No sound when watching through EXT (DVD channel)?

Question

The TV works fine but when I try to watch the digital channels (on the channel EXT) or a DVD I have perfect picture but no sound. It WAS working fine. What happened?

Many thanks

Answer 1

Have you tried going into the menu with the tv remote, selecting sound and then toggling through stereo, S1, S2 etc.

Mine did that, and it worked for me.  Don't know about yours though.  Hope I could help.
