    When I turn on the unit, it starts up but then turns itself off after about five seconds. I have tried to reset the microprocessor as directed in the owner's manual but that has not helped. Any help would be greatly appreciated!

    I have a Denon AVR 2106 and it has the same issue. I tried to reset the microprocessor according to the owners manual to no avail. The amp will power on, but it will shut off within approx 3-4 secs.

    We have the same problem! We thought our DVD player burned it out, because it was plugged into the Reciever itself, but now I am not so sure since there is the same problem happening to lots of other people.

See:, page 72. In my case, the problem was a connector between my receiver and television. I unplugged it from my receiver and it now works.

Denon AVR 2105 5years old has worked perfectly. Now all of a suddend Zone 2 does not come on. Any ideas why after working perfect for so long?

Bad button on the remote? or
static discharge from being touched can cause all kinds of strange problems.
I would reset the micro processor back to default settings..
AVR-2105 or AVR-885 Front Speaker A and B (2 keys)
Let the front panel blink 3 or 4 times and then release the keys (buttons)
You will have to do your set up again i.e. speaker size, assign inputs, FM presets etc.

Maybe. Clearly something blew up. Diagnostic time costs money. Then there are parts and labor.

You can get a new one on ebay ending tomorrow for as little as $140 delivered.

Denon AVR 2105 power shuts off, tried resetting the micro processor and no luck. Please help...

The receiver has an internal problem like bad power supply or burnt channel. You need to bring it to a local repair shop or mail it here.

Denon avr 2105 died (3 times) dead AVR2105 faulty avr-2105

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!

Power wont stay on

Hope your under warranty mate and if so hope its not in Australia as they cannot fix this problem. My denon was allegedly fixed twice but has now failed a third time (just out of warranty) and denon have turned their back on me.
