Fixing my LG TV... by putting it in the oven

- My LG TV (LG 60PK590) stopped working yesterday. While it seemed to recognise HDMI cables were connected, it was refusing to 'connect' and display an image. All the HDMI inputs were suffering in this way, even with different input sources. The VGA and SCART inputs seemed to be unaffected.
I found this website zedic.com/lg-42dl550-fix-repair/ which suggested baking the mainboard in the oven at 200°C (392°F) for 10 minutes. So I followed the instructions... and it worked!
I decided to record the process to give others some confidence in doing the same to resolve the same or similar process.
You do this at your own risk, and cannot be held responsible for any damage or harm caused by following the same process. If in any doubt, hire a qualified engineer to help repair your TV. - วิทยาศาสตร์และเทคโนโลยี
I have a 60" LG 60PM6700 Plasma TV, 12 years old, with 4 faulty HDMI inputs. I baked the main board at 390F for 15 minutes, voila!, works. Did make a stink that lingered in spite of opening a window and running the stove's exhaust fan and some of the plastic around the RCA connectors slightly melted.
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 news! Glad you got your TV working again!
I have a 2011 42” LG 42LE5500, symptoms were horizontal lines across the display and not picking up input from any source. I came across your video after searching for 2 days on finding a replacement main board or a place that repairs logic boards. The part for my TV is obsolete and had no luck. So either way I was at the end of my options.
Tried this fix and IT WORKED!
Removed the board, popped it in the oven for 10min at 190 degrees Celsius, allowed it to cool down and reinstalled into the tv.
Thanks for the fix!
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!
Yes, this worked! 10 yr old 60” plasma set with hdmi glitching - baked at 390F for 10 minutes with a 30 min cooldown. Worked!
Hi, first of all I want to thank you. My 60" LG Plasma had the same symptoms. My board was different and it was not available for me to remove in that fashion without having to buy new parts. Of course buying the new parts would have been risky on something I was not sure would work. So what I did instead was to get a small cube heater and position it directly behind each of the 2 boards on high heat for 20 minutes. Well when I was done I did not reattach the backing of the TV I just tested to see if I could get the LG logo back up on my screen. Well much to my delight, there it was. I am now watching a little golf and I owe you for giving me the idea. I did not video it as it was a lot of work lugging that old plasma up and down for me. I hope this helps someone else. Thanks again and again and again for sharing, I would have never tried what I tried without you. Have a Happy Easter.

It's January 2020. And I'm excited --- your video just helped me to bring back to life my 10 year old Sharp Aquos LC-55le620ut. I mostly used your method with minor modifications:
- preheating the oven to just 350F (177C)
- wrapping my TV mainboard in tinfoil all around and putting it in a tinfoil tray
- I placed it inside at about 150C while still preheating
- after reaching 177C - I kept it in the oven for 7 minutes
Voila! That was sufficient to resolder whatever bad connection. It didn't even smell.
All glitches are gone, my Aquos is Made Great Again!
I would be worried that the tinfoil would cause reflux away from the board. That said, congrats! HNY!
Hi Max, woulld like to hear some updates on your repair. does your tv still works?
baked mine in the oven for 10 mins at 375 degrees and now mine works great
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!
Thanks a bunch! It worked!! I was really bummed out 'cause the hair dryer method didn't work, then saw your video, really appreciate it.
we did this by putting our whole tv in the shed on a super hot day and it worked for us too....we will have a video coming out about it soon....
Amazing result! Beware though ... when eating your Christmas pudding .. you just might find that missing screw 😀
thegoldenorc I half expected to hear it rattle inside the case as I remounted it, but no. I was very careful about carefully putting the screws one by one into clear cups. Really odd. But like I said on the video; it's not a game changer!
thegoldenorc pudding is put in the oven? OHHHH the pudding must not be working right
Had the same Issue but since I have a model with plastic covers on the motherboard, I put it in the oven at 90° only for 30 minutes and it worked aswell !!!
worked!!! on my lg 47le5400 i removed heatsinks and baked it for 15 minutes
You saved my life, THANK YOU.
I just tried this AND it worked!!!! Thank you so much for sharing
So pleased for you. Lots of people tell me they wouldn't have the confidence to try. Glad you did!
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.
the fix has stopped working. I will have to do this again. so it seems that this fix lasts about 8 months before needing to do it again
Totally worked for me! So pumped.
Worked like a charm!
Nice!
Woo brilliant happy ending!!
It's working....thank you
Thanx body!!! Its working!!!
