Speaker terminal are short circuit,switch power off connect speaker properly then switch power back.
-the ventilation holes of the set are blocked-turn power off and make good ventilation around leave the set to cool and turn power back.
-the unit is operating at continuous high power turn it of and allow for cool down and switch it back.

Red power light blinking on my denon avr 1907, tried reset procedure, no speakers hooked up now and it still goes from green light to blinking red light and shuts off...Any clues?


This is a protection mode. The receiver protection circuit detects an internal problem like missing power supply voltage or blown channel and shuts down the receiver. You need to bring the unit to a repair facility.

I was watching a movie on my denon avr-3808ci and all of a sudden it made a loud sound and it shut off. The power button was flashing red and wne I tried to turn it on, the power button would turn green...


probably one of your speakers has blown.. disconnect them all. turn the reciever on.
if this works turn it off connect one speaker and turn it on.. keep going until it goes red...
when you find the speaker discennect all the other speakers keep this one connected and confirm that it is this speaker giving issues.

if the amp doesn't come on with all speakers disconnected, remove the visual outs and start it with nothing connected. isolate the issue if this works. otherwise it might be your amp.

When i power up the reciever and watch tv the reciever turns off and the power button blinks red. I unpluged the reciever for 1 hour and put it back on. nothing changed. i even unpluged the speaker wires...


You have an internal short in your receiver could be power supply or most likely a output transister. There is a code to the blinking red light check your manual it may list the number of blinks with problem. However its not a simple fix. plus make sure HDMI cable is unplugged when reseting receiver if this cable has a short it may cause it to. Sorry to hear the bad news, nice receiver
GOOD LUCK....

I have a Denon receiver, had it for a couple years now and has worked perfectly. Last week I was watching a movie and all of a sudden my receiver shut off and it blinked a red ring of death. I let it rest...


Did you recently move any speakers around or any items near the speaker wire connections?
It sounds like you may have a speaker wire shorting which is causing the receiver to go into "auto protect" mode. Check all of the speaker wire connections on the back of the receiver and at all of the speakers to make sure the wires are not touching or close enough to possibly touch.

Shuts off then red light indicator flashes, disconnected all speakers but still wont work


Hi, this is a power board issue. remove the cover and make sure that this unit doesn't have blow fuse. if the fuse is fine, you will then need to replace the integrated power/ main board.

Denon AVR-1100 receiver "PROTECT" mode


replace all the electrolytic capacitors in the power supply. i had the exact same problem with mine and once i replaced the capacitors it powered up and stayed on and worked perfect.
these capacitors tend to fail as they're of poor quality.
this fault is very common on denon receivers, especially the later models.

hope this helps?
