- Hi, this video shows you how to fix a broken LG TV using a HEAT Gun. The HDMI Main board had failed so you could not connect any HDMI leads to the TV as it showed no signal. By using heat from a hot air heat gun it has fixed the faulty HDMI board.
Please make sure you unplug the TV from the electric supply and fully understand the dangers of working with electric and electronics before opening up a TV.

I tried this just now and also worked first try,was doubtful at first but gave it a go since its already broken and it actually worked with no damage to the T.V set.Thanks!!!
I have tried maaaany tutorials without success... this one was the ONLY ONE that WORKED!!!
Very seldom do I find a RUclips “fix” that actually works. This didn’t work the first time. I figured I’d be buying a new board, so I gave it another dose of heat. 3 min on low, 1 min on high. I was stunned that it ACTUALLY WORKED! If it goes out again though, I’ll prob just buy a new set. They’re really cheap these days. Thanks Mate!
This is my solution. Suddenly all of my HDMI ports from an 50 inch LG Tv stopped working. I've watched a lot of this videos. My HDMI ports were listed on the menu (that mean that they have power) but always showed NO SIGNAL. I've tried to use this method but decided to follow a youtube user advice, bought the chip that is responsible for HDMI ports (2 USD on ebay) and found a profissional that changed the chip on the board (a TV repair profissional) and voila...it now works. This is my advice. Change the chip.
It worked for me today. I can't believe it. Haven't used this set in 3 yrs.. Thank you.. Will look to install a fan to keep the heat down on the board.
My Panasonic 3D TV (TX-L37etv5B) packed up and the dealer wanted £195 ($250) to replace the main board. I bought a new TV, but with nothing to lose I applied the heat gun treatment to the board and it's now working. Brilliant!
Brilliant! My TV, a 10 year old LG 42LE5500 failed last night and I just tried this today with great success. FWIW, I have a lower power heat gun so I increased the time a good bit and measured the temperature with an IR thermometer to make sure it wasn't getting too hot. I had a small scare when reassembling and the TV didn't start up properly, but quickly realized the one of the ribbon cables wasn't inserted fully. After replacing the connector the TV works as well as it did when new.
In case this is helpful, the peak temperature measured at just barely 300 degrees Fahrenheit. Also, there were no obvious issues with any of the components .
This is the most ridiculous solution I have ever heard of to fix such an expensive piece of equipment. however, with my television no longer under warranty, I decided to try it. MENARDS has a heat gun for $15.00.
$1500 tv 50" LG Plasma and a $15.00 solution.
WOW ! ! !
THANK YOU !!!
I really didn't think that was going to work, but it did. !!AMAZING!!
Ha. After two weeks of frustration and troubleshooting and about to pay $150 to send board in for repair on my LG 55lv5500 I tried this and it fixed my tv. Thanks for the video.
It worked!!! I did the hair dryer job and it worked today, 02/04/2021. Guys, I have a 42 inch LG LE5500 from 2010. All hdmi ports stopped working, so I disassembled and warmed up first for 1 minute and nothing. So I did it for 2 minutes and it came back ... but a little while it stopped again..then I did it for 2 more minutes and it came back. I tested it in the morning and now at lunch it was working ... well, the thing is, it worked. Tks for the advice and money saved
Just tried it this morning. Worked well. Used a dual temperature heat gun on the high setting.
So the first time I did this I was scared of hurting something and didn't hear it up much and it didn't work. Second time I cranked the heat and used your 2 min and 1 min suggestion and it worked perfect
Greetings from Mexico it really worked for me I just put the heat gun like 2 minutes like 15cm away from the board and I connected again an my TV. Ow is working again, I had an issue with My hdmi ports. Thank you
On my television also functioned this process !! Thanks a lot!!!
Wow....Good idea, worked as advertised. It might last a long time or problem might come back. Thanks. Vizio model M470NV
This worked on my Visio, great video. If it doesn't work the first time, let the board heat up more
Hello, nice video. How about the MSD capacitors around the IC? Do you check those capacitors as well?
Just tried and worke 100%. Thanks mate.
Big Thanx to u! Tried and worked. Saved a lot of money
I saw this and was tempted to do it but it says under the video "shop for hdmi TV replacements" and it shows a hdmi to dvi, so will the dvi still work if the hdmis don't? I'm not really a tech savy
That was petty coo! Just picked up a "hand me down" from my buddy,(dynex dx-40l150a11) cause he upgraded so he was gonna leave "curb side" cause only the RCA's work he said. I hope this works😊.
It worked on my 15-year-old Sony TV. Brilliant. Thanks, Mate.
Fiz na minha tv e deu super certo Parabéns LG 42Le5500
Parabéns, obrigado pela ajuda, abraços.
Wow. I better try this. I'll give an update. Love it.
obrigado brou.....economizei com os seus ensinamentos....JOÃO CARLOS - SÃO PAULO / BRASIL
Dude, I just tried this and it worked!!! I couldn't believe it. Thanks for posting
James Williams What temperature do you put the heat on in the oven?
