As a stopgap, I am using a Denon AVR5700 to provide power amplification for the center and rear surrounds of a multichannel music(not video) system. In the last couple of days, I have noted the Denon's blinking red power light, which I think usually indicates overheating, short circuiting, or just too much power drain. If I turn it off for a while, then start it again, it works OK for a while, but pretty soon it cuts out again. I've checked and am pretty sure there aren't any speaker connection shorts. The fact that it works for awhile indicates overheating to me, although the receiver is not very hot to the touch. Can anyone tell me what kind of cooling the 5700 has? Are there fans which may have failed? I'll pop the lid and look for dust but don't really expect that to be the problem. A month or so ago, when I was using the receiver only as an FM source, I noticed a fairly loud fan noise coming from the unit in short bursts every five minutes or so. Does the system have a two-speed fan or possibly two separate fans? Is it possible that a low speed fan has failed and left the cooling job to be handled by a higher speed fan operating in bursts? I probably need to haul it to the shop but thought someone here might have some information.
