Forgive me, I'm probably doing something stupid, but I need help. I'm trying to set up my new Denon 3802 and speakers - this is my first HC system. I had read somewhere that you could set up the amp without the on screen menu, so I didn't bother to buy a cable to connect video. Looking at the manual now though, it clearly needs it. So rummaging around I found a 3-phono cable that shipped with my DVD player (2 audios and a video), so I plugged the video lead in the front AVS socket of my Loewe Vitros and in the video monitor out of the Denon. On the TV, I set the AVS signal, trying a few different options. When I switch everything on I get a brief view of a small menu at the bottom left of the screen, but it soon disappears and the screen goes blank. I get no response pressing the setup button on the amp's remote. I'm not completely convinced the amp is responding to the remote - it doesn't do anything to suggest it's picking up an IR signal. Am I using an inappropriate cable? What signal format should I set on the TV? Or should I be worrying about the remote? I can't get started because I can't get past the first instruction - "press the setup button".
