That problem is caused by the Y Sustainer board.

Sounds like it could be a display board problem or the display itself.  same happened to my 50hp82.  i was quoted 450-800 for the display board.

SOURCE: No picture, sound works. Screen flickering

It sounds like the video output isn't
working its most likely a component
failure 1 thing you could try is connecting
a rca cables from video/audio out on the set to
another set vid/audio inputs to see if it the video gets
through.This is a problem that requires technical
knowledge and test equipment to trace the video

Lg plasma tv screen flickerin


HelloThe problem shows the refresh rate. Quite propably that you are seeing the much slower beat or heterodyne. Often caused by artificial ambient lighting like florescent tubes or faulty dimmers on halogen's etc causing the beat with plasma screens.

Otherwise you need to check power supply
