I’ve applied this fix 4 times so far, about once a year, and it has worked every time. Thanks for the weird fix! Guy
Woke up one morning and turned on my LG 55LX9500 to find a black screen with a high pitch noise coming from the speakers. Baked the Main board at 385F for 10 minutes and that fixed my 3D television! Another success story. Thanks to you and Zedic!
Just want to thank you for this video! I followed your instructions and fixed my tv. You're awesome! LG wanted to charge me $350 to fix it when all it needed was a good baking. So glad there are people like you willing to share your knowledge and experience. Kudos to you!!!
Thank you!!! I just finished fixing my 47"LG. I had put up with the HDMI ports being "broken" for over a year. I had an HDMI to composite adapator and it was ok until the unit would not boot. I pulled the board out in about 20 minutes, cooked it as per your instructions. Let it cool during dinner and then buttoned it up, and tested it. The whole family was amazed!!!
Thank you for this post. I have a 7 year old 42" LG tv and none of the HDMI ports would work. Baked the board at 400 degrees F for 10 minutes...let it cool in the oven for an hour and a half ...put the board back in and bam!! Worked perfectly.
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.
My LG 55LE5400 was having HDMI issues connecting to anything other than the cable box. Xbox and Apple TV would not work. Saw this video, read a bunch of comments, and went for it. This actually worked!! After wait for the board to cool off, I did the test with my other devices and they all connected. Thank you for the video and the many people that tried this before me.
Today I have tried this method with my old Philips 32 inch TV that I bought in 2013. A week ago it struggled to receive any orders from the remote or the back panel buttons, but the LED was on the whole time. I baked the board twice because the first time didn't work, but the second worked flawlessly. Thank you!
Just found this wed posting and had the same problem with my 55" LG-LED TV. Took it apart and followed the instructions as stated and I am happily watching my TV again. Took me about two hours to complete the repair and hopefully this will save me buying another TV in the future. Thanks for sharing this idea with all of us! Paul
Paul Schmidt is it still working?
Just tried this on an LG 55LW5700 55 Inch: Preheated the oven to 385, baked for 10 minutes exactly, allowed to cool for 30 minutes. I went the cardboard method with a sheet of aluminum foil on top. 100% worked, TV powered on and gave me the "Life is Good" slogan and I agreed. Thanks for this video and for all the comments on various methods!
This fixed my vertical line problem, thank you so much! The repair shop quoted me $300 to fix it and recommended I just go buy a new TV! LG 42LV5400, 5 yrs. old.
Have an old LG 42LE8500 with Display not starting up anymore. It baked the motherboard with your method and it works. Absolutely made my day! Thank you for the video!
I'm amazed. This worked for me too, on an LG 42LE5400 built in February of 2010. The set suddenly went dark and quiet. Afterward it would power on, but without any picture or sound. Baked the main board at 385F for 10 minutes on a piece of cardboard. Thanks for posting the video, and the link to the original article, which was also informative and helped me get over some jitters as I gave this a try. You saved me a few hundred dollars, especially if the TV stays fixed. And if it doesn't? Back into the oven it goes!
I have the same tv did it work for you
Baked a board from an older 42" LG. Went with 300 degrees for 15 minutes. It worked!
And the smell wasn't that bad. Many thanks!
Someone has done a lot of trail and error and can up with how to re-solder all components in 10 mins. I really appreciate you taking the time to come up with a solution that only cost a can of Febreze. I will make sure to run this test each and every time I have a main board problem. All systems GOOOOOOOOOOOOOOOOO!
i came across this amazing idea and did the same thing for my LG 42 LED mother board and it worked. LG customer service was asking for $350 to have it repaired. i save myself some money courtesy of this video.
This fixed my TV! I was skeptical at first but I just swallowed my fear and popped it in the oven. 40 minutes later my 55lw5600 was working perfectly. I can't stress enough how thankful I am. Saved me a huge amount of money.
My LG 42LV5400 that is 5 yrs old suddenly went dead last night. Pressing the power button only showed red light briefly then went dead with no pictures at all. I've been looking at videos where you need to replace bad capacitors. Then I found your baking method. Two hours ago I opened up the back of the tv and inspected everything. The power supply board had no bad caps so I went ahead and baked the motherboard. Now my tv is back working again. I baked computer motherboard before to fix issues and didn't know this method also worked for tv mobo. Thank you very much!
