My denon died three times with the same fault.
Playing music at moderately high volumes then the amp would shut down and never start again, just displayed the red flashing power light.
First time was with 5.1 engaged and playing music, second time with only 2 speakers connected, also playing music.
Speakers are aaron AST4's at 160w with 93db sensitivity.
First time the amp was "repaired" under warranty then a short time later it blew again (still under warranty) exactly the same problem.
This was then "fixed" again. Soon after the alleged "repairs" and just out of warranty the amp blew again.
The denon Australia service dept now refused to fix it out of warranty and I'm out of pocket $1200 (original price) and was told I need to pay for the same recurring problem to be fixed.
What would you do if this had happened to you?
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!
I have had this same problem. What is going on? Mine has blown twice, now out of waranty. What am I going to do?
I will never buy Denon again. ****!
I took mine to a local authorized Denon repair depot and they 'rebuilt' my amplifier for around US$185. Works great...just going to keep from playing the music loud for extended periods going forward.

Hi Mainard, mine WAS taken to a local authorised denon repairer (3 times) and "rebuilt"twice LOL
The main problem I'm having is that the receiver fails at moderately high volume levels (key word being moderately) and the last two times it failed the unit had only just been been switched on.
As you may or may not know those 93bd speakers are highly sensitive, hence very easy to drive and should not present any problems at all what so ever to the receiver (especially one touted at having such high current capabilities.)
Electronics can and do unexpectedly break.
The real problem lies with the denon support/repair centre.
One would expect after paying over a thousand dollars to get treated a little better than this.
One would also expect not to have to bear the cost of a obviously faulty from the factory unit.
Paying to have the unit "repaired" a third time would be idiotic. I would not feel comfortable having it fixed then selling it knowing full well it would in all likelihood blow up again.
The bottom line is don't gamble with your money and buy a denon.
Easiest response is "ditto". The receiver has been replaced three times. It sat in a box while I was building a new house for a year and a half. I set it back up about three months ago. The unit now turns on by itself a few times a week, and two weeks ago the "t.v" input died, but only on zone two. The local dealer does not sell Denon anymore because of the many issues, including the ones listed plus bad power supplies. Not only has Denon lost a good customer, but you can guarantee everyone I know will also know to stay away from Denon. Another quality company bites the dust!
