Hi,

If you have stereo connected to your tv, check the wires are cross connected or something like that. It may be a fault from the cables point. To get the digital signal and sound go for converter box.

There may be problem in the internal circuitry of the set, in the audio or power boards. You need accurate diagnosis to determine the board. You can check the sound settings for the Tv as well as the other equipments.

You may have a problem with the main digital PWB. Or it can be a bad power supply. Check the power supply and the connections are proper.
