I have a Denon 1612 receiver that keeps going into protection mode when I turn it on (red flashing standby button at 2x/second). I can then turn it off an back on again and it starts fine. I checked all speaker wires with an ohm meter and no shorts. Also no shorts at receiver terminals. The only other option is "amp failure".
What exactly is meant by "amp failure". I can't see it as a failure if it starts right back up again. it only happens after the unit has been off for 4 or more hours. Unit is used daily and purchased in May 2011. Issue seemed to happen more frequently over the last few months and now happens with every start.
Is it worth trying with no speakers attached? The only thing I can guess is the power supply filter capacitors are bad or the sensor that detects overload is triggering too easily on startup (especially when the filter capacitors are starting from empty).
Does anyone else have experience with this? Suggest how to DIY a repair?
No Denon repair centers near me so ignoring the problem or a DIY fix is only option.
