I've got an older Denon AVR-1803 that I've acquired recently. Problem is I can only get my monitor to play on S-vid out, no picture on component out. Also, with the monitor connected to S-vid out, I can only get picture on the S-vid in. I can't get any display with my DVD player or DVR on RCA in or component in. I've gone over and over the manuel and can't figure it out. Any ideas?
