Got a new issue this time. I left my receiver on standby and went to work (been leaving the unit on standby when not in use since I began using it 2 months ago). Came home and while getting settled, I heard a distinctive clicking coming from the receiver, once every couple of minutes. I thought "that's odd," and turned it on for some gaming. After about 2 hours of play, I abruptly hear the receiver click, I lose sound and picture, the standby light begins blinking rhythmically, and the display goes out. I press "power" on the remote once, and it clicks, but resumes blinking with no change. I press "power" again, and it comes back to life, gives me video (no audio) for about 8 seconds, then clicks off again, with the blinking standby light. I give it a heat check and decide this unit feels *way* too hot. Because of the unexpected clicking I heard coming from the unit while it was in standby, I am worried it was at or around this high temperature *while in standby.* I unplug and go to bed.
Fast forward to this morning. Turn on receiver, get audio and video for 3 seconds, click and power off to blinking standby light. I try with a different input device, and it clicks off even faster.
Normally I run the unit between -30.0 dB and -21.0 dB, occasionally increasing to -10.0 dB for a half hour to show off the high volume during Rock Band. I do have sessions of 14+ hours of extended use over the weekends. Receiver is placed on middle shelf, lots of breathing room on all sides, non-enclosed shelf unit.
Called Onkyo support, they had me do a factory reset, and the problem seems to be gone. Running audyssey now, will post results.
Anybody have something like this happen? Are there tips to keeping a receiver unit from overheating? Should I keep the unit unplugged when not in use?
