LG PLASMA TV MADE A LOUD POP NOISE NOW PICTURE IS SNOWY

capacitor on power board needs replacing

Probably filter capacitor in power supply if it
exploded should be easy to find may have caused other problems however
could be worth checking

probably the pop was a fuse blowing inside that only controls the lamp should be an easy fix but open the tv at your own risk

Ur tv have burns capacitors,look for pop ups caps.

The most likely the TV has a power supply related problem. A power surge can cause the problem. Last thing you want ot do is void the warranty by opening up the TV. Here's info to get your warranty started:

The plasma gas tubes may be damaged or the gas couldve leak out. remember plasma have to remain upright at all times even when transporting them, if they are not you should just set it up straight for about 3-4 hours before turning it on.

Plasma tv's don't last long....buy a led tv.

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.

The popping noise you heard it's probably a capacitor blowing up in the power supply circuitry. If the TV is less than one year old, still covered under manufacturers warranty.
Let me know if you need any more assistant let me know.

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.
