Sounds like a main board or a sustain board problem. This is most definantly not a repair job for the consumer to attempt. Please call in someone who is experienced with Plasma TV sets, as these boards can be very very expensive. Too expensive for you to guess and buy and then have to order the other one. Oh this model also has some power supply issues as well. Good Luck

Plasma displays do not have backlights. The ionized gas (plasma) in the pixels is the light source, just like a tiny neon light. If your screen is dim or blank, check the high voltage supply that ionizes the gas.
