As said above my tv is stuck on a faint white screen that says set parental control. It responds to NOTHING. I can switch inputs on my tv and watch and do other things on it, it's just the cable/tv input, whichever i plug it in.PLEASSSSE help
Sounds that the Tuner and Video IF section to your TV has the fault. Seek tech support. This is a highly skilled work.

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.

Okay so you have the HDMI cables from both the DVD and the Cable box plugged into the reveiver?

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.
