    every thing unpluged from back except power, still shuts off

  • Anonymous May 21, 2009

    I had my Denon less than 1 year. It did the same thing. Denon fixed it saying the amps filters were weak, yes weak! I added cooling fans the **** out excess heat, so my filters stay strong not weak. But I have a 1969 Sansui with less power and gee the filters are original! Todays gear is just over-priced ****.

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.

I have the same problem.. I have a sony blu ray hooked up to my denon receiver and it keeps shutting off after about 2 minutes of play. Extremely frustrating. This is the second Denon I have owned an I'm not pleased with either one. Not worth the money.

AFTER 2-3 SEC THE AMPLIFIER SHUTS DOWN AND THE ON/OFF BUTTON FLASHED RED sOME ADVICE?


Check to make sure the speaker wiring is secure, failing that! the audio output stage that drives the speakers is the problem, you probably have a short and the safety shutdown circuits have be activated to prevent further damage. It will need a technician to remedy the situation.

Might be over heating. Make sure you don't have anything sitting directly on top of it. I even put a little fan blowing outward at the back of my system to keep it cool.

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.

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

Receiver shuts off when trying to play a dvd in the dvd player.


Just a hunch - what's drawing power from the two convenience outlets on the back of the receiver. They're only rated for 120watts, that is, nothing like a TV.

I doubt this has anything to do with the source you're playing (unless you have it cranked to "11"). If I understand you correctly you said turning the TV on and off causes the problem. There's a clue.

Standby light stays red and will not turn unit on.


Try to reset the macroprocessor. Unplug the unit from AC, hold both buttons SPEAKER A and SPEAKER B and plug the cord in outlet. After display flashes several times release the buttons. No result? - repair shop.

I have a wireless headphones the only number i can see is model f0461b on the trasmitter. The transmitter and headphone are not comunicating the lights are red not blue.How do i recalibrate them so they...


In rare cases, the FreePulse Headphones may loose synchronization with the receiver. If this occurs the following steps will re-establish the connection by putting both the headphones and the receiver in discoverable mode (actively searching for another bluetooth device it can connect to).
Putting the headphones in discoverable mode:
Press and hold the power button (located next to the charging port on the right earpiece) on the headphones. The LED on the button will go through three states in this order:
  • Blinking Red
  • Off (continue to hold. the LED will be off for several seconds)
  • Alternately blinking red and blue. (The headphones are now in discoverable mode and you can release the button at this point. The headphones will remain in this state for 30 seconds).
Putting the receiver in discoverable mode:
Press and hold the power button (located on the side of the receiver opposite the headphone jack).The LED on the button will go through three states in this order:
  • Blinking Red
  • Off (continue to hold. the LED will be off for several seconds)
  • Alternately blinking red and blue. (The reciever is now in discoverable mode and you can release the button at this point. The reciever will remain in this state for 30 seconds).
Re-establishing the connection:
To re-establish the connection between the headphones and the reciever, put the headphones and the receiver in discoverable mode at the same time. It will take a few seconds for the two devices to establish the connection. Once the connection has been established the LEDs on both the headphones and receiver will glow solid blue.
