Denon 500 cutting out

[Horsefruit]

I've just purchased a Denon 500 and spent the evening setting it up. After following the simple initial set up I inserted a cd and noticed that every 20 seconds the subwoofer and centre speaker were cutting out for about 5 seconds. This continued to happen when I played a dvd, but then after 20 minutes or so of the film the cutting out seemed to stop. Has any one else experienced this? Other than this, the sound and picture are superb.
Cheers.

No it hasn't happened to me. If it did I think it would disconnect everything and reconnect it just to see if that made a difference, then if not report the fault to the seller straightaway.

Never happened to me before. Definitely sounds like a fault. I'd go with Wicket and report it straight away if the issue persists.
