i am a very new newbie. i have a scientific atlantic digital cable box with coax, and s-video. my tv has a s-video jack, and my receiver has s-video inputs with monitor out, and has a coax input. how do i hook my cable box, tv, and receiver up using these inputs properly. right now i have the cable coax going to the receiver, which gives me digital sound on the digital channels,but no sound through the receiver on the analog channels. i have the s-video from the cable box going to tv in on the receiver and the s-video monitor out going to the s-video on the tv, but i get no picture unless the receiver is turned on. what am i doing wrong? the receiver is a panasonic sa-he 100.
