Re: My Denon AVR-887 Keeps turning itself off

The Unit turns OFF it self after 10-30 sec.
- Detach 5pin cable which going from AMP Bar Code to HDMi PCB (Board)
-Turn ON the power of unit
If Unit will power UP and doesn't turn OFF.
More chance malfunction HDMi board but for sure
have to test triodes of AMP Bar Code assy.

Re: My Denon AVR-887 Keeps turning itself off

I have one and the same thing happened. try resetting your microprocessor and if that does not work, then check the wiring of the speakers. if that is working fine and no wires are touching then I unplugged everything and was still having the issue. took it in for service and it was found that the transmitor was shorted as the speakers that I was using was too high in ohms. it is possible that it could be your caps also if resetting the microprocessor does not help. You can find out how to reset the microprocessor from your manual. If you have the Denon avr 887 with the system turned off hold the power on button and the speaker A and B at the same time for a few seconds. This is compatible to rebooting your computer. Hope this works for you as this was and is my husbands favorite past times.

Denon avr-887 code for comcast silver remote, red key. The 2 codes comcast gives me do not work. Any other codes known?

These are the codes that I have from a few extra sources. They are for ALL Denon receivers/tuners: (3 digit = 262,307)For the AVR all numbers consisting of a 4 number code, all begin with a "5". Here they are: 5006, 5048,5054,5085,5129, 5130, 5131, 5132, 5133, 5134, 5152, 5159, 5160, 5168.I was able to get my 529 rc to program some of the features but I will go back and try other codes that may have a better "fit" and operate more features. Hope this helps!

Where is the fuse in a denon AVR-887

It has to have one---follow the power cord inside the unit--if fuse is good consider taking it to a shop for an estimate.

It turns on flashes green then turns off

Missing some cable connection between
boards. Check cable.
If all cable intact connected try-unplugging cable one by one then power ON. Plug back unplug other one. Start from cable, which attached to HDMi board.

My Denon AVR 3806 keeps turning itself off, why?

Your receiver has short circuit somewhere. The protection circuit shut off the unit to prevent more damage. You can try to disconnect all speakers. If there is not improvement, you need to send your receiver to repair.

Denon AVR-887 turns itself off in 5 secs, any one know why?

You might have the polarities on the speakers crossed, check all speaker connections to make sure the pos and neg are connected correctly. If they are crossed, this will cause the receiver to short out, thanks

Denon AVR 887 Upconversion With Wii

I have this hookup and it's working almost perfectly:

Wii --component--> Avr-887 --HDMI--> Sharp LCD TV

Sometimes the pictures don't show up during start up, but I figured it was (probably) due to Sharp's HDMI handshake issue, so I turned the TV off and then on, everything works.

Denon AVR-887 and Wii

I'm dealing with the very same frustration. Best I can tell, the problem with my setup is that this model (avr-887) can't pass component video input out through HDMI. Can anyone confirm that? 
Prior to setting up the Wii, I'd only been using a single HDMI output from the denon to my tv/monitor.
The only solution I've found is to add a component video output to the monitor -- which is unfortunate. I'd much rather have only the single HDMI out.
Would love to hear if there is a way to set this up without having to add the additional component output...

Avr-2802 constantly restarting itself and flickering on and off

check all speaker wires from the receiver end and the speaker ends. Just the smallest strand of copper could be touching something it should not be touching. Make sure all copper is in the speaker post and not hanging out. The receiver is getting a short and shutting off to protect it self. This could have happened since you were just plugging things in.
