• Repair An LG Televisio...
on how to fix an LG LCD TV with video or other mainboard issues, I gave it a shot myself and documented and it works!
WORKS !! - SEPTEMBER 2018 procedure. Followed the process line-by-line and now my 55" LG "LW" series 3D HDTV is reborn !! The smell from the baking lingered for a day but it is a small price to pay for fixing a $1400 TV for FREE !! Thanks for posting
AWESOME! Mine is STILL working perfectly also! Thank you for the feedback. :)
I found a 65" LG TV on the street with a note " Audio Not working". I brought it home, removed the main board and put it in the Oven at 200 for 10 mins . Put the board back and AUDIO started working again. IT WORKS :) and now i have a spare TV
I've recently fixed ours using a variation of this method. I didn't like the idea of heating the whole board, so I removed the heatsink, masked the surrounding components using foil and Kapton tape, and then suspended a 50W G10 halogen lamp about 1cm above the CPU, with a layer of foil underneath the board. I monitored the temperature using an oven thermometer to ensure that it reached 200 degC (392 degF) and maintained this temperature for about 12 minutes. I had a used eBay replacement board on order, so I had nothing to lose, but was very happy to find that it worked. It's only been about 12 days, but it's still working fine.
I have not tested the replacement board yet, but it's good to have it as insurance.
I’ve applied this fix 4 times so far, about once a year, and it has worked every time. Thanks for the weird fix!
Just to confirm it worked on my 55 LG, it lasted 8 months first time around, now re-baking. Came to read if anybody done it a second time, was glad to read even 5 times and it works lol :). Thanks a lot for this video!
I've baked mine 4 times now. Still works
Aug. 2019 - Now my third time baking the LG motherboard and the picture is still incredible. Baked it the first time in Oct. 2015, second time was Dec. 2018...so I have essentially got 4 years out of this process. My tv was of no use when this first happened and I was worried but gave it a shot...so happy I was willing to try this "home remedy". If your tv is now in a useless condition because of this problem (hdmi not working)...go for it!!!
Dec. 2018 About to do my LG motherboard for the second time...definitely works!!! My LG 55 inch first went down in Oct. 2015 for the first time and I got just over three years on the first bake, so here we go again. The tv is in perfect condition and the picture is still great...what a $$$ saver...awesome!
3 years, Awesome! I hope to get as lucky!
I did this last night. do it at 392 F (200 C) for 10 minutes. let it cool for 30 minutes with the oven off and oven door open. then move it to the kitchen counter and let it cool some more for 30 minutes. *now to prevent any smells first make a pouch out of parchment paper, place the board in the pouch, and staple the open ends closed. then make a pouch out of aluminum foil, place the board in the parchment paper into the aluminum pouch, and fold the open ends of the aluminum several times to make it air tight. do not open the pouches in the house after the board has baked and cooled.* I went to my garage to get the board out of the pouches. there were exactly no fumes or smells while I did any of this because of the aluminum pouch being sealed by the folds and opening the pouches in my garage. once installed, the board has been working ever since.
Wow, I just saved $$$$ on a new TV by using the baking technique on my LG TV. I was about to go buy a new TV but I thought why not try, I have nothing to lose. It worked, how crazy is that. Thank you for posting
I have an LG 42LE 5900 and mainboard failed... no pictures. Took out the green motherboard and put in oven for 10 mins at 195-200C. Left to cool and reinstalled. Worked!!!! amazing. New motherboard £200, reconditioned is about £40 if you can get one. This oven heating method does work.
FIXED!!! Had the same problem with our LG 47LV5500. Power would switch on but no audio or picture. Baked it for 10 minutes at 200°C, cooled and assembled it back, and VOILA! It was back on.
Thank you so much for the video!!
I have just repaired my mainboard in this way and the television has been on for half an hour now and it works perfectly a simple but perfect solution
Thank you for your feedback!
@@charlytorres5132 can i bake my y sustain board too? Will it work?
