onkyo 805 not working

[adamh]

Just wondering what to do? I got the 805 about 6 weeks ago and the thing cut off on me this evening right in the middle of playing some xbox. It restarted itself and was fine until i switched to watch a bluray and no sound would come out and while i was messing with it i got no picture too, but it the picture came on after restarting everything. i have everything going through the 805 via hdmi. i have gotten the dts bomb once but when i went through onkyo to get the firmware they sent me the url but when i log on it wont take my serial number even though i could register it. i am thinking it was a mistake getting this from ecost now but if anyone has any suggestions please let me know asap!!! thx ps....it felt a little hot but the unit is pretty well ventilated its in a salamander av rack which is open in the back and vented on the front.
