Privly as much as newone..screen seems wornout
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.

Option 1
If you or your husband have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20. And most cases the new part cost less than $15.

This link sells repacement boards for your TV. If you know which ones the tech said are bad, you can order them and replace the board yourself.
Option 3
Pay $475.00 to get it fixed. :(
I hope I shed some light on the subject for you.