This 59 yr old non-techy woman just followed these directions and sure enough my TV is now fixed. Thank you.
390,000 views … would never have thought so many people would see this and find it helpful. So much $$$$ saved :)
Is the TV still working? If you dont have it by now, how long did it work after heating it?
Thanks to you man!
I saw another video where the guy was trying to fix the HDMI issue with a heat gun. I tried that, but when I connected everything, the LG --:-- issue wasn't fixed, and also, have the screen was messed up. So I figured the TV was headed for the trash. But I went ahead and tried the oven thing, and it works, and the screen looks GREAT. And the HDMI issue (which had started way before the LG --:--" problem was also resolved. Thanks to everyone who made videos. Amazing way to save a few hundred bucks.
Absolutely works. My TV died Xmas day. I just did this now. I ordered a new power board thinking it was that. I did 200degree c. Preheat. 10 mins. Cool down, refitted. And straight away it was on. Thank you so much!
My LG 42LW5700 can't even start, black screen, red light ticking. I put it in the oven 200°C for 10 minutes, and IT'S WORKING!!!!! Thank you so much! You saved me 400 bucks from my LG local official support, almost a new TV! Best regards from Chile.
Well I ran across your video after I lost the audio in my LG 47LE 5400-UC. I chose to try the baking method before I mailed out the board and spent $75.00. I am very pleased to say it worked and I am much appreciative of your help. I had to modify your method a little because I have an electric over. I banked it 10 minutes at 350 and let it cool outside of the over for 30 minutes. Installed it and everything works great. thanks so much sir.
Glad to hear it.
When u said electric oven? Did u mean "microwave" oven ?
One more! It DOES work! I was about to imagine my life without a TV for awhile, but I went for it and there it was! Alive again! Thanks man and greetings from polluted Mexico City!
Thank you THANK YOU!!! It's the third time I solved the failure on the LG TV 55LE8500. Every four years, baking, and ready to go. Last time, today following your instructions. I have the TV set since 2010. Greetings!!!
Our LG 42 didn’t have a picture or sound. Baked it and to my amazement it actually worked. We were looking at buying a new motherboard now we don’t have to. Awesome, thank you sir.
Thank you so much I'm not going to lie I did doubt you for a second but now that I see I've done it for myself for my 60 inch LG I got it in 2011 it's a 60p z550 plasma TV put in the oven 10 minutes and it worked!!! usually I don't comment on these RUclips videos but on this one I have to because it really worked thanks I really appreciate it you saved me alot of money saved me a good 400 dollars.!! means a lot to me God bless!!
same here! ...saved me $400 ...Thanks Uploader!
I can't believe it!!! I'm stunned! It worked! We have a Plasma LG 50PK950 and the inputs suddenly stopped working. Figuring we had nothing to lose. We baked it at 385 degrees for 10 min, and let it cool in the oven with the door open. We did open doors and had fans exhausting the bad air out! I called a TV repair guy and it would have cost approximately $150 to repair! Thank you so much for the much needed (inexpensive) repair!
It's been 4 months and it just did the same thing! The board is back in the oven, fingers crossed it works again. One note when we did it last time the power button/remote wouldn't work but for some reason when I powered on our Fire TV it would power on the TV! We just made it work!
Well, it worked again!!!!!! And now the remote works now too! Let's see how long it last this time! We'll keep doing it as long as it works!
I got this tv from a buddy at work he was going to throw it away and I tried this!All I have to say is that this freaking worked and your a lifesaver 🙌🏻Thank you!
I initially thought this was a joke and was hesitant to try it. After I found other examples of people doing this with computer motherboards and video cards I decided to give it a try. I had nothing to lose. I followed the directions exactly as in the video and now my TV (LG 47LE5400) works great.
Two things that are amazing. (1) Your method worked like a charm for me. 10 min at 390 F. Aluminum foil instead of cardboard. Thanks.
(2) HDMI in LG TVs dies precisely at 5 years after the TV was manufactured!!!
Unbelievable. My 55LW5600 was manufactured in Nov. 2011 and the HDMI stopped working two days ago. The board was loosely attached to the frame. Maybe LG knew this long ago and did not want to put too much mechanical stress on the board?
I was sceptical and had nothing to lose.
