Question about Denon Audio & Video Receivers

1 Answer

I have a Denon AVR 887 surround sound receiver head unit in my living room. Today I was putting in new speakers, and it worked fine for about5 minutes, then it shut off. Now I keep getting a red flashing light when I try to turn it on.

If your amp looks like it's going to work as normal (ie the front display lights up as it should etc), but then the amp goes into protection mode when the anti-thud circuit times out, then I know what's likely to be wrong.

It's one of the power amplifier channels which has gone faulty.

I just found this out after having this problem with my AVR-1906.

I took the amp apart and de-soldered the suspected channel power transistors (centre channel in my case).....and hey-presto! it fired up as normal (obviously the centre channel would be out of service).

I have ordered the replacement transistors from Farnell (UK) at a miserly cost of around £2-£3 each.

Just waiting for them to arrive.

An alternative is, if you don't use all your channels, take the transistors from a known working but not needed channel and swap them over with the duff ones.

Hope thats of use!

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.

Surround sound not working


Bad DSP board (digital signal processing board)- a common problem for Denon receivers. Hope you have a warranty.

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

Speaker connection from Denon AVR 2105 to Wharfedale suround


The spkrs sound like they are bi-amp spkrs, meaning you have multiple terminals on the backs of each spkr, the jumpers on the spkrs should be connected as such. Now you just connect the spkrs according to the Denon spkr conection diagram. Do not use the surround back unless you have 6 or 7 pair of spkrs

Denon AVR-1403 connected to DVD can hear music but no dialougue!!


Check the center channel speaker and the surround sound audio settings. If you do not have a center speaker, it needs to be set to off on the receiver.

Denon AVR 883 Audio glitch


More than likely the protector circuit is getting activated... You can't go below 6 ohms on the surround back which means you need 12 ohm or higher speakers for outside (since the two outputs for surround back/zone2 are in parallel). As a simple diagnostic test, disconnect one speaker and see if the sound survives longer than 2 seconds.

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.
