AAAAARRRRRGGGGHHHHHH!!!

I just finished setting it up, listened to some DVD-Audio, a CD, tested surround modes with Shrek, got pretty good FM reception, got used to the remote, and there was a click and everything shut off.

I'm going to bed. I'll look at it tomorrow. Any ideas would be appreciated. I think it will be very inconvenient if I have to disconnect it and take it out of the rack after each 30 minutes of use...
