Question about Televison & Video
Turns on but displays dark grey fuzzy screen with a white band, then blank. audio ok
Hello, I need the model number to be of help, but if is a 2006 or 2007 year model it more than likely has a bad "y" sustain board and possibly a bad "x" sustain also. If that's the case I would recommend replacing the set rather than repairing it as it is only a 720p set...tks....Terry

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.

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.

Z-Sustain PCB will cure it.
It is inside the TV, on the Right Hand Side.
www.chsinteractive.co.uk or Google for a replacement.

Most likely cause are leaking capacitors in the power supply, however I've seen the convergence IC cause the same problem. If you have a good ERS meter and are willing to check parts one by one then start with the DC side of the power supply. I fast scope makes this easier. There are a lot of safety precautions you need to be aware of. These are listed in the service manual, which you'll have to have to do this kind of work. If you don't have any of the above then I wouldn't recommend you try to tackle this. Find a reputable repair person.
