Hello
problems with Avr units are the internal supply always fail with in time.
mostly -15v and +15v are the regulators 7815 and 7915.
the mpu takes care of the AVR .. the control unit stops the AVR not to get more damage ,
if you now or have the knowledge about Electronics, check power supply voltages, regulators, check capacitors.
dont forget to check soldering points also.

Good luck
Happy to help

Hi...
That sounds like a amplifier module /section that has failed.
Do you ever get power surges at your place?

Wont turn on it stays on stand by


This could be a power supply issue to a audio output problem, I strongly recommend a top notch tech to check your unit because this is a high end device.

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.

Denon AVR-1604 too large front speakers blew the avr


Try disconnecting the speakers at the receiver. turn it on radio or any other source and turn up the volume. If the receiver still shuts of, there is an internal capacitor issue and needs serviced. More than likely though, it's a speaker problem. If the speakers were underpowered and at max volume, chances are the damage was to a voice coil in one of the speakers. If the receiver continues to stay on without being connected it's ok. check your speaker wires as well. Frequently loose braids on wires touch each other and create very little resistance until turned up, more volume, more resistance. Then the receiver puts itself into protection mode so no damage will occur. If you need further help, post a comment and I can help you troubleshoot further.

Won't stay on


This is normally caused when the overload protection circuit kicks in. To see if this is the case, unplug everything (except power) including speakers and then power on th receiver. If it stays on then try reconnecting speakers one by one. If one of the speakers causes the failure then follow the speaker wire back to the speaker and examine for damage. If all speakers work then start adding components back one by one and test as each one is re-connected.

good luck

Reciever Powers Down


Hi...
Check ALL your speaker connections at both ends.
What kind of volume are you running it at and what kind of airflow do you have around it>?
Thanks

Wont stay on.


The only way you can fix this is you have the proper tools and have very good soldering skills. If so, I will post more instructions on how to fix this.

It has a blown channel, it can not be fixed without some good troubleshooting skills. The protect mode is so you don't cause more damage to it. If you continue to turn it on, you may cause more damage.

Your best bet is to take it in to get repaired at a service center.

Let me know if you require more help,

Dave

Receiver shuts down and will not turn back on untill you unplug and plug back in


Nope. sorry to burst your bubble but your problem is pretty common on this unit. Its bad capacitors in the power supply and probably not worth repairing in a repair shop. since this is a solid state reciver, there are no user replaceable parts inside.