Brilliant JJ - A nice Golden brown ;)
Worked perfect for me - LG 47LX6500 - tumb up
This works. My hdmi ports stopped working and baking it in the oven made the ports works.
after trying the oven method my tv didn´t turn on. I tried with a new mainboard replacement and now it turns on but there´s no image. Any ideas? thanks a lot in advance
Dude I did it and it worked. Em ke alarms went off tho .. BUT IT WORKED
I did this and hdmi is working but I have no sound through hdmi now not sure whats going on
Mine is starting to go out apparently hdmi 1 and 3 works but hdmi 2 is not working anymore I guess I wait till all 3 go out
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.
See what I had to do, it might save some steps.
Sadly didn't work for me. Thanks though for giving me something to try.
U have a nice oven ngl
Jonathan 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.
Grease I would remove before heating. Mine didn't have any IIRC.
It seems this TV is weak at the HDMI connections. I have done this 4 times, pulled the board today for a 5th. It seems to blow up when I try to use a Firestick or Chromecast on the HDMI port for very long. I was able to get a longer duty cycle this time by putting my Firestick on HDMI 1 instead of 3 but alas here I am again.
Wow, you might be right. I seem to have had the problem after switching back and forth on the HDMI's to my Android box. Good share for others to read. READ WHAT KEVIN JUST SAID, IT COULD BE IMPORTANT. Me I am going to use the Android box on my Panasonic upstairs, it never seems to have issues.
Interesting, when my TV stopped working I was watching something on Chromecast and fell asleep, the next morning it was still on, then went to the bathroom and there it was, the "no signal" message, I got cc about two months ago and my TV never behaved like that before, now this weird thing happens every now and then when I switch inputs the audio is gone unless I have to go back and forth inputs to fix it.
REMEMBER TO REMOVE ANY HEATSINK AND THERMALPADS (HE DIDNT) BEFORE U DO IT
Help needed!!! I have a similar situation with my LG monitor I'm able to see a black blank screen, when I connect my laptop through HDMI and I'm able to hear the audio but no video. Any idea this method will work with monitors? and I have a microwave oven. Is it any different from the oven you have? Should I give it a try?
Microwave will NOT work. You'd get a wonderful fireworks display if you used a microwave with this process.
If you can use an oven (fan or convection) then i would say give it a go. What have you got to lose?
@@JonathanJenkyn Haha I don't want any fireworks for sure. Do you think Hair dryer would be a good option? If so how long should I blow the motherboard? First of all I think all the oven methods I see in internet is for tv, can I safely assume it's the same process for monitors as well?
@@thanish1991 hairdryer won't get to a stable temperature and won't be hot enough either. You really do need an oven. Should work for many electronics where the solder has dried up.
Dude my motherboard scart connection molted in the oven😂😂you should of warned smartass. I only put it af 180 celsius for 8 min. How did your scart not even melt. Impossible
"LG" = "Goldair" renamed. Pretty ordinary given that this issue (whatever it is!) is so common.
LG=Lucky Goldstar.
Hi, this process worked for me. Someone who has done the process and tell us if the problem came back later?
It has failed again for me. Bought a new telly, but still have the broken one, so will see if a reflux solves the issue again.
@@JonathanJenkyn How long it was without failure?
@@jaimeluna1162 9months
Thanks
He sets his oven for 200 everybody else says 380 to 385 which is correct
200 degrees centigrade = 392 degrees fahrenheit
Piease sent new video
Can Explain Why putting in the Oven ?
Probably cleaned up of dust and moist.
Melts and re solders the connection with the heat from oven
It reflows dry solder joints. This usually happens because of low to no Pb solder that's used in modern electronics. One might say they're being eco friendly, but when you're throwing away tonnes of tvs, I'm not sure its that green.
A HOW TO on removing all the shit from the board would be helpful
... and 9months later, and the TV has died :(
There are people that have done this 3 and 4 times though. A little work, but still cheaper. I will never buy an LG again though. This is a problem right across their line ups and they should have a forced recall as it is a defect, that seems a little to convenient to forcing people to buy new TV's. Planned obsolescence comes to my mind.
Just do it again. Faster and cheaper than repair or even going out to buy new. I did this a few times to my Xbox 360. Great video.
I've baked it again recently, and have a lovely new mega-monitor for my office ;)
@@JonathanJenkyn I'm curious what you mean...did it work after the second time or not?
@@louf7178 Yes it did! In fact it's worked 3 times now! th-cam.com/video/yP9Tava3z4c/w-d-xo.html
tried it waste of time dont work
Sorry to hear that bud. But you didn't lose anything in the process.
Play mikroval😂
My husband did what you say, we put it more than 30 minutes may be hour, after that my tv started to burn!!!! then we call the fireman!!! fucking english!
Lol brainless idiot where in the video did he say 1 hour?
