So just recently my Onkyo receiver has been acting up and turning itself off. It appears that if I push the receiver over a volume of 50 it will act like I turned it off and the Standby light will start blinking red. I've read online that it has something to do with overloading the receiver, but I'm not sure how that could be since it's never had the problem before and I'm also not sure what to check for.
Update (04-14-2009)
OK, after extensive troubleshooting it appears that my left speaker plugs cause the random shutdowns. It doesn't appear to be the physical speaker or the wiring as I can swap the cables/speakers to the right and they work fine, it isn't until I plug anything into the left speaker plugs that it starts acting up. Also, initially it seems to play fine and everything is good until after like 10-15 minutes and then once it starts happening it is almost continuous; almost like once it warms up it messes up the left plugs. Right now I have the left speaker unplugged and everything has been working for the last 30 minutes or so. I don't have a small fan, but plan on buying one to see if that helps, but don't like the idea of an ugly fan in my entertainment cabinet.
Update 2 (07-19-2009)
Argh! I'm so mad right now... I sent back my receiver to "Jersey Jim" in Clearwater, FL (the only one near me) a week ago before I went on vacation and I just got back and they shipped me back my receiver already. I was pretty happy to see that I got it that quick and quickly opened up the box only to see taped to the receiver a note that says 'check speakers and cables for a short'. They didn't call me or anything to discuss what the problem may be or for me to describe it more in detail if they didn't understand.
So I wasted $30 to ship the receiver to them and now I have to call them tomorrow and figure out why their customer service stinks. They better pay to have me ship it to them again.
Update 3 (12-11-2010)
So over a year later and the receiver is exhibiting the same behavior as before... instant turn off after a few minutes and the HDMI signal is now "flickering."
Trying to decide if I should try and get it fixed again (but this time not under warranty) or just get a different one. If I get a different one, not sure if I feel good about staying with Onkyo... Have they gotten better with overheating since my model?
Update 4 (12-12-2010)
I think I'm ready to cut and run... I don't want to run into this again next year and have the same dillema. And last time I fixed it, the one Onkyo repair shop by us took three months to fix it!
So based on my setup above what would be a good receiver for me? It would be nice to have pre-outs, but not critical if it doesn't.
Also, do the higher-end lines of Onkyo have heating issues or should I begin to look at other brands... Pioneer, Denon, etc? Do the other brands have equivelant setup wizards and stuff?
Some receivers I'm looking at so far in the $300-$500 range:
Pioneer VSX-1120-K 7.1
Onkyo TX-NR708 7.2
Denon AVR-791 7.1
Yamaha RX-V667 7.2