Yesterday our LG went after 8 years of excellent service right in the middle of a world cup soccer game, today having breakfast decided to do some digging on you-tube for some help before going to get a new one. And all I have to say is Thanks I Works, unbelievable but it really works, Thanks again
Awesome! :)
This process does usually work 9 out of 10 times but isn't a permanent fix. They will last anywhere from 1 week to a month if you're lucky. One thing I've found out is that if you do the heating process right and have the mother board placed right that it makes a huge difference in the life of it. If you place the mother board on a baking sheet flat with the 3 or 4 rubber studs facing upwards, this allows the solder to melt back down onto the pins rather than melt away from it. I bake mine at 400 F for 30 minutes with the oven preheated and then I turn it off and open the oven door slightly and let the board cool off slowly for about 45 minutes to an hour. My LG has worked now for over 1 year doing it like this.
Thank you for the feedback! I got lucky, my TV still going strong after almost exactly 1 year!
I did it the other guys way about 2 months ago but it just broke again, so this time I baked it 10 minutes on each side. Will see how long it lasts this time…..
I repaired my broken Vizio TV by doing the same thing this guy did. Thumbs up good work.
We almost went the route of baking the module, but I came across a post that said to turn off the TV and the set-top box, remove the power source for at least 15 minutes for both, discharge the power button by pressing it and leaving it alone. After 15 min approximately, I replugged both the set-top box and the TV into the electricity socket. Turned on both STB & TV. I believe ATT U-verse had to cycle through... then voilà, the sound was back! This happened a second time and I went through the same process, and again it worked! So glad I didn't bake the module.
Thanks for feedback for all here to review that solved your Sound issue. I tried similar process for my Video issue but it did not resolve. All should try Joni K easy method 1st. If no luck, perhaps Baking time for you as well! :)
We just tried this since our TV stopped working today, and it really works folks! Unbelievable !!! Thank you so much for saving us 1500$+ !!!
Awesome! :)
My in laws lg tv hdmi ports stopped working. I saw your video and now it works. Thanks alot. You saved us alot of money:)
How long did the fix work?
@@9toro428 it still works :). No issues.
While im waiting on a mainboard for a 55inch led LG board to cool ill write this....I have a repair shop and trust me this works on many components in tvs. I give the customer the option if the new or used part is to pricey. 15 bucks to figure out the problem and 10 bucks to bake and test for 3 hours if it works add 15 bucks for everything else and it comes with a 30 day waranty if it works. 40 bucks for a fix and waranty So far 4 years of doing this and i havent had one come back. Knock on wood! Its a 50/50 shot it works and my recipe is 11mins at 385 turn up to 400 for 6mins cool for 5mins then the Cooling fan for 10 mins with install gently while its partially warm. Bingo! Oh always a good idea to wait atleast 3 mins when you plug in power cord to energize the compactors. Well the main board works on the 55 led Lg now ill run it all night for testing.now time to go install a buffer board on a 50inch lg in my other shop and see if it worked. Good luck all
Thomas L, let us know your outcome and thanks for the feedback!
To prevent it happening again, never ake out the power cord while not in
use, let it be in standby mode always! I found out that the board stops
working when it has been left in a cold (below 10' Celsius) room for a
week or so without the power cord attached. So, never unplug the power
cord (tv, blu-ray surround etc). I`m baking my
board for 2 time now. Lesson learnd.
EDIT: Last time it lasted for 3 years, and it also worked today!
Update for all. After 6 months now, TV video and Ethernet, and all connections on Motherboard / Mainboard still working perfectly!! Thank you again Avrim Fishkind!! :) (Did I just jinx myself, Hmmm... :0 )
So I tried this with a lg55lf6100 and nothing changed. Still get no signal when. Hooking up my PS4. I do however have an electric oven and now I'm wondering if it didn't get hot enough when it was baking. Any advice would help
I'm about to do it for the 3rd or 4th time tomorrow morning.
