SOURCE: Denon AVR-1907 blinking red power button

It sounds like you have a bad speaker on the zone 2, or you have the speakers connected improperly.

When you engage the zone 2 a relay clicks and the speakers then become part of the amplifiers circuit.

If the problem was in the amplifier, it would go into protect mode without even having speakers connected to it.

If the speakers all check good, you most likely have the wrong type of speakers, meaning the impeadance is too low, or you have too many speakers connected to it.

On the back of the Denon, you will see right around the speaker output jacks, what ratings the speakers should be. If I remember correctly, it says 6 ohms or more when using only "A" or "B", and it says 12ohms or more for "A" + "B".

If you have two 8 ohm speakers on the same speaker jack you now have a 4 ohm load. That is below the ratings and can cause the amp to shut down (go into protect). Since your amp shuts down right away, I think you have a bad speaker or way too many speakers connected.

I have seen many times when people will connect 2 or 4 speakers to the one of the outputs that are designed for only 1 speakers.

If you are using too many speakers you will need a speaker distribution box. It has a resistor network built into it so the amp never sees a lower impeadance than what it is designed for.
You can connect 4, 6 or 8 speakers to one set of outputs designed for 2 speakers. You do loose a lot of power to the speakers, but it is better than blowing up your amplifier.

If I can be of any further help, let me know.

SOURCE: denon avr-2106 problem!!!

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

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.

Why denon avr-1712 blinking red after shut off


Does it attempt to power up or just sit there blinking at you.?

No power output or display.green standby light flashes.


Sounds like either a blown mainpower fuse or the thermal fuse for the power transformer. If the protect circuit was kicking in, the display would light up, but then turn off with a red blinking light. the green light with no display means the transformer is not getting power.

Denon AVR-1908 won't power on


Are you getting a standby light at all? Is it flashing? Do you here a click when you plug the unit in? If the answer is no to all of these then you blew a fuse. If you do have soome sort of standby light, then your set is in protect mode. More than likely for a blown channel. If no lights, but you ar egetting a click, you could have a bad transformer. Use a DVM and see if it is open or not. Good luck

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.

When I turn on my receiver, it automatically turns off and the power button flashes red. Prior to shut down, the receiver display notes "Tuner Ext. In" What's the problem? It has worked p


Protection circuit turns off the unit because of critical conditions- wrong power supply voltages or one of the power amplifier channels is bad. First, visual inspect the power amp board near the heat sink for burned resistors, test outputs for a short. If there are no problem you may try to turn the unit on and you have several second before it shuts down to check power supply voltages and power amp output voltages and bias, then ... Long story you'd better take it to a repair shop or repair at ebcelectronics.com

Shuts off after only a couple of sec.


Your reviever is "clipping". You need electronics service from a professional repair shop.

If you are savy in the world of electronics... Most likely you have a bad cap or preamp circuits that are overdriving the amp supply.

Power Button Flashing Red


Try unplugging the entire unit and letting it sit for 5 minutes. See if this helps. If not, you need to do a complete reboot, which will cause you to lose your settings, but will probably solve your problem. To do a complete reboot, you will need to hold down two of the front bottons on the front panel. I'm not sure which, so either consult your manual or see other posts here which describe the reboot process for Denons. Hope this helps.

Power Button Flashing Red


Check to make sure the +/- speaker output wires aren't touching. I've had this problem before with frayed speaker wire strands poking out & intermittently shorting to the other polarity speaker output. This amazing receiver actually continued to play at low volume levels, but if I turned it up it would shut down similar to how you are reporting. I cleaned up the frayed wires & this fixed thr problem. Good luck