I did this on an LG 42LE5900 ,11 mins at 200 degrees C and then let it cool in the oven for 1 hr. Put the board back in and TV works. Amazing. Many Thanks...
Thank you! My LG Plasma TV started having issues and everywhere I looked on the internet pointed to a faulty Zsus or Ysus. I came across your video and thought why not? Baking my main board completely fixed my TV.
Worked for me too. HDMI ports are also OK now (haven't been working for a year).
Disassemble the motherboard (take down all plastic attachements). Pre-heat the oven to 200 degrees C , put it in on a cardboard for 10 min. Leave it for 10-15 min in the oven to cool down slowly. Another 20-30 min outside and reassemble.
Good luck!
Crazy, right?! Well I had nothing to lose. I've taken my 60pz550 to a repair shop and they said they wouldn't fix, it would be cheaper to buy a new one instead. I shopped online for a new motherboard and nothing. So I baked mine, said a prayer and viola! I'm watching tv again! Thank you sooo much for your video! Not one penny spent. Now I'm praying it lasts for a few more years.
so its been one year, does it still work?
A friend had put his LG 47LE5400 out to the curb for trash pick up right before I stopped by. Having an electronics background, I figured I'd try fixing it. When I opened it up, it looked a little more complicated than I expected. I was talking to a co-worker today who said he worked in a TV repair shop prior to this job. He told me to go on youtube and check out baking the board. I found this video and tried it. 375 degrees for 10 minutes. Let it cool in the oven for 20 or 30 minutes, reinstalled it and now I have a working 47" LCD HD TV. Life is good
Thank you Avrim Fishkind
Good story .. glad for your success.
Bought a 55" 120Htz 55LE5400 from someone on Craigslist for $40 that was freezing on the LG logo like this, thanks to you I had it up and running again in less than an hour. I was simply floored that this worked, thanks SO much guys. As a side not, the smell really wasn't a big deal. Just smelled like well used computers did in the 90s for a bit.
This works. We were very skeptical but tried it and everything works just fine again. Thank you so much for posting this remedy, and for all of the comments validating its success. cheers!
This works. I followed the (updated) direction to the T. 400F for 10 mins.
My 9 yr old 47-LW5600 tv revived. I had never opened a TV before and it was super easy. Thank you !
You’re welcome.
I can't thank you enough. someone gave me this tv because of that error. i am not usually brave enough to attempt removing or repairing a board but watching your video made me confident. Now I have a nice working tv in place of the annalog one i have been using!
I have the same exact TV, bought it at the end of 2010, died about two months ago, or at least the video input from the HDMI ports did. Otherwise, everything worked. Just baked the board in the oven, and now I get a signal on my HDMI port.
Thanks, for the excellent video!
David Duprey uu
Duuuuuuudddeee! fixed LG42LV5500 baking motherboard in oven as instructed! awesome! Got tv from someone's trash and cost me nothing to fix! you're the man brotherin! thanks!
Worked for us! LG 47LW550T back iin business with all HDMIs. Thought we'd have to buy a new TV so this really saved a few quid. Used 190 degrees C for 12 minutes in the oven with some foil over the top and then let it cool for an hour before refitting it. Lets see how long it lasts.
Ta lad, was looking for centigrade figure...will this stop flashing TV screen problem?
SoI thought this is so odd that I'll just have to try it! I have a Cello TV that has power, no picture or sound that just stopped working about 2 weeks ago. So I opened it up, took out the mother board and put it in the oven for 10 minutes at 200 degrees C. I let it cool down for about 30 minutes and put the TV back together. It was like having a factory rest. It's now working perfectly. Thank you very much Avrim, your tutorial saved me buying a new TV!!
Hello Avrim, It's absolument incredible, I putted the electronic card beethoven the oven (my wife thought that I was crazy...!!!), later I made the tested and "voilà" the TV began to work again.
Congratulations and thanks a lot.
Avrim, many thanks for sharing your fix. I had the same problem with a 5 year-old LG Model 42LE5400. I followed your instructions and it worked. I used a small electric oven. I did it in my garage to avoid any smell and fumes. I pre-heated the oven to 375/380, then placed the board inside on a piece of cardboard in the middle of the oven, closed the door, turned the temperature up to 395/400 and left it for 15 minutes, then switched off, opened the door and blew air with a fan over the oven to cool it all down and blow the fumes out of my garage door opening.... after 10 minutes, it had cooled down completely. I replaced the motherboard and the TV was working again. Thanks!
