Question about Denon Audio & Video Receivers
My receiver is blinking in standby - when you hit the on off button it comes on but then reverts to stand by - what do I do?
It's going into protect. Unhook ALL the speakers and see if it still shuts itself off. If so, then it will have to be taken in for service.

sounds like overload protection
turn the volume all the way down, then turn it on
if that doesn't do it you may have a short in one of the speaker lines - try disconnecting them one at a time

I have a Denon AVR1708 and a Denon AVR687. Both had this issue and the issue is related to high temperature usage; like if the unit is in an entertainment systems with poor ventilation. I was able to fix both fairly easily. The issue is related to the voltage regulators on the power supply board on the 1708 and the main board on the 687. In my case, I had failures of the -15 volt regulator KIA7915PI. Both I believe were related to high temperatures.
You can get the regulator for as little as 50 cents at some online stores. The job on the 1708 was easy, however, on the 687 it was a bear. It took about 1/2 hour on the 1708 and 2 to 2 1/2 hours on the 687. The component is a lot harder to get to on the 687. The component needs to be unsoldered and removed and the new component soldered in. You will probably have to remove some caps to get go access. Thermal grease should also be applied to the new component.

Did you try to reset the unit? Resetting the unit has fixed every problem I have ever had......turn off unit.....hold down A+B at the same time then turn the unit back on...hold buttons for roughly 3 seconds....Let me know if it works.
