Denon AVR-2311CI protection circuit
I recently received a Denon AVR-2311CI receiver that was supposedly new and unused (still in the box). I know these are about 6-7 years old now, but it would be fine for my basic home theater purpose. I unboxed the unit and plugged it in, but after a few seconds it shut down and the light around the power button blinks red. This is supposed to indicate that the protection circuit has kicked in. I tried a microprocessor reset, but the protection circuit still shuts it down. According to the Denon support person, having no speakers attached should not cause the protection circuit to kick-in. I opened up the case, and if I disconnect the plug that feeds the amplifier board, I can start the unit up and it stays on.
I called some of the factory service centers to see if this is a quick fix, but got the standard reply that I need to ship it in for evaluation (after paying money up-front), and then any repairs would be about $120/hour. Don't really want to spend a couple of hundred dollars to have an old receiver fixed (even if it has never been used). Thought I would check here and see if anyone else has had this problem on their Denon receiver, and if they know what caused the failure. I thought that it just may be a simple component (capacitor, etc.) that failed because it was poor quality.
