Totally sceptical about this. Was none too gentle taking my LG TV apart as this wasn't going to work, I had my new TV picked out already because baking bits of your TV in an oven is never going to work, surely. THIS ACTUALLY FIXED MY TV! It was very simple from start to finish under an hour and £500 saved. Thanks!
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!
Unbelievable! IT WORKS!! My 55LE5500 wouldn't get past the startup screen yesterday but it works fine now! The kitchen had a hot electronics smell for a few hours but was OK this morning. I had my doubts but figured I had nothing to lose by trying it. When the startup went away and the logo screensaver appeared, it was fantastic! I actually yelled out loud!
Wow. Just done this with our 49inch LG and it has worked a treat. I think we've had it 6 or more years so well out of warranty and probably not worth paying to repair but this has done the job. We'll see how long it last for but even if it's only a few more months or weeks well worth the minimal effort. Cheers for this original post.
Baked my board at 250, 10 minutes... let it cool down for 20 minutes..HDMI now working again. Thanks for the share.
Just worked perfect to my LG 32" which stuck on start up!!! Many thanks!
Worked for my TV for The 2. Time : )
The First Baking repair was 4 Years ago and now it worked again
I was a little hesitant about trying this but......HOLY CRAP THIS ACTUALLY WORKED!!!!! HAHA!
Got my LG 55LE5400 working again :D
THANKS YOUUUUUU!!!!!!!!!
+Ham Fitness glad it worked!!!
Ham Fitness yeah it works ...amazing
Same. ..it works amazing. ..
Tried last night, works a charm on my 6 year old LE7900! thanks!👊
It really worked. My LG was stuck on start screen as well. I cooked it for 10 minutes ia a fan assisted oven and is now working. Will see fo how long though. Thanks
+Mladen Borisov great news!
Just tried this and it worked set oven at about 380F for exactly 10mins and now my TV is working thanks.
many thanks.My lg22"monitor- tv fixed.before No display,only sound, now it works perfect again.
It worked for me too. My LG42le5500. Thanks for sharing this.
Same tv and about to try now lll
I trayed on my LG 32LD650 .....and it works. ..amazing.. thank u guys all of u with your advices on yt ...it works
You’re a legend thanks buddy! I really didn’t have much expectation that this was going to work, but it did. Back playing Fortnite now lol!
Thanks, I got an high end LG from 2015 and it had this issue with HDMI.
I first tried an hairdryer for first 1 min, then 2min then 5min and it didn't help, baking at 200C for 10 minutes on paper towel and then waiting for it to cool down worked for me first try.
Cheers
Thanks for this! We have baked three times now. Buys about 3-6 months each time. Why waste an otherwise perfect TV? Repair guy told us it was not fixable buy a new one.
just done it to my lg works perfect thank u so much I put mine in turned on oven put it on 200.. for 12 mins .
+Riley Depp glad to hear it!!!
Had the HDMI ports not working problem. So i gave this a go, at first it didnt seem like it worked but i noticed that i hadnt slid the Ribbons back into place properly. Works great now im buzzin
Haha did this dis-morning on my 2grand 55inch lcd which died last night (had it for like 6+years), and were working and running well! I did it at 210-225c and I melted a couple of the Component ports but hdmi is working fine so all is good, Cheers for the Video man appreciated heaps! :) hopefully it continues to work I dont have money for another TV aha.
From the Greal lands of Straya also
Watching from my fixed tv, thank you!
You can add an old dead telly to the list of repaired via this route. many thanks. 200c, 10 mins, put a cover over it as was paranoid about the fan over air flow being more likely to melt some plastic component. Smelt a bit, but all good it seems!
Excellent. TV fixed. Thanks for video.
Cant believe it just tried this and it worked, amazing.
+BashDynamic great well done
Hola. Cocine AL HORNO, la tarjeta a 200 Grados Celcius por 12 Minutos sin precalentar. Y RESULTO!!!!!!!!Quedo funcionando. Tenia el síntoma de que se quedo pegado en el logo y la hora... MUCHAS GRACIAS por tu aporte, si no hubiera visto tu video habría comprado un TV. GRACIAS MIL.. De Santiago de Chile...
That worked! I baked mine for 10 minutes at 320 Fahrenheit.
