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.

SOURCE: Denon AV Receiver Model AVR3600 locked at'' Protection '' mode

The problem with this receiver is NOT the power supply, but the output stage of the amplifier section. The most common failure is shorted output transistors. There are problem detection circuits that will shutdown the receiver and display the "protect" message when a problem is detected. This is to prevent further damage to the receiver and speakers. The typical parts cost for this repair uis between $20- $40.

SOURCE: How do i reset my Denon udra m1o tuner amp from

Protect mode can not be "reset". This mode means that a problem was detected in the final amp stage and the unit has been shutdown to prevent further damage. The most common cause of this is failed output transistors. Plan on a parts cost in the $20-$20 range for this repair.

One or more channels have a short in the audio output stage causing the protect mode to engage " saving it from further damage " this will require a professional or Denon service. I'am not aware if there are issues with this model.

My denon avr1200 receiver once it is turned on goes into Protection mode. How do you reset or make work?


The reciever will go into protection mode when there is a short in the speaker wires or the amplifier was overloaded. What I would do first is verify that none of the speaker wire connections are loose at the back of the reciever or at each speaker. And verify that none of the wires are making contact with each other. Then label each speaker wire as you remove them from the reciever so you can re-install them correctly. After you have disconnected the speaker wires try unplugging the reciever for 10 to 15 minutes. Most recievers have a self-resetting overload protection switch and this should reset it back to normal. Now try plugging the reciever back in and turn it on without the speaker wires connected. It should be out of protection mode now. If it is still in protection mode verify that there is not a reset switch somewhere on the back of the reciever. If it is not in protection mode now then proceed to connect one speaker set at a time and turn on the reciever to see if it goes into protection mode. If it goes into that mode after connecting a speaker then that speaker is the cause of the problem. If it does not go into the mode after all speakers are connected then try turning the volume up. If it goes into protection mode then there could be an internal short on the amplifier or a incorrect OHM rated speakers connected to reciever. Verify that the speakers are rated the correct OHMS.

most of the receivers come with a cooling fan inside see if its working they usually work when you turn the volume up,, if its working that means you are playing it to loud if you lower the volume a little it will play just fine..( if the fan inside is not working thats the reason it goes into protect mode and it means you must have it repaired,, it goes into protect mode to prevent furter damage to the unit or the speakers,,

My aplifier Denon UDRA F-10 says "protect"


Blingking Light or Protect usually means that there is DC appearing in output stage and is protecting Connected Speakers.
It can be faulty Output Stage (Bad ICs/Transistors/Resistors/Capacitors) or Faulty Power Supply.

Working on These types of Problem is not user friendly at all.

Advising to take local Authorized Shop.

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?

The receiver has gone into a protect mode because something is wrong and it shuts down to prevent further damage. Could be a power supply or output amp issue.
