My husband was watching television, left the room and when he returned he had no sound - there is sound throught the DVD player, but not through the video or television...our television is a simple Magnavox, not very expensive....did our cats step on the wrong button on the remote and we just can't figure it out?
Go into the menu and check the SAP section of the sound and make sure that it is on normal TV. See if that helps. If not, unplug the TV from the wall for a good hour or so, plug it back in and see if that helps. Good Luck
