Question about Audio & Video Receivers
Its one of Three problems. The main b+ filter is defective, one of the standby power sources have a bad capacitor on the line, or theres a short in the main amp. section. Its probabvly going to cost you more then you would care to invest in a reciver thats around 5 to 6 years old. Its most likly time for you to upgrade to a suround sound dydtem with new fancy lights bells and whistles. Good Luck

Sounds like you have a "nuisance shutdown", caused by failure of the speaker protection circuits which are notorious for problems. Unfortunately, more and more newer electronic units fail this soon. It's not really the manufacturer's fault, it's more that individual electronic parts have gotten cheaper to compete in the marketplace, and are more likely to fail than in the past. Unless you used to play the receiver really cranked up (which would suggest failure in the output circuits), you have a nuisance shutdown problem. At any rate, I would question the circuit design and probably buy a better brand (such as Denon or Sony) rather than take the chance of spending money and having it fail again soon. Just my educated opinion (technician for 35+ years).

This is a logic problem with the internal microprocessor. A quick experiment: Turn the unit on for about 2 minutes and shut it down. Doe sit power uip in this case? If so, I'd suspect that the heat generated during normal operation is creating an internal problem thaty is preventing the micro from recognizing the "off" condition. The power data line is hung and is not being recognizwed by the micro so any attempt to turn the unit on will fail. The unplug/re-plug essentially clears or resets the unit.
If the unit is new, return it for warranty repair. It will be important to describe when the unit fails however. Try to see how long it must remain on for the problem to occur.
Update this with your results if the unit is not under warranty and we'll try to narrow it down.

I have an HK AVR140 all of the displays work, even shows when a digital connection from the Blu-Ray player is connected but no audio comes from the speakers! I found some information that HK does not have DC protection so when there is a problem muting Circuit is initiated on the main Amp. I called HK and they want me to send it in to a service dept that is not close at all. Any ideas? Or is there a way to by-pass the muting circuit somehow?
