I have had my Denon AVR 1707 for about two years and today when I started using my Xbox 360 (which Ihave just got back after being repaired for the second time) the amp just shut off after a couple of minutes of play, then I tried my DVD player and it did the same and I had the same thing with my Sky Box. I looked in the troubleshooting of the manual and it said it might be overheating or the speaker wires are touching of course at the back of my Amp is a mess of wires so I tried moving them about but it still seems to be shutting down, is there anything else I can try?
