables for 30 sec, Thanks man u saved my day
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?
i baked my motherboard in the oven for 10 mins at 375 degrees and now mine works great
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.
thank you something so simple happy holidays
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 :)
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?
Please share which type of model Heat gun is used ,
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
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?
Thank you for help .Did hard reset ,got HDMI back
ever replace the IC then get image back on all ports but no sound?
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 TH-cam about page, I'll shoot you some easy tech tips that may help.
Is it work for AV receiver..?
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
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.
M. A. J eeproms are made for certain boards. eeprom are not universal.
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
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!

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. Should I just replace the whole board since all 4 HDMI ports are bad, or try to locate the fault on the board? Any help would be appreciated. TIA ☮
Yes, seems the main video board is bad. Get TV boards for TV Parts today or ShopJimmy website.

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?

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.

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

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

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 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?
Why does my vizio 65 inch when i first turn it on after it not being on all night. It says no signal on all hdmi ports I have to restart the tv in the settings. And after I do that it will work fine. I just don't understand why it won't work when it's off all night till the next day.

I know the HDMI ports send power and it does produce a pretty good image. It is just that it, requires power cycling for the hdmi signal to be recognized and not get a blue screen.

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!
Is there a way to force the software or hardware update? I tried to force install from a USB drive and it didn't work because the system was already updated?
The reason I say that is because the HDMI works today but tomorrow it stops working (which I suppose is an HDMI problem), which might have been caused by a failed software update
Same problem, fixed in factory reset afew weeks only red light and not power on.
