Your connections all seem to be fine. It is possible that you have a bad interconnect. Can you hear the sound, but not see the picture? If so, your video interconnect is likely bad. Try using the cables from your DVD to test. You could also try moving everything to Video 2, to make sure that you don't have a bad input jack.

I don't think it should matter, but try disconnecting the S-Link cables, and so your switching manually. Any luck now??

keep me posted.
