Having some problems getting my receiver to work how I want it to. When connecting hdmi's and components to it, it doesn't seem to be outputing them to the screen. Similarly when I connect an s-video cable to it, needed for the on screen setup, it also doesn't display. Well it sort of does, I can see the faint writing sort of flickering in the background, but nothing clear or steady enough to read meaning I can't set the receiver up. Anybody got any suggestions?
