So, I have a 1611. got it hooked to directv and a bd player and using a 5.1 system; used audyssey to set it up and got everything going, but so far I've had it turn itself off twice in 2 days; once while watching directv and once in a bdmovie. First time it happened after 45 minutes, the second one after just 5, both times I ended up with no signal on tv and I couldn't just turn it back on, but had to turn everything else off and then back in order to get it going, and both times after it happened It went back to working normally after I decided to turn it off.
What could be causing this? What should I do to troubleshoot?
For the past 3 months I had been using it in a different room just for radio and ipod with no issues