Hi, Thanks for this wonderful video. I had a same problem recently with my LG smart TV (Model: LV3730-TD, 2011) and I followed the steps which you was mentioned. Now my TV working perfectly and many many thanks to you. This video was very helpful and I am very happy that without any additional cost I repaired my TV.
Thanks again.
Thank you as well for the kind words and feedback and so glad to hear it worked for you!
I did it and it works (1 full day of testing ,model 42LD630) ! Thanks a lot !
I tried this method last night, it absolutely works. Thank you to both the original post and you as well.
Worked like a charm. Picked one up free from offer up. I didn't want to use toaster oven. Maybe mistake. It does stink up house. Luckily did it around 11 pm and wife was asleep. I took it out side and pushed down on Heatsink with end of screwdriver. Been maybe 2 weeks now.
Worked for me with our older LG 47LE5400. Thank you !
Just did this and it worked like a charm! lets goooooo!
So, second attempt was successful but not 100%. I've lost functionality of all but 1 HDMI port, there are 4 on this model.. I believe that reflowing the solder multiple times also makes it brittle. I'm happy to have gotten another year's worth of service from this TV. This last HDMI port is starting to show signs of failing. Audible static and partial snow on the video signal are sometimes evident. Turning the TV off for several minutes allows the board to cool down and then the signals return to normal. I will buy a new TV when I lose this last HDMI port. If you are trying this fix for the first time, go for it! I got a year and a half of service from my first attempt. Good fix.
Thanks for the additional update! Someone else posted here they have had success 5 time now. :0 Perhaps a 3rd time (after your last HDMI port quits) might get it going again! But what a headache to do this over and over...
Charly Torres , I should add that it appears I had lost HDMI port #1 permanently prior to this second reflow. It didn’t work after this attempt. Also, I may look into buying a new board altogether for this TV.
Hi Charly, have a TV with red light on but the display does not turn on. Tried this bake at 200°C for 10 mins after worrying it might melt the plastic components but everything was okay and nothing had melted after the bake.
Unfortunately, plugged and screwed all back and didn't work for me. Thanks for posting the detailed video, was definitely worth a try!
Hi there, oh boy, so sorry this did not work for you. 200C might be a little low though... Perhaps google the make/model of your mainboard to see about melting point of solder they used if still interested in trying again. Can you tell us what Make / Model TV you tried this on? Thank you for sharing your experience!
Needs to be around 400 degrees. I use solder flux under chips, wrap up all but chips (without heat sinks) with tinfoil and foil tape, heat the mobo propped up 1/4 inch on a griddle, heat gun the chips till the flux rapidly boils out from under the chips, and slowly cool down 50 degrees at a time over 25-30 minutes. Then let the mobo sit for an hour. Don't ever budge a hot mobo. Put a thin layer of artic silver thermal paste on the chips before puting back heat sinks. The flux and slow cool down are essential for a good solder bond. A good solder reflow like this will increase chances of a fixing it to last and flux is cheap. This is how I fixed many Xbox 360's to last.
Philthy Blend, Thanks for the detailed feedback!
Fixed my LG47LW5600 the other day with the flux, griddle, and heat gun method. Working great now 👍 My wife was super stoked 😀
This worked for my LG 47LV5500. The symptoms the TV was having was it would work for a few minutes then turn off and on and on and off. I decided to unplug the TV for 30 mins then plug back in... now the TV would not properly work at all, black screen with only the power white light. After a few google and TH-cam searches I found the baking oven main board method which worked! @ 380 degrees for 10 minutes. Couldn't be any happy.
Awesome! :)
This genuinely worked. Im amazed. LG sucks. Your method rocks. Thank you!
I try this last night and it works Thanks had to bake it 2 times
Hugo, so glad this worked for you! Thanks for sharing!
Why 2 times? Mind to share?
Followed to the tee. Did not work. Perhaps my issue is different.
