Same Problem

-   My Denon AVR-1600 amp simply shut off last night.  Came back on for awhile then quit again.  Power light still on.  Any ideas?  Should I fix or trash?-   wetztv

-   I forgot why i put the receiver in the closet: its "power off" mood swings.  I've noticed that when the stand-by light is flashing, it's in one of it's moods.  Once light stops flashing, e.g. three days later, the receiver will work... for awhile. -   lalala848

-   Power on ... charging condensators ... after very short delay:enters std.by-mode with blinking LED.
Prior to the issue; Exposed to some heavy use in a 5.1 speaker configuration, though working after this.
B-Speakers also connected though not engaged while incident occurred.

Schematic for this with measurepoints and reference voltages -anyone?-   Norsch

There is a problem with one or both of the audio amp circuits. The amp is going into a protect mode as to protect and save your speakers. Sorry but there is no simple fix. this will need to go to the shop to be diagnoised. Good Luck
