Unfortunately you can not just turn it off. Protection means that a problem was detected in the final output stage and that stage was shut down to prevent further damage to either the amp or the speakers. The typical problem is either the output transistors on one channel or the output amp chip for one of the surround channels. Expect a parts cost of about $25-$40 plus hte local labor rate for repair.

AVR X1000 going in protect mode?


If you used it for only 3-4 hours before the problem occurred then you should have a replacement warranty on the product.
I think you have already done the factory reset procedure shown on page 175 of the user manual.
Is it possible to take it to the place you purchased it from. Alternatively check the Denon website and find out who the closest agent is in your locality. Send it back with proof of purchase using a courier service that you can track for receipt. Hope it turns out well.

Denon avr2312ci shuts off and blinks red


Yes that is why. The receiver is protecting itself from an un-stable load impedance which causes current/voltage spikes through the final amplifier components and proportionally through the input where the protection relay is (click),. Do not continue using the amp until you have repaired or replaced the blown speakers. A rule of thumb is to maintain 8 ohms on each speaker wire plugged into the amp. Keep that in mind or eventually you will damage it.

How to take protect off a denon receaver


Hello. DC Protection is not something you can turn off. It is a protection system engaged by one of the microprocessors (computers) within your receiver. If any of the amplifiers are bad, and producing DC voltage at the output, the micro will immediately turn the unit off, to lesson further damage to the amplifier or speaker system. There can be other causes of why the unit's DC Protection relay is not engaging, but 90% of the issues, are related to amplifier damage.

Power button turns green, flashes and then turns red and flashes.


Hi,
While working it stops and flashes red approximately 2 seconds interval

Causes
Protection circuit is activated depending on the temperature of the surroundings

Remedy
Switch off the power supply and power on after the temperature have reduced.


While working it stops and flashes red approximately 0.5 seconds interval

Causes
1.Using speakers having less impedance than the specified.
2.If speaker core wire touch each other Protection circuit is activated


Even applying power red flashes 0.5 seconds interval

Cause
Amplifier circuit has failed

Remedy
Switch off the power and contact denon service centre


Thank You

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!!

Standby light on and system not working


OK either a channel has blown or it has the Denon Curse. At the factory, denon installed some surge protecting resistors in the power supply. They are a little too small and well after warranty expires, one day, while playing music, or just turning it on, the resistors open up and the unit stays in protection mode. Denons were FAMOUS (or infanous) for this problem. I have repaired DOZENS of them. Take it to a denon repair shop as I GUARANTEE they have seen this before. Don't try ro repair this yourself as to get at the 4 resistors you have to disassemble the ENTIRE unit. Good luck....Rob

Stuck on standby


Unit is in protect mode there are a few problems that can trigger protect mode the most common is blown channel (shorted outputs). Sometimes one of the 15v regulators may go bad causing imbalance of supplys triggering protect mode. Also sometimes a bad solder connection could cause unit to go into protect also. I work for Denon authorzied repair center in Michigan if your nearby and Shipping to Michigan is economical let me know kstahl65@att.net