When I power on the TV I see the LG logo big and bright for about 1 second then the TV goes basically black. I can still see that there is a menu/window but it is barely visible.
I have an LG 47LW5500 and tried this trick out and it actually worked. I had a completely black screen with just a blinking red light before and everything is working now.
Awesome! :)
My LG oled TV randomly switches off. Most likely the board. Would this method fix issue?
Would it help to remove the heatsink and put flux on the IC pins before baking?
I be damned this worked.... Have a LG 55LW5600 ... No video no sound, just little power light on.... I was about to dump it when I found these videos talking about baking the main board, I said wth lets try its wasted anyways. I removed the main board and stuck in a toaster outside at 385F for 11min, it does stink so you want to try to do outside.... But WTH I plugged it back in the TV and its working just fine! I'm blown away about this trick...
Hey Marco, thanks for the feedback! FYI, After 9 months now, my TV is still working perfectly.
@@charlytorres5132 thats insane... Do you believe this process can be repeated? Amazing... Imagine how many people just dump the TV or get charged hundreds for repair...
Hey Marco, yes process can be repeated. Avrim Fishkind mentions he has had to do several times I believe. I've been lucky and mine is still working after almost 1 year (10 months)!
This totally worked. Did it yesterday. Any updates on how long this fix will last for? Thanks for this crazy solution, by the way.
Was watching my LG 42LD490 TV one evening and suddenly the screen goes blank. The standby light is flashing red, and when I hit the power button it goes solid red. Repeat and it's back to flashing red again, no picture. My first thought was the power board and, as I had a supplier a 10 minute drive away, I purchased a new one and fitted it...no change! I was about to give up when I found this video and thought what the hell. 15 minutes at 200 degrees Celsius later I refitted the mainboard, plugged in the TV...and it was magically working again. Witchcraft!
Plolov, so glad this worked for you and thanks for sharing your experience!
@@charlytorres5132 Thanks for the video and extending the life of my TV.
4:02 delicious. I like mine with a lil maple syrup and a silicone shake.
I don't know guys .... This seems pretty half-baked.
Did NOT work for me. I have the exact same 55LE5400 that is seen in this video as well. I did it at 385F for 10, all the other videos use that time and temp. I have a digital soldering iron, and at 200F, solder won't melt. I guess that I can try it again....
George P, thanks for the feedback. If you try again, let us know outcome. My son had an XBox years ago and process for it worked for a few months and then dead again. You win some and lose some but overall for many, process works so worth the effort before dropping more $ perhaps.
Worked perfect for me, Thank you very much for taking your time to make this video!!!!
I just did it to my 42le5400! It works. Had it stored away and just didn’t want to trash it.
just did a 60 inch LG motherboard on a tv that would not turn on worked perfectly i baked it at 250 degrees for 18 mins it did not smell one bit i picked the tv up behind a tv shop couldnt see it going to the dump LOL
Wow, funny - cool story! My TV STILL working perfect after this fix after almost 1 year! If it ever has issues again though, I may check out backs of my local TV Shops for a free one! Thanks for sharing.
Will this likely fix a TV with NO standby light?
it sure could what would you be out its been 2 months and this 60 inch tv is still working great!!!!@@robertmccoy9186
Totally worked for me! So pumped.
I read that you shouldn't do this using a gas oven. Is this correct?
I tried the 385 at 10 mins with about 20 to 25 cooling in the oven with the door cracked, then cooled outside of the oven for 15 minutes, I put the board back in and the tv did like before, where the red status light, turns to white and blinks slowly like three times. Then turns red after the power supply makes a clicking noise
For some reason it did not work for me I think this board is screwed
Thank you so much just did this and IT WORKS !!!!!!! YESSS
Thanks dude, YOU SAVED MY LIFE!
