I have a 4yr old LG 42PG60UR-TA plasma TV. There is no picture and only sound. When I turn the TV upside down picture re-appears but only for a short while. What could be the problem?
The problem of your plasma will be in hardware
you must contact to a led or plasma repairer otherwise its not possible
SOURCE: 42 inch LG Plasma TV - Lost picture
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.

I think you have a defective power board. the pop sound in coming from the board and giving you a low output voltage. do it yourself price about two hundred for parts.
