SOURCE: Powers turns on then off

See: http://www.denon.ca/hapdfs/avr2105mane.pdf, 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.

I have repaired many of these Denon receivers over the last few years.

Since the headphones work, that means if you dis-connect the speakers it will turn on and not go into protect (when power cuts off a few seconds after turning the unit on).

The most likely problem is a bad speaker. to find out which speaker is causing the problem, do this.

Start out with just one speaker connected and then turn on the unit. If it turns on and plays music, you know that speaker is good.
Now turn the unit off again and add another speaker and keep the first speaker connected. Once again, if the unit plays, that speaker is also good.

Keep doing this same procedure one speaker at a time. As soon as you connect a speaker and then try to turn on the unit and it goes into protect, the speaker you just connected is bad.

To confirm that this speaker is the bad speaker, dis-connect all speakers and only plug the suspected bad speaker into a speaker jack that worked with one of the other speakers.
If the unit still goes into protect you know then that you have found the bad speaker.

If the unit still goes into protect, that speaker is bad and you will need to take it in for repair or replace it.
make sure you use 8 ohm speakers. if i remember correctly these Denons can use 6 ohm speakers, but those are harder to find and most home speakers are 8 ohms.

If the unit does not go into protect and that suspected bad speaker plays in one of the other speaker jacks, what you really have is a bad channel in the amplifier, the channel that the suspected bad speaker was previously connected to.

If you find out you have a bad channel, you will need to take it in to an repair center. Preferably an authorized Denon service center. There are not very many of those around. I work at the only authorized Denon service center in the entire state of Michigan.

If I can be of more assistance, don't hesitate to ask. And a good rating is always appreciated. :)

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!

SOURCE: shuts off then red light indicator flashes, disconnected all speakers but still wont work

Hi, this is a power board issue. remove the cover and make sure that this unit doesn't have blow fuse. if the fuse is fine, you will then need to replace the integrated power/ main board.

SOURCE: Denon avr-1804 its turns back after 5 sec

Disconnect all speaker wires on back and then turn on. If it happens again, it's most likely a power supply problem. If it doesn't happen again, it was probably crossed speaker wires.

Denon 1909 flashing red ring after 20 minutes


Well on most models red ring singals :

1 ) speaker wires touching something they should not
2 ) internal overheating, shutting down to protect
3 ) something is wrong, bring in for service.

I'm guessing it's out of warranty?

Denon avr-1506 will turn on then flash red and turn off... how do i make it stop or fix it??


In most AV receivers if the standby light flashes after turning on and you don't hear the regular click of the relay engaging after 4 seconds, indicates an output short or amplifier failure. The protection circuit prevents any further damage by not turning on system.
You will need professional help to fix this problem because even to a electronic enthusiast the construction of a typical AVR is not service friendly.

Power button turns green, flashes and then turns red and flashes.


Hi,
While working it stops and flashes red approximately 2 seconds interval

Causes
Protection circuit is activated depending on the temperature of the surroundings

Remedy
Switch off the power supply and power on after the temperature have reduced.


While working it stops and flashes red approximately 0.5 seconds interval

Causes
1.Using speakers having less impedance than the specified.
2.If speaker core wire touch each other Protection circuit is activated


Even applying power red flashes 0.5 seconds interval

Cause
Amplifier circuit has failed

Remedy
Switch off the power and contact denon service centre


Thank You

I have a Denon AVR 1509 and when I turn the power on it flashed green but after about 2 seconds it cuts out and and then flashed red every 0.5 seconds.


Usually its the power output stage . You can visibly check it if theres a burned resistor on the output amplifier. On the base of the Power output transistor if the voltage is the same as the collector pin it will indicate a shorted power amplifier circuit.

Denon avr-2106 problem!!!


You're drawing too much power from it. Sounds like maybe your sub is hooked up wrong, double check that.
