SOURCE: Protect mode

You may have loosened a solder joint on one of the components inside with your air blast. A repair tech would monitor the outputs DC offset voltage and he will probably see one that is not zero volts and while wiggling various things he should see a sudden change in the DC offset voltage on the bad channel when he touches the bad connection. Then it's just a matter of resoldering the connection. Good luck on this one.

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.

Getting out of protect mode I have a Denon 787 receiver. It was working fine for 8 months. All of sudden, my reciever goes into protect mode after playing for about 30 min. Right after it goes into protect...


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,,

Protect displaying


Protect on any reciever usually means that it has reached its maximum capacity of volume (known as clipping) and at the reciever is now automatically reducing the volume to avoid damage. This some times is triggered if the reciever was used hard and is now damaged so you would need to bring it to a repair shop. Sometimes its caused by a bad wire to the speakers, a short to say. Check all your wiring, make sure its not overheating and getting plenty of air. Some where its recieving a signal telling it to go into protect mode.

Amp comes on and goes right into protection mode


Turn the reciever on for a second or two and then off before the protect mode shows up on the monitor. Repeat this step about five times and check to see if the reciever does not go into protect mode. If it does go into protect mode try it again. Dont know if this is the proper way to fix the reciever but it worked for me. Good Luck