Ok, you guys rock. I had my doubts, but not much to lose when my LG 47LV5400-UB just stopped putting out any signal. The power was on but nothing happening. I found this video and gave it a shot. Worked like a champ. TV is back up and running perfectly. Thanks!!
My LG had constant black screen after showing what HDMI it was on, so I tried this oven fix, nothing to lose right?
Well it worked & I was able to get back to enjoying a good game session.
Thank you for sharing this fix. 😊👍
Worked like a charm for me... 10 -12 minutes in a 280 degree oven, some connectors are loose upon removal so go easy. After 15 / 20 minutes reinstalled board and it worked. Thanks Avrim...:-)
I had the same HDMI randomly stopped responding (started yesterday) -- just finished by 385 10 minute bake and this is absolutely no joke, it really works!
Call me a believer now that I tried the described process with success! I have a LG 55LE8500 and bought the tv in 2010. The tv was working fine, yet I was not able to connect my Directv receiver using the HDMI ports. I initially thought it was a Directv receiver problem until I plugged my Roku player in all of the HDMI ports. In all, the process took about an hour to unbolt the back panel and bake the mainboard (10 minutes to bake and 20 plus minutes to cool..) I was very skeptical that it would work but thought what the heck as many vendors do not sell the mainboard for my tv any longer. Thanks for the post as I would not have dreamed of trying this process.
I just fixed an LGLN5400 doing this. Picked it from someone who was going to throw it away. Works like a charm! Life is good!
And yes, it stank up my kitchen, but who cares? :)
Nice video, it worked for my LG 47LW5600. local tech got me $40 for checking what was wrong with it, and said it was the mainboard/useless. i was not patient to wait for the part to be ordered and wait... got it home and tried the beaking, worked. you saved me buying new, thanks!!!
Worked great! I have an LG 60pz550-ua. The sound stopped working and then all the HDMI ports stopped working. Put the board in the oven for 10mins and it’s working perfectly again.
It worked for my LG 42LV5400 ... Used the kitchen oven at 385F for 10 minutes....works like a charm now...
Thanks for sharing this video !! Saved me $$$!!..
Hi, I "had" the same problem, note that I wrote "had" I removed the mother board wrapped it in tinfoil, put it in my oven for 10 minutes at 196 degrees centigrade, no smell really to speak of, fitted it back in the tv, plugged it in to the mains and the result is my TVs is as good as it was before it stopped working. So if you have this problem, have a go it cost me nothing but a few minutes of concern about nothing and ended up with a great result! Thank you, and thank all the others who took the plunge and motivated me to have a go!!
This actually WORKED!!!!!!!!!!!! Holy crap! Took the motherboard out... cooked it and bam!!!!! Thank you sooooo much! Almost bought a new TV! Followed what you said in the video... Id buy you a beer or 2! Thanks man! My screen was all black... would turn on, cooked the board and it was fixed!
Just fixed my LG 3D LED TV 55LW5700 using hot air gun 370°C only on IC101 for 2 minutes (remove the heatsink) and it WORKS, thank you for the video.
The problem was no video, no backlight, red indicator was flashing (slow).
Before that I checked the power supply, it was fine, PWR-ON 3.5 volt, 12&24 volt in P201, and 56 volt (63v when backlight is on) in C256&C257
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 $1400 TV for FREE !! Thanks for posting
Can't believe this actually works, just did it today on my 48" LG. Freaking miracle.
Thanks to your uploading I have just fixed my 7 year
LG42LE5500.Excellent work as I was totally disappointed with the fact that there was not mother board available in the market.
THANK YOU!!!
I want to confirm that works. I have an LG LE4200 theatre the HDMI ports all went out after 5 years. 10 minutes @375F an everything works. Thanks!
I am stunned. It absolutely worked. Thanks for posting this. I've seen nay-sayers elsewhere on the 'net who think we're mad for doing this but it's worth it because it works!! The only alternative was an out of warranty board replacement so I thought it was worth a punt! Glad I did it!
Just baked my LG 50PX950 main board (@400 for 11 min) and... *MAGIC*! my 2000$ 10 yo 3D Plasma LIVES AGAIN!!! Thank you thank you THANK YOU!
