Check if DTV/CBL is set receive COAXIAL or OPTICAL inputs. Good luck
I have perfect sound on all input components (tuner, DVD player, etc) but I cannot any sound out of the the DTV/CBL (the TV). When any other input is selected, they have a bright red bracket around them but when DTV/CBL is selected, the bracket does not light up. I dont know what this means. I have fooled with input, seems to be OK, but not certain. Speakers work fine. It is set on Auto (not DTS or Analog). Completely stumped.