My Kitchen Tv is LG 42LA640S this method fixed any problem Thanks
I repaired an LG plasma 65 in with no video it started when the HDMI not working then a year later the video stopped . REflowed LG XD chip fixed everything.
this actually worked! thanks buddy, you saved me a lot of money!
Hi vince, Ive been fixing gpus and chips for years by heating up method. Let me clear something to everyone, that the heat wont solder back the joints accurately it might do but at high temp you will cause more damage to other components if the process repeated excessively.
In fact the heat will just re arrange the chip layers for some time until they will come back to original layout over time this due to heat-cold exposure, So if you need to longer the period of the solution, you must cool down the chip with additional cooling solution, like adding fans or something else. Constant cooling will prevent the chip from having heat changes while its on operation.
In your case you've got a usb power TV, therefore you can DIY a small 5v fan on the chip ( make sure to identify the over heated chip ) and power it up from the TV USB, so it will be on and off by the TV.
Good luck
Hi, thanks for the information. I wonder if a metal heat sink was stuck onto the chip if that would be enough to keep it cool to make it last longer rather than the USB fan?
Thanks Vince
+My Mate VINCE well remember that the chip is in its final lifespan, so any sort of heat would eventually turn it into a failure, and then you have to repeat the process all over,
Regarding the heatsink method I wouldn't advise it, the reason heatsinks will only dissipate part of the heat unless you will use a pretty big one also the ambient temperature is crucial in this method, so if your TV will be in a super cool area then it might do the trick, otherwise it will be useless.
But with the fan it always keep the chip at low temp and ignores the ambient effect, still you can try the heatsink and see the result.
Cheers
Thank you, very informative, thanks for taking the time to reply.
+My Mate VINCE my pleasure
Hey Vince I love you man!😚❤😚
incroyable ce marche merci beaucoup !!!!!!!!
Interesting. Good video.
how long did it work after this heat repair trick?
Hello friend, I see you did this almost a month ago. Is the tv still functioning?
I'm in the exact same situation, except mine likes to shut off randomly. Hoping to find a cheap fix before I give in and order a new board.
Thanks from the USA!
Would this work on a monitor that is not working? If I don't have a heat gun can I use a hair dryer for similar affect?
This seems too good to be true. I might have to try this on my Samsung. It's just over 5 years old but one HDMI port no longer works at all and the the other works but has speckly green dots all over the screen which get worse before it reports no signal. Worth a try?
What is the temp setting on the gun you used - I'm guessing 400° ?
Than you very much.My TV LG is working again.
I just did this today, worked perfect. Thanks
Hi Heath Jones, after fixing your tv, does it still work?
Maricar Ga yes it does. I figured it was garbage so why not try. I tried, it worked and is still working.
This was the second time I've had to repair it. I got purple ghostly lines in it before and had to resolder a couple other boards. LG really needs to work on its soldering process.
thanks. i manage to fix mine.
Hi Vince, thanks for the repair videos. I just posted a video about repairing HDMI ports with heat (like what you did here) in case you are curious. I would recommend that you use flux next time you need to reflow the chip.
Would you say a hair dryer might suffice? I don’t own a heat gun. Also on my LG tv the ports are on the side and have disconnected from the board, do you know if the feet on the HDMI ports themselves need to be soldered or can they just be glued back in position? Many thanks!
Hello ! Thank you Im doing it but my heat gun is 300W , how long and at which distance would you do it ? Thanks
worked perfectly for now, will be monitoring in the next few days.
Thank you very much...my hdmi working again.
How long did this work? Is it still working? I'm so cheap and I love fixing stuff.
good job man , i'm gonna try it
Can I make use 65 insh display board for 50 insh tv that has the same cable port ?
hello i have lg le7500 and it just happened yesterday to me...if i want to replace this mainboard do i have to find the exact board from 7500 model somewhere or any lg 5500 or 8500 wilk work with this tv model? thanks
THANK YOU SO MUCH!! Did it with LG Blu Ray Home Theatre receiver and it works! Amazing! :-)
Классное видео!
Could I do this with a board from a laptop? My hdmi randomly stopped working.
Can I use a docking station instead and plug to the TV USB port?
I watched the video, decided taking the tv apart was above my pay grade. I improvised and applied direct heat via my blowdryer. It worked! I can't believe it!
Wonder if this would work without taking the tv apart and just heat up the bad hdmi port from the outisde
Ended up tossing mine in the oven (400F for 10 minutes) and it worked after that.. Heat's great for the short term but you likely won't get more than a couple months out of it, before needing to do it again. The solder on LG's boards is less than ideal, you'll likely need a repair shop eventually when you get tired of baking it. The smell from it is basically the smell of the solder, anyone who'd done that sort of repair work is likely familiar with it but it's not real bad. My TV is a 47LX6500, I wouldn't have even repaired it if it wasn't so impossible to find working 3D HDTVs now.
id try updating first as sumtimes software can mess up specialy smart tvs ie bad updates ect
Just seen this and decided to try it and it works. Thank u so much. An amazing video that really works.
