[qanda]This thread is about the Mitsubishi WD-60735. Click here to see full specs[/qanda]I have a 60"WD60735 TV. I have hooked it up to a HDTV Cable box & I've noted that as my input 1. When I connected the cables the way the manual has stated it gives me a picture but no sound. There are no issues with the mute being on & whatnot. I have a great picture but no sound. When I switch to just the cable 1 input I have sound but not a HD picture. I'm hoping you can help me out with this dilemma.
