My 7years old plasma TV is not having any video but audio can be heard.

The power indication red light is working normally i.e. when off, the red light appears, when on, the red light disappears and audio can be heard from the AV input.

P.S. It had a capacitor bulged in the power supply unit and I had it replaced. Still the problem persists.

Make. Samsung
Model No. PS42B450

probably that bulged capacitor affected a chip or a wire inside it which causes the panel not to work

ahmedkhalifa1999 :

Is there any idea of which board has it damaged? Can it be the main board?

Btw, can a capacitor damage the units of the connecting board?

gladwinsimendy :

it can be easily any board in the screen (they are all connected) but it will be hard determine which one exactly though you may like for signs of burns on them (black spots) or a chip which seems partially molten.
