SOURCE: Denon AVR-810 going into PROTECTION mode

It sounds like there is a problem with the differential circuit. The bias I am not sure about, as every unit is different. You should get the service manual to be sure or call Denon and see if they can give you an idea. Good Luck

SOURCE: Denon AVR older receiver but worked fine; now

Did you try to reset the unit? Resetting the unit has fixed every problem I have ever had......turn off unit.....hold down A+B at the same time then turn the unit back on...hold buttons for roughly 3 seconds....Let me know if it works.

SOURCE: HK AVR-247 protect mode

This is an indication of an internal problem. Typically this is shorted output transistors. Expect a parts cost in the $25-$40 range for this repair.

Denon avr 1700 hp/only. how do I turn headphones off only?? I reset but did no work. can I clear the memory by unplug power, fuses ect??


try plugging in headphones and unplugging them. the headphone jacks have a tendency to have a shorted contact in them that cause the unit to think there are headphone plugged in all the time. Only true fix is to replace the headphone jack, but pluggin and unplugging can temporarily clean the fault usually.

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.

Denon AVR-1100 receiver "PROTECT" mode


replace all the electrolytic capacitors in the power supply. i had the exact same problem with mine and once i replaced the capacitors it powered up and stayed on and worked perfect.
these capacitors tend to fail as they're of poor quality.
this fault is very common on denon receivers, especially the later models.

hope this helps?

Amp comes on and goes right into protection mode I turn on my Denon stereo receiver AVR-1500 an it goes to protection mode? Can someone please help me?


Do you still have the AVR1500? I have one with a bad tuner--and would be interested in purchasing your for parts. Let me know if you still have it and if you'd be willing to sell it.

Turns off after 4 secs or so....From Green to Red,


probably one of the surround channels is blown, thats why it goes into protection, meassure output transistors with a ohm/diode meter if thers no shortcut in the base to collector

Going into protect due to either blown channel or probably a 15v regulator might be down which I have seen many times also. causing unit to go into protect.

Turns it self off with a sparking noise in the speakers


The unit has a built in protection mode if a fault occurs in the speaker wiring. If its in protection mode the power button light will flash and display goes blank. Try disconnecting all speakers and see if it stays on, if so it could be a shorted speaker wire or bad speaker.
