We have a new Vizio Smart TV, a Panasonic blue ray player, A VCR, a stereo receiver, and Xfinity Cable Box. The sound works fine on TV and VCR. However, sometimes when we put a DVD in our player, we get video but no sound. It's weird too, because if we hit the first notch of fast forward, we will get sound - speeded up a bit, but on regular play, no sound. We thought it was our DVD discs at fault, but there must be something else going on. Any help?
I did what you suggested and it is now working. But it has worked off and on before, so this could be just one of those times that it will work anyway. But, we'll see how it goes. Thanks for the suggestion.