So it's usually the audio board that makes the tv shut off ? If i take off the back cover and put a fan it stays on longer
I have a TCL.ROKU 720P I had it 3 years like Half Screen is darker as the top brighter has a blue horizontal line
Across the screen
I dont throw my controller or remote at the screen like everyone else does
can you just use a heat gun or hairdryer to melt the solder and not unhook everything
yahooooooooooooooooooo tv's back up n running saved me money great thanks
Anyone had an issue with their older model LG not recognizing the inputs? Thanks for any advice.
What temperature does the oven need to get? Or is the toaster oven automatic for 10 minutes?
I have Lg 55, plasma. I have good picture but sound stopped working. Does this fix a " no sound" problem?
Does this work for other brands as well? I only see LG tv bakings on TH-cam.
It worked for our vizio twice, doing it for a 3rd time right now. Thr problem is everyone's input with varying temps and times, as I forgot what we had originally done and the video for vizio is now gone. I'm trying it at 365°/12 mins right now.
Has worked for me many times.
This method sadly didn’t work for me. I will have to get a new mainboard or a new tv.
I tried this on our LG tv motherboard and it worked. Did slightly under 200C for 10 minutes.
Awesome! :)
Did u put only to hit up just from above or with fan as weell ?
@@iliecosmin4827, was done in a fan forced oven.
It worked !!! LG - 55LW6500
I tried it step by step plugged it all in afterwards and put the cover on. Then finally turned it on and the red light flashes and doesn’t stop flashing and won’t turn on. I tried turning on with the remote and the tv itself and still won’t work, please help I think I may have fried the motherboard!!
मेरे पास २२इन्च एलसीडी टीवी है। जिसमें लाईट नहीं आ रही है। इसका पावर बोर्ड तो सही हैं इसमे डीसी ३४४वोल्ट तथा लोवोल्टेज ५.२ ,१५,तथा २० वोल्टेज आरही हैं फिर भी टीवी में कोई लाइट नहीं आरही हैं इसकी जानकारी दे।
I did this and nothing happened. About to try it for 395(10° hotter) and for 15 min instead of 10
What was your outcome? Considering doing this with mine.
Worked for me lg 47lw5600! Thanks.
I have a LG TV that I have done this 5 times with. I found this method the first time it stopped working. It has stopped working 4 more times since and every time 10 min at 385 has brought it back.
5th times a charm - Thanks for sharing!
Hi, this process worked for me. Someone knows how long the procedure last or knows if it needs to did the process again?
What temperature and how long do i bake the motherboard?
Ummm my mind is blown, this just worked for me
You are kidding... we just tried this and it worked... we were told we needed a new main board... then found this video...
Has anyone done this to ther LG 55G2? Turns on just fine but then picture goes out. Sound stays on ok. Turn it off and back on same thing (lg screen is on then when it goes to the source, video goes out but can hear the sound)
It worked for me. Thanks
Where is thw power button on this tv
Why putting in the OVEN?
Putting it in the oven will heat up the solder connections and melt them together again. Basically reconnecting any faulty lines
Do anyone know where I can find a replacement motherboard?
seems they use cheap tin-solder in China, everything cost-efficient. And after some time these soldered joints brittle. Of course, mysteriously this always happens when the term of guarantee has expired.
Is it still going?
this worked for me too, on a vizio P502ui-b1e.
Thanks Agent Smith.
Can I use gas oven any idea please guys
Glad it worked!
Thank you again for posting this TV Motherboard baking method!! Your video saved the day for me and Many others!! :)
I totally ruined motherboard by this method. Every single cap popped and some parts even fell off lol it was totally burnt. Maybe if surface is perfect and you have high heat for like 60 sec or smt,but not 10 minutes. I can post pic what my mb looks like,totally totalled lmao
Hi Smoletss, I am very sorry to hear that! I suspect it may have been s misunderstanding on temperature or faulty oven or placed to close to heat source in oven... Sorry again. Yes, if you don't mind, please share pics of motherboard, oven used and where placed, and advise on temp you used. Thank you for your feedback.
Can i use a microwave?
my probelm started with a power surge so will cooking with the turkey work LOL
A Dad definitely wrote this
did I poison my food doing this?
