- A tip from other commenters: Adjust the temp to 285F and bake for about 18 minutes. This seems like a safer temp to ensure the solder doesn't completely melt and drop other components off.
July 2018 Update: The TV is still working great! You'll see in the comments that this really does work. - Навчання та стиль
I have done this process two times in the past two years and it has helped keep my TV going for some time. Popped on this video to double check the temp and time settings while I leave it cooking. Hoping to get at least another 6 months or so out of this TV before finally getting a new one. I've had this LG for almost 9 years now and really like it. It looks pretty amazing- except when it is broken.
Hi everyone. It has been over a year and our TV is still working great.
How long would i need to bake it in the microwave?
Wow
Jeff Wick thanks for the update! I hate fix-it videos and the creator doesn’t update the status of the repair! I’m considering trying it once but I’m not sure I would have the patience like others will removing it off the wall and all the work involved! Thanks again!
Worked perfectly for me. I placed the main board on aluminum foil over cardboard, with another sheet of aluminum foil over top. Let the board cool and install. Worked right away. Thank you for sharing this video.
greetings, still working, did you do something different from the explanation?
OK, I'm glad I decided to watch through your video. It doesn't say anything different from any of the others, with the exception of the components falling off, but your son rushing the camera just made my day!
I'm about to try this on my 55LE5400 before I decide to drop some cash on a new TV.
Thank you!
Thank you very much for share your ideas to us. My tv LG 55" was death and the standby it was on , so i decided to bake my main too, board and my tv it works good now.
THIS REALLY WORKS!!! So many thing on internet are bogus, but this one is NOT! Thanks Jeff Wick and all of you, around the world, who have made videos and commented. My 55 inch 9 year old LG was not connecting to any of the three HDMI ports for weeks now, and yesterday it wouldn't get past the opening page, both of which were problems listed in the comments. A quick UA-cam search got me here. Put the motherboard on cardboard and a metal cooking sheet, baked @300° F for 16 minutes, no bad smell, cooled, (no parts fell off) re-installed and.....WOW! Everything works perfectly!!! Thanks again to all !!
Just did this on a 47LX9500 and worked like a charm. 385 for 10 minutes, let cool for like an hour while I worked on another project, popped it back and video worked. Thanks!!!
spanishsig07 makes my day every time someone replies with another successful bake!
My HDMI ports and sound did not work anymore and there was a green fog on the screen.
Board in baking paper and alluminium foil ( keeps much smell inside too ) for 10 minutes in the oven at 200 C.
Sound did work again but screen totally black.
2nd attempt, the same.
Last attempt, all or nothing, 15 minutes at 230 C, more smell like burning plastic.
Ripe for the garbage I was thinking but gave it a try before dumping the tv.
Everything is working perfect again !
Amazing! Congrats on salvaging your TV and keeping it out of the landfill for a few more years!
I popped the heat sink off of the bgu chip and used a heat gun to gradually heat it up pretty hot (after using caftan tape to secure the components on the other side of the ct bd) reassembled it and it's working!!! Thanks for the inspiration.
It worked for me! I have a LG 47LW5700 which showed a blinking power red light with no video or sound. I first baked it at 275F for 18 min. The tv would turn on and died after a min. I baked it again at 300F for another 18min, and bingo! Thank you so much for the inspiration.
Thanks!, this worked for my 2010 LG 60pk950. I used 285 degree F for about 15-16 minutes. Smell wasn't too bad. My mobo had some plastic cutouts that got melted/deformed a bit, but unavoidable as they were connected to the board. FYI.
update 2/19: mine just went out again so perhaps I didn't bake for long enough to soder the joints completely back in place. Trying again, but I've read that this can only be a temporary fix and is probably dependent on how bad your specific boards issue is.
Found 47LV5500 by dumpster today with same symptoms. Used this fix with minor tweak, and using toaster oven just now at 375°F for 20 minutes. Worked. I'll burn it in a few days and report back. Thanks!
Also, I did used foil to protect the edge connectors, and applied no-clean flux from the outside edges of the BGA until I could see it coming under and through to the other side.
I believe the higher temp would give a better chance of success, with the acceptance of some risk. The toaster oven I used had a convection fan, so spread out the heat some.
I turned the heat off after 20 minutes and let cool slowly. Luckily I had no components fall off. inspection after cool down showed no warped connectors or anything looking charred.
I worried about the few smd electrolytic caps, but I think this method keeps the temp low enough for a short enough amount of time that it didn't hurt, yet hot enough to heat soak the board and reflow the connection(s). Not bad, and quite a nice smart TV, great picture. Looking forward to seeing if it survives a 3 day 'burn-in cycle'. I'll report back.
What a score! Nice work.
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 UA-cam searches I found the baking oven main board method which worked! @ 380 degrees for 10 minutes. Couldn't be any happy.
