Re: No sound when Comcast box is on.

We had sound for tv. Sound is fine for Wii and dvd. Then we lost sound and picture.

Re: No sound when Comcast box is on.

Do you see the menu's from the set top box, or nothing at all?

 

 

If you don't get the menu's and are hooked up with HDMI, then try both unplugging the TV and the set top box for a minute, then powerup the TV, then the set top box.  It might be due to HDMI hadshaking issues.