Well done and thank u for posting
i try with a toast and oven, the tv was with a bad screen image i fix that but i still have no hdmi video and no sound the tv work with VA Connection but no sound i use for the xbox 360 and with a rca cable i can use the sound from the xbox to a house music stereo in the aux
I put mine in the oven on 250 for 10 mins and it works workderful now
make sure its not metal ure restin g board and heat the bottom gently then increase heat a then gently let it heat down or if its rushed it will crack solder leath 25mins or if moved it will go wrong turn over then heat the frount gently heat up to max temp circulation method as can warp board gently cool down or it will csause cracks in solder
Thanks. Works fine.
?? merci !!!!
Heat on an LG tv fixes a lot of the problems, as the biggest manufacturing flaw in those is solder joints, particularly on processors. they are very shitty cold joints. I made a shit ton of money and continue to do so on heat treating and reflowing processors on LG tv boards. Buy em cheap, cook em, and sell em high.
Good video. What I like to know is if it's works after heating is this a temporary or permanent fix???.
i baked my motherboard in the oven for 10 mins at 375 degrees and now mine works great
Will it works with a hair potent dryer?
Bro after heating it should be cooled?
Heated over a hot pan for like 20 seconds each side and worked lol
What does he mean by *handshake?*
Holy sh#t! It worked!! Thanks for the great video, fixed my son's Sceptre TV!
Hey Vince, Can you give us an update on your LG TV? It's been well over a year and I'm wondering how things are going after you've done this to the main board. Have you had to remove the main board again to heat it up, and if so how many more times since then? Are you still using this LG TV or did you put aside or retired it? Thanks!
Hi, it is still in use in my daughters bedroom but I now use the VGA port on the back (sometimes called PC) for the HDMI inputs by using a converter. From memory the fix lasted around 3 months and then I tried it again and it only lasted days. I got a HDMI to VGA adapter and also a HDMI switch and now the TV works perfectly again. It is still 1080p but the picture is analog so not quite as clear as digital but most people wouldn't be able to tell the difference. The 2 parts only cost £10-£15 and it is a better fix. See this video to see what I have done :-) ruclips.net/video/W-MR1UrHaMc/видео.html
So some moisture got in there and caused a micro-short, I would guess. Gonna try this on my faulty DVD/Home theater system that won't "hear" TV input. Will update.
This dose work but you only need to heat up the flat chip at 5:11. Its similar to the playstation heating trick. It is possible to do it without taking the board off. RUclips is awesome! More permanent fix would be to apply a cooling fin or something to keep the heat down on that chip or board.
i had a samsung tv with the same fault
which VGA to HDMI converter did you buy. can you find a similar one on Amazon and send a link
This is the one I bought from eBay so you should be able to find something similar in Amazon www.ebay.co.uk/itm/HDMI-to-VGA-RGB-Video-Audio-Cable-Converter-Adapter-Lead-For-XBOX-PC-HDTV-PS3-TV-/221931671457?hash=item33ac288fa1:g:T2MAAOSwo0JWOaIb
i have the same problem but the satellite receive HDmi is not working not the TV
Is this because manufacturers have to use lead-free solder which is prone to breaking contact? Heat gun would melt it again. A Mac repair guy told me that..
I just got a HDMI to RGB converter.. That worked but now the mother board has a bad solder and is stuck on start up.. I'll try the oven trick next time everyone in the house is gone.. Hopefully it'll fix both problems.. 👍
my tv is not working any advice
Hello how many watts is your heat gun ?
Does anyone know where I could buy the HDMI board..... Every online store I tried it is out of stock...
Model Number: 47LK520-UA
Mfg: LG
put the whole motherboard to ELECTRIC oven for 200 celcius for 10 minutes. Allow to cool down completely and voila.
So is your tv still working?
Tysm
Well if you don’t have a standby light try plugging in your hdmi cable
Dear Vince,
How can we watch different channels in different rooms from one set top box/one source???
Hi, I don't think you can unless you have a separate set top box but normally (in the U.K) you have to pay for a second set top box per month.
Thanks for the reply.
The problem is the LG XD chip. Not the HDMI IC. I had replaced IC with no fix. Then properly reflowed the XD chip after removing heat sink. Repaired. Tested.
So NOT the HDMI IC or ports but rather main IC.
Super !!!!
Can i use an air dryer
Yes. I have fixed Xboxes and lots of graphic cards for computers with a hair dryer.
Thanks. Now I have a working TV that I got for nothing from a skip.
Gotta say I was skeptical but this actually worked on a Panasonic I have.
I have a plasma doing the same thing both HDMI ports not working. Did your tv last long?
Would this work on a Xbox one port?
I heard this fix usually only works for a few hours.
how long did the fix last?
Si podía te ponía mil likes, gracias.. if i could i would give you a thousand likes, thanks vince
projector hdmi not working videos please
I don't have a LG tv but Hey Vince I love you man!
i done this on my xbox one hdmi kept getting no signal done this an it worked guys
What part of the motherboard did you heat up on the xbox one
i fixed my hdmi port on my tv with duct tape i duct taped the hdmi wire to the back of the tv this keeps the hdmi cable in teh correct position so the port works properly i watched a movie it works very well no problems problem solved