Just did this today, 13 year old lg 52" WORKS!!
I have a Sharp Aquos with sound issues, the sound would just turn off after a while, tried this and it works perfectly even when I have it turned on the entire day. Thanks dude!
Pablo Mateus Awesome!! Glad it worked for another awesome person.
A tip from other commenters: Adjust the temp to 285 F and bake for about 18 minutes. This seems like a safer temp to ensure the solder doesn't completely melt and drop other components off. Good luck!
This worked perfect on my LG!
Hi Jeff, Thanks for the video. Our 2012 47 inch LG went out and only the slow red light flashing. TV repairman said mother board bad. I put it on a piece of parchment paper on a cookie sheet and covered with parchment and baked for 18 minutes at 285-300 degrees F, turned off heat and left it in for two more minutes, cooled it, installed it and TV worked. No loose solder on parchment. It has been 3 days since the bake and all is well!
LeRoy Winge So great! Congrats!
This worked for me for an LG 55UJ6540...was stuck on spinning dots after a software update. I baked at 300 degrees for 15 min in a toaster oven on aluminum foil over a pan. Solder didn't appear to melt, but it obviously did. Back in action!
Awesome. I love seeing the various tricks and modifications everyone is adding to this process. Glad you've salvaged your TV!
Worked on my 2011 LG 3D TV. Thanks.
Thanks....unbelievable...it works...!!! my tV LG 47LW5700
greetings, still working, did you do something different from the explanation?
This worked for me on a LG 47LV3700. Baked it at 385 degrF for 10 minutes and let cool down for an hour in the oven. I removed the heat sink for the CPU first and put thermal compound on it after heating it in the oven. It took longer to take the TV Off and On the wall than the rest of the procedure.
I used a blow dryer and did not even take it apart. I just pointed it at the vents ports and screen for about ten minutes and then turned it off and back on and it worked !
I did this procedure several years ago and gave new life to the TV. But the same problem happened again so I repeated the procedure and it worked as well.
Sweet! Another winner!!
Thank you! Thank you! It worked with my 42LW5500. 145 degrees Celsius and 16 minutes were the settings. The chip also got fresh hig grade thermal paste. Let's see how long it lasts.
Lasted for 4 months. I bake it again on 155C for 16 mins and works again.
Got a LG 60pk250-US from a local fellow for free. The red light on the front would come up and that is all. Put the main power board and the I/O board on a silicone baking sheet in the oven at 285F for 20 minutes. I have a gas oven so temperature may have been a bit higher. Turned off the heat and let the board cool in the oven. Put everything back together and it works flawlessly. I've been burning it in for 24 hours so far.
Well done - beautiful fam'
Flor tv sir.thanks for sharing.
When you took the board off did it have grease on the bottom and if so did you clean it or leave it? Mine seems to have a pretty good amount of grease on it.
Mine working awesome
Finally! Someone who has DirecTV! Lol.
Hi everyone, I baked for the first time at 150°C (300°F) for 16 minutes and it didn't work ... the second time I baked at 180°C (360°F) for 10 minutes and magically the TV LG32LE5810 started up again!
Thanks a lot Jeff
andrea pollacci awesome! Another success!! Glad to hear you’ll get a few more years out of the TV. Mine is still working.
Do you adjust the temperature for a fan oven? (I realise this isn’t a pizza or a pie, or a cooking channel!😂😂)
I really didn't think this would work. A friend got rid of their lg and I gave it a go, 200c for 10 mins and let cool down for 30 mins and it does indeed work.
It's crazy, but it works!
I just baked mine (LG 55lv5500) in the oven at 285 degrees for 10 minutes and it worked. I had no picture or screen activity at all but the power light was working. Apparently solder softens at 265 degrees
i baked my motherboard in the oven for 10 mins at 375 degrees and now mine works great
Found LG 47LX9500 on the kerb, works except HDMI ports, will try this method soon to make HDMI working, otherwise need to call garbage collectors!
Just to confirm: It works for me. However, smell from the oven was bad. Now I have 47" 3D TV. And please note: 3D Tvs manufactures do not produce anymore.
i have LG32LE5810 with logo stuck... i'll try the bake!!
Does it cause any issue with the oven
Does the tv still work? I did the baking but 30 min after it went back to the same. Not sure if I should heat it more?
Still working over a year later.
Hi Jeff,
so 285 fahrenheit for 18 Min? or 285 celsius for 18 Min?
it sounds like fahrenheit but to make sure I've got the right temp.
Thanks in advance!!
Daniel Cho Fahrenheit. It seems others have good luck with 285 F... hope it works for you too!
Thanks Jeff.
does it works on samsung too?
Anyone had an issue with their older model LG not recognizing the inputs? Thanks for any advice.