Thanks Avrim for this very helpful video! Today I fixed my LG TV by using this method. I used my toaster oven for this purpose because I could take that one to my backyard to avoid the strong smell emits from board when the soldering melts.
Issue: When I push TURN ON button, red light blinks two times and then it becomes white. Nothing else. Black screen and no sound.
Make: LG
Model: 47LW5600
Temperature: 400 Degree Fahrenheit
Time of baking: 15 minutes
My TV worked right away after I put back the motherboard.
Thank you, thank you, thank you! Worked beautifully. First day of the New Year, TV comes up stuck. Never had issues with this TV in twelve years of ownership. Followed your example and it now works beautifully.
God bless you in this new year and thanks again. My wallet thanks you too.
The smell wasn't as bad as I expected though. Thankfully.
Fantastic! I had an issue with the tuner on LG 42LE5500 made in 2010; Digital channels were appearing normal, but analog channels were complete blank; scanning could not find any analog channels; after this baking recepie, it is all working as it should! Alive again in 2018! Many thanks! 👌
we recently did this by putting our whole tv in our shed on a super hot day and it worked!!!! we will have a video coming out about it soon!!!!
very cool !d like to see that !
I have a glass conservatory that get past 140° F on a hot day. Will buy a cheap scrap TV on marketplace just to try. Thanks
Just fixed my LG TV, thank you so much for the advise. Must admit I was skeptic at first, but the video was very easy to follow. Thanks again for saving me $$$ on a new TV......CHEERS
My LG 50NL5400 died (No picture). I tried this trick as a last resort. 385F for 10 minutes. Pre-heated the oven and put a good oven thermometer to double check temp. In it went and COMPLETE FAIL. The chips came off, the connectors melted, the cardboard was catching on fire and it STUNK!!! Time to shop for a new TV !
Thanks many MANY time man.
With your video I saved my 47 inch TV LG5400 from ending in the electronic scrap place too early in it's life.
I was sceptic at the beginning but after reading all the comments I decided to give it a try this morning. It's working fine since.
Again many "MERCI" from Montreal, Canada.
I pretty much have the same LG TV from about 2009 and have used this trick about once per year for the past 5 years. Works like a charm everytime! I'm also getting pretty fast at taking it apart and putting it back together. Nbd.
What temperature and how long you baked
Thank you for sharing this. Worked for me on an LG 42LD690 that had a red glowing power on light fault. 10 mins at 385 F. Was worried that the small components and plastic connectors would melt but no problems and now works great.
I was the office today (Sept 27, 2018). My wife called me on the phone, said the TV (LG 47LW6500) went out. Oh boy, had it! It would power on, but show no video (not even menus), and play no audio. I bought it in 2011, so even my extended warrenty had expired. So, I took out the motherboard and baked it at 385F for 10 minutes. When the timer went off, I turned the oven off, and opened the door. I let it sit in the oven for 30 minutes. I then took it out of the oven and let it cool an extra 15 minutes. I put the TV back together.... and it worked perfectly!!
UPDATE: Just today (October 2nd, 2021) my TV went out again. I repeated the same steps as I mentioned above, and it's back to working great!
holy shit, unbelievable, it worked!! My LG LE5400 55" tv died 2 months ago (bought 2/2011); Just went blank while I was watching it. I narrowed it down to the mainboard as the problem. The lights powered up, but no sound or picture. I haven't had issues with the HDMI ports, but came across this and figured I would have nothing to lose. I baked the board for 10 minutes at appx 375-385f (wrapped in foil to reduce the smell as another commenter posted, but on cardboard). Let it cool for about 30 minutes, reinstalled, and turned it on. My tv works again! Don't know how long this fix will hold, but do it! Thanks for posting this Avrim!
This genuinely worked. Im amazed. LG sucks. Your method rocks. Thank you!
This absolutely works!!! just brought all the HDMI/USB/AV ports on my LG42LE5350 back to life. Will see how long this lasts, but for now, this 'trick' has certainly saved me a few hundred $$$
Worked!!! on my LG 60PN6500. TV would shut off randomly during use (sometimes 5 minutes, sometimes 1 hour) progressively got worse and worse. I installed a fan behind the TV which helped for awhile, then I had to open the window to cool the TV and it would work again (-10C in Toronto right now) Decided enough is enough. Baked it in the oven 385 for 8 minutes. Let it cool on the top of the oven. Reinstalled it 10 minutes later. And voila. Literally Magic. No more shutting off, even removed the desk fan from the back.
