Hi there could be a fault on your power supply unit as the high voltage supply drops then the picture will go off as the amp uses the 12v that could be why the sound is still on.
Have it checked by a tv repair man.

good luck

This is a y-board faulure (the part that charges the screen horizontally). They are renowned for this....
