Same problem with component video hookups

I'm have the exact same problem as everyone else, but the difference is I'm using component video. Sounds, but no picture. My HD/DVR and cable box (all-in-one) goes to component video 1, my DVD player to component video 2, and my HDTV to component video 3 (which I assume is video out).

My TV says, "No Signal." The TV works with these source devices on direct connection, but not through the AVR 146. I can't access the OSD menus either through a composite cable. Essentailly, it is as if there is no video output available.

How hard can this be? We've gone to plug and play computer and now we're going the opposite direction with HiFI? This is kind of ironic. Any help out there?