THANKS SO MUCH!!!!
Johnathan Brabant is it worked really? Mine also stopped working mother board. Should i bake it ?
Parimal Ghelani yeah it honestly worked for me. Still works today like brand new, don't even need the fan to cool it anymore. So grateful I found this video. Give it a shot it was 100% successful for me.
Johnathan Brabant
my microwave has convection mode, microwave mode and grill mode. Which is that i use??? Plz answer
I wouldn't put it in a microwave. I would use an oven (even a toaster oven), perhaps I misunderstood though. I would chose convection mode. Grill mode should also work, as long as the element on the top isn't lit. (you don't want it to be hotter than 385F. (400F is probably the highest)
Johnathan Brabant i did it on grill mode and it didn't worked. In my microwave model. It has microwawe
Convection (i think it microwaves and then switches on the fan, but. Ot the heating element overhead)
Grill ( visually see the heating element glowing red)
Anyways after that didn't work. I borrowed a heat gun and did that direct blowing around the mosfets and audio chip. But it didn't work either.
Card is fine still. I mean still in the same situation. Picture fine and no sound.
Should i try convection mode?
Worked like a charm! My 55LE5400 LG TV got stuck at the startup screen. Followed the instructions to the dot and it's back to normal again. Thanks for the post!!
A.Fishkind rules! Just completed the steps and it worked! Awesome job man, out there saving people cash.
I had a LG 42 42LE4500 and I also got in 2010, recently stopped working and followed your advice!!!! Thank you so much
Chalk another one up to the "it worked" column. I payed $100 for this nice LG 55 inch, it took 5 minutes to warm up before the lines would go away. I figured no big deal, but over time it got worse and eventually the lines never went away. I watched several vids and did it myself. 10 min @ 385 and it worked like a charm !
Worked for me!! HDMI ports went out a year ago and the rotating cube happened last night. Baked for 10 minutes at 385 degrees. Then let sit for 20 -30 minutes until cool to the touch and Boom! shit worked. HDMI and all! Thanks Avrim!
P.S. turn on your vent!!! Had slight smell but nothing bad.
I did this when sound went out on my LG 47LB5DF UL TV (2007 Build) and was pleasantly surprised when the sound system came back on.
Cooked it in oven for 10 minutes at 385 degrees.
It really works on mine LG 42LE5500 TV. Tried it yesterday thinking that I going to dispose the faulty TV anyway, so no harm trying. Unbelievably, it works and bring back my 8 years old TV to life. I covered the main board with aluminium foil before placing it into the oven afraid that it will further damaged my oven. Set the temperature to 200 degreeC and 10mins. Left it cool and screw back. Surprise everything works as per normal. Thanks!
just did this on my 55LE5400 (exact same model as in this video but the 55" vs the 47" from the video) and it worked like a charm. i did use a toaster oven as i had seen in another video online so that i could do it outside rather than stinking up the whole house using my main oven...either way, thanks for this! we'll see how long it lasts!
one note: when i first reconnected the board, one of the ribbon cables was loose and only half the screen came on (the other half was garbled). if that happens to you, try re-seating the ribbon cables at the top and make sure they're both set correctly and solidly. once i did that, everything was 100% back to normal.
I just used the kitchen oven, I couldn't smell anything.
As an electronics technician I kinda had my doubts. I literally just finished this process on my 8 year old Vizio 47" since I had nothing to lose. Works like new now!! Awesome! I guess I'll hold on to those $500 or so to purchase something new. Thanks for the video explanation!
I couldn’t believe it but I tried this on my parents LG that took a dump and it works!!!! And it looks better too!!
Worked for me unbelievably. Was resigned to having to buy a new t.v, even checked cost of replacement motherboard but hard to find now and range from £50 to £200 so tried this method really not expecting much. LG 42" stuck on start up screen. Baked at 196 ish Celsius for 10 mins and bingo works as good as new. Brilliant, thanks.
David Hughes-Jones hey what object did you place the board on before putting it in the oven?
JMK Writes: I tried this with a toaster oven & only got half of the screen. My wife said maybe it cooled down to quickley, so 2 weeks later I tried it again and let it cool down with the door closed & I was plesantly surprised that it worked, I have a full screen. We'll see how long it lasts.