About to bake my board for the 3rd time, it has gone out like 1st a year since the first bake lol
Thinking of trying this myself - does the tv still work?
pepplerp It is now 8 months later and the TV has been working flawlessly. Even after far too many hours of children’s eyes glaring at it day in and day out. #badparents haha
I've done this like three times and it works but only for a few months and then it fails again..
My second time baking my motherboard
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 F has brought it back.
I have switched to Samsung TVs now though. Heh
yes this is a temp fix they really need to be reballed.
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.
My only problem is sound, its completely gone out. TV has worked nicely otherwise. MB is currently in the oven 🤞
Hey, don't want to be a downer, but i just tried this on my LG 55" 55UF6450, and its still not displaying video.
I will say that I am AMAZED the TV turned on again, at all!
Baking a circuit board!?!? Are you kidding me!!??
But.. when the board is basically trash, why not give it a try, right?
So I did.
But, with less positive results.
I may also have different issues than are described here, though;
My TV turns on, and is fully functional as long as its on, EXCEPT that all video is "snow".
Very strange.
All inputs, all apps, anything that is video will not display. The audio will work, the menus will show up Crystal clear. But the video behind the menus is snow.
I think it might be an issue with how the board is processing a video signal, not necessarily a broken link/solder/circuit. So that might be why it didn't work for me.
So I await my $250 replacement board (sigh..)
Good luck to everyone else!!
Tony Ricketts Bunmer it didn’t work for you. I’m by no means any sort of electrics expert, but I’m amazed every time someone replies that this trick worked for them as well as it did for me. Good luck with your new board. Hope that fixes things.
LG 55LW6500 - Turns on, no Picture, No sound.
Tried baking today at 180 Celsius ( 356 Fahrenheit) for 15 mins. It worked for a while but soon turned off after about 1 hour usage.
I will try again later at 200 Celsius ( 385 Fahrenheit) for 10-15 min (trying not to burn) and see how it goes.
Hope this fixes the issue permanently.
I will let you know so people can try!!
Hola!!!
Mi TV es un LG42LX6500 ZD, y se me quedó hace un año con la pantalla en negro y el servicio técnico me dijo que era de la mainboard y que costaba el arreglo 250€. Me lo llevé sin arreglar, lo guardé a la espera de pode arreglarlo yo, y gracias a este aporte, lo he conseguido arreglar. Thanks!!!!!
En grados centigrados hay que ponerlo el horno a 190º durante 10 minutos y sin precalentar, por si le sirve de ayuda a alguien. Muchas gracias!!!!!
De nada, senior.
Hola, en el horno, ¿lo colocas a calentar con el calor generado desde abajo o desde arriba, o bien desde ambos lados en el horno?, mi horno tiene esas tres opciones y quisiera saber cuál es la mejor opción. Agradezco tu gentileza.
I'm trying it right now. I have fixed pc graphics cards this way the last one being a Radeon R9 4gb. Bought it from a guy along with the rest of the pc for £400 about 2 years ago. The pc was worth well over a grand . He didn't mention that the pc crashed when playing games , but I still got the last laugh anyway lol
lenny stevens ha! That’s awesome. Congrats on the score!
Can Explain why putting in the Oven?
because it wont dry it out as fast ... you will a nice golden crust... ready for serving !
I baked mine, and it only worked for like 6 six, then it died again. Not sure if I should bake it again, any recommendations?
I would give it another bake. I’ve heard of others who had to do it twice. You’ve got nothing to lose, right?
Did you retry? Curious. I just did mine, and am running it constantly for three days to get some confidence about the longevity of the repair.
Good luck to you!
yeah!!!! it really worked, but now my remote wont work anymore :/
Awesome! Not awesome!
385c or f
Actually, Try 285f.
Im looking to fix my sony but holy shit almost all videos are about fixing LG tvs, guess they fail a lot.
John Doe Yeah. LG fail.
Didn’t work!
This common fault is bad. LG = rebranded "Goldair".
I am a technician for the past 42 years and this does not work. It will destroy your board.
After doing the repair shown in the video, it has been working for well over a year. I've had friends experience the same success.
I am a consumer of 50 years. As a technician of 42 years what do you suggest?
Worked for me.
Worked fine on mine. Definitely did not "destroy" the board.
worked for me.
This process does work. It helps reflow very tiny broken solder connections. Two things though get flux before you do it a liquid version works really well and a q-tip and remove the large heat sink. Saturate every little metal solder connection you can see and then any plastic process boards coat all sides of those and especially the large one underneath the heat sink you want to apply a lot of flux around that which will get soaked into it and underneath it when it's heated. But only a moron would do this in the oven that they cook food in. This is extremely toxic. Go buy yourself a $10 toaster oven from Goodwill or dedicate one you already have for the purpose. I really don't understand how this isn't obvious but I've seen countless of these videos hundreds or thousands of comments and no one seems to think it's a dumb idea. Trust me it is a very dumb idea.