This hack worked for me and got my 55in led LCD tv repair after it got stuck at LG logo screen. Set oven at 350f (targeted for 385 because it runs hot and is old), after preheated, placed motherboard on piece of cardboard and baked for 10 minutes, after 10- turned off oven and cracked open oven door about 1 foot open to begin cooling for 10 minutes, then opened oven all the way for 10 minutes. After, removed from oven and set on table until cool to touch, then reattached it.
Smell: yes, it smells bad, but i didn't have as much smoke and fumes as it looks like this guy did. Kids were in bed sleeping and it didn't go upstairs- we opened a door for fresh air, and turned on a bathroom fan. It was less powerful than food that falls in the oven and burns. It was a "hey- I can smell the solder now" strength. Not worth worrying about doing it outside, just make sure you can open a window or a door for fresh air.
Thanks to everyone for your help! Pay it forward.
Model number 55le5500
+Objection Kat great work man!
Nice video and explanation of the process. I only recommend that this is not done in a kitchen oven as the solder in the braze does contain toxic materials that can deposit on the internals of the oven as it's being heated.
it actually worked. thanks.
the question is how long it's gonna last, but we'll see..
That's great. Hope it last long!
Is it still work
Jux tried it out .. it works perfectly !!🇬🇭
Wow! It totally worked!
What kind of sauce would you recommend?
😁😁😁😁😁
Mind blown. I thought that I was getting pranked the entire time I was baking the circuit board at 400 degrees F. Now my HDMI inputs work!
You posted your repairs in 2016. Is the TV still working?
Is it still working
I am about to try this tomorrow on a salvaged LG 42in Ld550. IM HOPEFUL now. A New board is 104$.
+matthew Adames good luck!
Instead of using the kitchen oven, use a toaster oven and do it outside... Save your house from the stink!!!!
just remember that 200C is about 385F... solder melts at about 365F... if you place it on cardboard and go above 451, your cardboard will burn
Do i have to heat up first the oven or i will put the motherboard at the same time i turn on the oven and wait for 10 minutes to take it out?
He mentioned to Pre-heat it to the 200f.
Only man can bake technology. Recept? You her it, may works may not. Let's bake.
wow I was very skeptical> but my 6yo LG wouldn't power up.So I was Quoted $400 as a repair ..or just buy a new one. either way no more LG for me ...will just buy a cheep machine next time . they will last just as long for 1/3 the price. ( its amazing that the LG machines seem to shit themselves just after the 5 years ) So I stuck it in the oven at 200 degrees C for 10 minutes and bloody hell it worked , even in Australia
+Katrina Kemp Ahhaha that's Great! Your right it's kinda pathetic that we have to go through these steps after a few years. I'm glad it worked for you! "even in Australia"
Can we do with this my lg 32ls3400 tv board?
+rajibur rahman probably
8 monts after baking and hdmi ports are dead again. how you think guys 2nd time is posible to bake ?
is possible this metod in mother board on model LG 42LB670V ?
So i baked the motherboard and it seemed to work but then the left side of the screen was white, i turned it off back on and it was stuck on logo again and the screen was still half white, any ideas?
Where can i buy Main Board for my Lg 58'' (LG58UF830V) Tried the baking method but it didnt work.
Ebay is ur best bet maybe. I got one from there
Could this work for my phillips
Tried it, didn't work..say goodbye to a $2500 TV :(
Hi Aim. What are the symtoms/problems you have with your tv?
I do this all time oven temperature sure be 350 degrees but aluminium pan bake 15 mim. and turn off oven and crack the oven door. let sit in over with door crack to the oven and board cool down complete do not get board out or oven temperature complete cool down it reflowing
Aim Dawson
tell what TV you have I can fix from here send model number
Super set ok
My lg TV 32lg5500 is stuck
tried it. Now the display is even gone. Black screen. worse that it was before. I wonder lol.
That did not work for me. After baking the mainboard, my 2017 LG 65SJ8509 Super UHD LED TV is still stuck in a boot up loop as you see here: photos.app.goo.gl/hqRjBo7VgQPwov3T6. Maybe the fault is in the power supply board?
I did this and it didn’t work . I even waited a day and did it again and it still didn’t work
I tried everything...,all those steps,.Didn't work 😭
These kind of bakings is similar to playstation and graphics cards oven tricks.Not a permanent solution and the same problem arises soon.
Here goes, just put it in the oven wish me luck
