    Denon AVR 1906 As soon as unit is turned on it shuts off. 1 1/2 yrs. old. Was doing nothing when it began, just turned unit on. I do not play it loudly. After it did this several times there was a wisp or small puff of smoke that came thru the top. Can't find anyone locally to work on this brand.

    Denon AVR 1906 stopped working, it was being played pretty loud and is was extremely hot. Power light comes on but will not fire up to the main power transformer. Have tried resetting using both speaker a b and powering up, but still nothing more than the power light from around the power button. Any advise helpful. Thanks

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!

Units dc protect mode is probably activating due to Blown channel (shorted output transistors) I work for a Denon Authorized repair Center in Michigan If shipping to Michigan is economical let me know kstahl65@att.net

Denon avr-1706 turns on, but then after start up goes immediately off. I also had similar problems with volume turned up too loud turning off the entire unit. What can be done?


Continuously stressing it with loud volume has succeeded in making an intermittent problem int a solid one.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on; or it may turn on but produce no audio to the speakers.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.

Whenever I start playing on my xbox or playstation, the receiver will shut off (the red light is blinking around the power button). Once I hit the button, it stops and then I can turn the receiver back...


does it only shut off on high volume or a loud noise?

It's the amp tripping to protect itself.

look out for a shorting speaker wire or faulty speaker etc. disconnect each in turn to find out which

Denon AVR-4802R automatically shuts off in multi-zone mode


i had the volume of the multi-zone tuned too high and was attenuating it in an external control box. Once i took the multi-zone volume down to -25db, the problem went way. My main zone was operating around -35db so did not have the problem.

Denon AVR-1906 Reciever is not working. Was watching a movie and then it suddenly shut off. Now, the power light is blinking red. When I try to power it on again it starts to boot up but then turns off...


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.

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.
