AVR335 1 week old. My video source is HD cable box to s-video 2 in. There is no video signal at the s-video 2 out. I also am using component video path from HD cable box to AVR335 then out to TV monitor which is all fine, and I checked the s-video path all the way up to and including s-video 2 in. All good. Is there a setup function or "switch" function to turn on s-video out paths?
