The red ring on the power button on my DENON AVR 1706 is flashing continuously, not sure what it means, after my niece turned it on, it turned off and started flashing. What's wrong with it, does anyone know?

Hi, this flashing means that the device has a short circuit in any of speakers connections or it's overheated, in the first case check if the speakers wiring has no bare wires touching each other, in the second case check that the ventilation holes of device are not covered or blocked with something.

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.

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!

My denon avr-1706 is going into protection mode immediately after turning on. whats the problem?


You either have an overloaded output or a shorted powersupply. If you have verified that your connections are not the cause then the problem is internal and will require service from a trained technician. Switching power supplies are notorious for going bad. Two of the main components are the FETs used for switching and the PWM generator.

Denon avr-1706 receiver just shuts off


This sounds like the amps protector circuit has been activated due to thermal overload. switch it off for an hour or more to let it cool down, make sure your spkrs are connected properly, don't parallel. Try using a fan on the unit to get that heat away. Get a techie friend to give the insides a once over, and clear away any dust that has built up.

hope this is of some help,
Cheers Kimbo.

1706 Red ring of death


Check all your speaker connections to make sure none have shorted out.
It appears the protector circuit is being activated upon startup. cut the power altogether to the unit before checking it.

Power button (light) blinks


Check your speaker cables, make sure none have shorted out. if they have, then thats why the unit won't power up. The units protector circuit is being activated upon startup.

I mwas gonna suggest that you need the speakers attached but you stated later that it did the same thing with the speakers attached. The unit switching off after it checks its self is NOT a normal thing. TAKE IT BACK BEFORE ITS TOO LATE!! GOOD lUCK
