I was showing some family that was over Tron in 3D last night in my HT. It all went well for about an hour, running the volume at 69 or so absolute. Then without warning as it changed chapters, the sound completely cutoff. The standby light didnt flash and the receiver remained on. I tried a few things, but we gave up. This morning I got up and tried a few things, hoping the over night cooldown would help it. But nothing. I tried all sources, cable, xbox360, BR player....nothing.
Before we watched Tron, i had the system running all day watching TV as I walked in and out of the room. The AVR was running at 45-ish in terms of volume that whole time. Only when we put Tron on, did I bump the volume up to 69 on avg. I might of had it on 75 at some points, to have the action scenes a bit louder.
So I set the volume to Min, then unplugged the AVR for 5 minutes. After I plugged it back in I got sound again.
So, I fixed it, or so it seems. I mean its even written in the trouble shooting parts of the manual under protection circuit /power section. But I never had the standby light blink at me. I was still a good measure away from max volume. The AVR is in open space for adequate cooling and the top of it didnt feel that hot to make me think of overheating. Has anyone ever seen this happen? Where it kind of went into this "unofficial" protection mode in normal action movie volume situation?
