Thanks for the replies fellas.
Yes, I have disconnected everything, set in a wide open area with plenty of ventilation and done the cpu reset but it still does the same thing.
It is under the Denon 1 yr warranty, and from what I've read should be fixed for free minus postage...I hope. I've been calling over the last 3 days but just don't have 45 minutes at work to wait to talk to them. Tried leaving an email which didnt really get me anywhere either.I want to get this damn thing fixed, but want to talk to someone about it first, thats the frustrating part.
Wish I had bought the Onkyo 605 now...D'oh