Hmmm... My guess is as long as you didn't cook food at same time you are probably OK. :)
If you put some potatoes and a joint in with it. Probably..
anything that replaces the oven
BONUS: The Ethernet connection to TV stopped working prior to video issues and now working again. (I thought it was my router in past and didn't pay much attention as I primarily use laptop connected to TV via HDMI.)
My tv LG 42LE8500, made in 09/2010 stopped work. The led of power on/of, source,volume up/down, channel next/previous were working but no picture, no logo, no sound. Just a blank screen. I searched in internet and i saw videos and tutorials like this. I thought all these information was wrong and I will destroy my tv if I try it. They all say the same think: bake the motherboard of your tv for 200 degrees of celsius for 10 minutes. I call to a tv technician΄. He explained me that repairing cost will be almost 100 euros. I say ok. But it was far away from my home. I have not to much time to travel so long for a tv. So i decided to try this ΄΄crazy΄΄ method. I remove th back cover of my tv, then i removed then connections carefully from motherboard' they have different ways of connections. I preheated my electric oven at 200 degees of Celsius for 15 minutes. I put the motherboard on a cardbox in my oven. I baked it for 11 minutes at 200 degrees. Then i put out from the oven the card box and i left it to cool for 20 minutes. I have to say there is a smell like burned electronics. All the windows WERE open and this smell soon gone away.
Then I put the motherboard back in my tv. And then i connect the electricity. I press the powen on and ... voila!!! The logo of Lg ant then the appearance of screen saver. My tv was workIng again. Many thanks to all people of Republic of Internet
Gracias a mi me funciono de maravilla en un modelo 47LW5700
LG4700 - This will be the 2nd attempt in about 1 year . 1st attempt was successful, no picture or sound- TV power light only.
Thank you for your feedback! Hope attempt 2 works!
I will try it today..
That's crazy good 👍
OK , Im about to do this shit ...only one concern ..doesnt plastic melt ???
Did this work for you Srdjan B?
Charly Torres suprisingly . Yes it did! :-) ..but unfortunally two months later same problem again..i "baked" it again. let's see how much will it last now.
Just a theory but I think a slow cool down helps to last longer...
You're probably right..well ..I got pretty bummed out when it died second time , both times I think I had let it cool down (drank couple of beers in meantime :-) ...so I don't know at this point how much will it hold ..all I know I really like this TV , it got really good picture , nice design , solid 3D ...biggest problem is that I bought this tv used , and I don't know if it was already baked couple of times before I did it...also I was talking to a repairman who told me that when it dies first time it is important to do "reballing" properly ...even then he could not give a guarantee larger than 6 months - 1 year ... other option is to order mainboard from China but i have searched all the internet and found nothing ...so fingers crossed :-) You know ...even if it fails it was cool to do this thing , and see it work ...even funnier to see the expression on people faces when i told them how I repaired TV ..They were like ..Whhhoaa :D ... but i wouldt even consider it without your vid ...so thanks again buddy .. I watched world cup in soccer , Novak Djokovic winning Wimbledon again ...good times :) ...it can die now ..oven is ready ;DDD
+Srdjan Bogunovic I watched it too. Croatia was really good, they got robbed from the first place because fifa corruption. Are you croatian?
Thanks
Muito bom.... esclarecedor, obrigado.
De Nada! (You are welcome!)
Does this work for static screen?
Hi, by "static screen" I'm not clear if you mean static on your screen or a frozen / stationary image on your screen. Regardless, I think this method could help you. When the CPU solder ball connections get loose on the motherboard, they can cause all kinds off issues from video connection issues to numerous image issues. As you can see from other posts here, this method works to resolve more often than not. If you try, we would enjoy hearing back if worked for you or not.
@@charlytorres5132 I have the static screen problem as well. Apparently very common for LG TVs with bad mainboards.
I fixed mine right now and work like a mf😂👌
dond do it
