Question about LG 50PC3D 50 in. Plasma Television
I CAME IN THE HOUSE TO A LOUD HUMMING SOUND ,AND NO PICTURE , I SHUT OFF THE TV . WHEN I TURNED IT BACK ON I NOTICED THE SCREEN WAS CRACKED FROM THE TOP ABOUT TO 1/2 WAY DOWN THE SCREEN NOBODY WAS IN THE HOME SO I KNOW IT WAS NOT HIT WITH ANY OBJECTS AS THE REPAIR PERSON STATED . I TOLD HIM IT WAS NOT HIT BY ANYTHING BUT HE WOULD NOT BELIEVE ME . THIS TV IS ABOUT 8 MONTHS OLD AND HAS NOT EVER BEEN MOVED , DID I JUST EAT 2000.00 DOLLARS.
If nobody at home how was the tv on?!?!?!?!?!? U must have a poltergeist living there if you stick to that story!
Screens do not just crack all by themselves - they need a little help. And product warranty's do not cover abuse. So yeah, you will be eating the 2 big ones.

Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.

sounds like you may have a high voltage arc and / or leak . better to let a manufacturers qualified technician have a look at it this time . ask for an estimate after diagnosis and before repairs are made. factor age plus repair cost v/s a replacement tv . also in the area where i live most in shop repair estimates are cheap or even free . field repair estimates are definitely not . all tv parts can be replaced but, screen replacements can get expensive . barring neglect , abuse or a significant power surge you should not be having these problems on a tv so new. double check your warranty. most electronics come with 1 year on parts ,90 days on service. some warranty limitations are not allowed in certain states. also contact the manufacturer . in my expierence some of the better companies have honored an expired warranty partlialy and sometimes even fully on a relatively new product . after all they do have reputation to lose or keep . just be courteous and if your lucky they will be too. but if all else fails, i personaly prefer lcd flatscreen . oh , about the screen crack , clean and position your tv according to the owners manual . some of todays televison components are even more thermaly and chemicaly sensitive than ever . ie; window cleaner can whiten or even crack certain types plastics. finaly if you are not using a good surge protector now may be the time.

call 877-543-8325 this is an LG Executive call center and they will fix this for free. I have a 50" plasma I bought january 2006 which is out of warranty by 5 months. They faxed me and the LG repair shop a 30 day warranty for my tv to cover the repair. Just tell them you heard a pop and in my case the picture is distorted. All they need is the model number and serial number and they should take care of it. No arguing needed.

Hi , I recently had the same problem which I was determined to fix . So I did a few weeks of research to find that it was the Y SUS board which burns out. I'm sure you realized that the TV gets hot. Personally I think this is why. circuit boards don't like heat and I've learned that the cooling fans are a joke. I replaced the board and got my picture back. I proved the fan theory because after the screen started to act up. I placed a cooling fan near the vent holes on top and the problem cleared right up,It also helps if you lower the brightness which helps out on the heat situation.I will soon be adding a fan with a temp. sensor. This shoud help if your screen has lines when you initially turn the cool TV on.then I have Some other costless solutions. Hope this helped these are great TV's and like our cars we maintain them not throw them away..................................Mr Wiseman

This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.
