Question about Audio Players & Recorders

1 Answer

Denon AVR-1707 hooked up to 2 main speakers with fuse intact and unit shuts down after protect relay kicks in. Red blinking light on power button and shuts down in a few seconds. When a lightbulb is placed where the main ac fuse is, the unit powers on ok and does not shut down. Sound from both speakers or headphones fine. There is a slight very low hum but unit does not shut down.

Hi.

The main AC fuse amp is insufficient, or there is an abnormal power draw caused by a contact (often caused by speakers).

The fuse must be at least 22 amps, please check it out.

When I power my Denon AVR-3311ci on, it only comes on for a second then shuts off completely. No blinking red light and nothing on the display. I can hear a relay on the power board clicking. Any ideas?...


There's an electrical problem! The unit shuts off to protect itself. the relay sound is normal and is part of the power supply - good quality amps have them. I suggest taking it to your local repair shop.

Red power light blinking on my denon avr 1907, tried reset procedure, no speakers hooked up now and it still goes from green light to blinking red light and shuts off...Any clues?


This is a protection mode. The receiver protection circuit detects an internal problem like missing power supply voltage or blown channel and shuts down the receiver. You need to bring the unit to a repair facility.

Trying to hook my lg tv to a denon avr-1707 receiver so i can have external speakers


Use the twin phono audio out on tv to twin phono audio in on Denon AVR-1707 this should work absolutely fine as long as your using an analogue input on the tv if HDMI you would need to purchase a Digitial to analogue audio converter. Hope this helps

Protection error in denon avr-3000


Hi,

Do you know what caused the protection shut down in the first place? Did you short your speaker wires even briefly?

You could try to Unplug the Unit for Few Minutes, say 30 minutes and then turn it back ON.Usually that would fix the issue.

If you are going into protect mode with no speaker attached,chances are that your output Ic is in need of replacement .This is the most likely cause of a protection error that you are experiencing.I am having a bit of difficulty in locating specific part numbers but feel confident that replacing outputs will remedy your concern.For further info and parts or authorized service locations in your area I suggest to contact mfg at www.usa.denon.com/ .Click on support or call(201)762-6500.I believe that they have a flat rate service and will give you an estimate.

Still, on the remote possibility that it is just a glitch caused by momentary power interruption or fluctuation, try to re-initialize the microprocessor, a hard reset (not unless this is what you were referring to as rebooted). The reset should force the AVR-3300 to revert back to factory defaults removing glitches, errors in settings & configurations, memory & presets as well as user preferences.

* turn OFF the unit using the POWER button;
* press and hold both SPEAKER A and SPEAKER B;
* without releasing the 2 buttons, press the POWER button;
* release the 2 buttons only when the display starts to flash;
* in the event of no display flashing, repeat the process.


Should the above be not corrective, then it would be a hardware fault and not just a glitch.


Let me know, if needed further assistance.

Hoe i helped you.

Thanks for using ' Fixya ' and have a nice day!!

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.

Denon avr-2106 getting hot shutting down


Normally when this happens it is because the impedence load is too small. This unit requires 8 Ohm speakers. If you connect 4 Ohm speakers, it will work, but work harder and generate excessive heat. If the heat is too much, the unit will enter protect mode and shut down. Once it cools off, it will work again. In your case, if the speakers are the correct impedence, check for crossed wires. If that is the problem, running the unit at higher volume levels should cause it to shutdown sooner.

Keep us posted,
Dan

Denon AVR 886 only shows analog input


Are your speakers able to handle the 886's power. I have the same reciever and changed by speakers as the Denon would turn off instead of frying the speakers.

As for the digital, have you used the option to change your audio feed and video feed. (for example - I'll show photos through the front input but use the CD -digital for music. Maybe the audio feed is locked onto an analog input. Just a suggestion.

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.

No sound or display but power


You may have toasted the amp. You cab try reseting the microprocessor by using the hard power button and the a b speaker buttons. turn the unit off using the power button. hold the a and b speaker buttons and while holding turn the unit back on. screen should flash a couple times. release a and b buttons. good luck