Unbelievable, baking the board worked! I have an LG 42LE5400 which lost it's picture and sound. I opened the TV up to get the main board part number with every intention of simply ordering a new one. I quickly learned the main board for this model is very hard to find. I, therefore, decided to try "baking" the board per this video's example. I put it back together and it works again. I do not know how long it will work, but I am simply amazed it worked at all. Wow.
Avrim, It worked for me on my LG 55LM6200 Mfg 2012. This was the last resort. I went through the power supply and checked/rechecked every other possibility, including testing the capacitors and diodes. I checked all of the wires and connectors, removing the boards many times. My set would come on sometimes but not others. It mostly wouldn't turn on but every once in a while I could get it to turn on. When it did, it worked perfectly. When it didn't, I'd get the dreaded blinking red light. I spent three solid days on it.
Yesterday, I decided to try this method. I got wax paper, put the main board on it and enclosed the board in a wax paper pouch. I folded all of the edges and stapled them. I then made another pouch out of aluminum foil minus the staples and sealed the wax paper pouch in the foil pouch. I saw this in a different video intended to minimize the smoke and odor. I put the pouch on a piece of cardboard in the center of my pre-heated 380F oven and baked it for 10 minutes. When I opened the door I got very little smoke and odor. I let it sit in the oven with the door open for about 5 minutes and then took it outside and let it cool for about 30 minutes. I opened the pouches and let it air out for quite a while.
I Installed the board yesterday afternoon. I have turned the TV on and off at least 30 times now and it has worked every single time! The TV would have been out for trash pickup tomorrow but now my daughter has a perfectly working 55" in her bedroom. Needless to say, we're both thrilled! Thanks for posting the video!

October 03 2018 and it work, i have a tv/monitor it's a samsung T27350D SyncMaster, i have to plug is in and unplug it several times before it will come on so after looking at this video i tried the procedure of baking the mainboard at 350 degrees for 10 minutes and now it's working perfect, so the people who are saying it can't work it did not work for you but it work for me. Last but not lees i must say thank you very much Mr Avrim Fishkind you are the best.
WOW !!! Fixed my LG 50PK750 TV 3 days ago with this method and it still runs like new. Also ordered a replacement board just in case but for now i am very curious for how long the original one will last after the 10 minutes baking trick. Thanks for sharing
where did u order the replacement board from?
Alain JM Fradet Found a used one on Ebay. Very rare item to find on the internet for this model.
Mine lasted 4 years. Crapped out again last night. Going to try it again. You never know might work.
This worked for me -> we'll see how long, but no issues at all so far!
Best thing I learned from the internet this year!
Just fixed my 42le5400-uc with this method. First time the backlights came to life but had a bad picture. Had to do it a second time at 395 for 15 minutes. Turned off the oven and opened the door to let it slowly cool to room temp without disturbing the components. It fired right up after that.
Glad you persevered and made a second pass...
I have the same exact TV model as the one in the video. My TV was bought in November 2011 and failed just a couple days ago May 2018. I already had a replacement television in a different room so I figured what do I have to lose I took my toaster oven outside and bake the board at 380 for 10 minutes I let it cool down for a half an hour and now the TV works just fine. Absolutely amazing thank you as I was researching how to fix it for a day or two figuring I would spend a couple hundred dollars or just put it in the trash.
$0 and TV works that's a win-win I recommend this video to everybody.
It is now September and my TV is still working fine. Thank you for the video. I just wanted to check back in and let people know it still works I might check back in another 3 to 6 months to update my post.
Great video! I have the same TV (47LE5400) purchased in Dec 2010 that quit working yesterday (component and antenna connections still work). Also saw the Zedic site that shows the same fix. I'm going to bake the main board tomorrow and see if it works. Thanks again for posting this!
+Twin Cities Dashcam IT WORKED! Awesome! Thanks again for the video!
+Avrim Fishkind - were you concerned about melting the parts on the motherboard? like the component input jacks, etc? i have the exact same situation and am wondering what to do.

I just did this today. I have an LG LV5500 smart tv bought 1/2012. The on/off light would flip on for a second and then nothing. Took 15 minutes to take out the motherboard, placed it on a piece of cardboard at 385 for about 12 minutes and then let it sit for 45 minutes. Put it back in and everything works like new. Good luck!
