Just connected Vizio HDTV to DCT6400 cable box provided by Comcast and no longer have sound. Would like to see diagram of proper connectivity or set up guide to find resolution.

Homes,

Are you also using an AVR?

How did you make your connections to the TV. Are you using HDMI cables, Picture and sound. Component, Red Blue Green, video only, High Def. or Composite, Yellow- video, Red White - audio?

If you are using RBG, then you still have to connect your audio lines.

Of course, the simplest thing to do would be to make sure someone didn't accidentally mute the cable box or TV. :)

It might be possible that you have not connected the cable box properly to the Vizio HDTV. According to my information, I know that Vizio HDTV works amazingly and provides reliable performance. New HDTV Technology reviews indicates about the popularity and efficiency of Vizio HDTV
