Does seem a little odd for that series of Yamaha to have amp section cutting out, just the one set of speakers, the mains I presume?
Also wondering do you use any video upscaling in the avr when it is cutting out? I doubt you are as not many do, but those video chips have been known to create lots of heat when in use which will cause shutdowns.
No upscaling.
Only front left.
Both times after watching a movie and about an hours worth of 2 channel listening after the wife went to bed.
The reciever showed no signs/codes/smell/heat just no audio from that speaker.
Since getting the amp I've watched many movies and never had a problem. Its odd but...
