No reset will help this. The problem is an internal short most likely in in one of the amp circuits. This is a relatively simple repair for a service shop. Expect a parts cost in the $40 range. Add in the local labor rate for the total repair cost.

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.

Sony DE-445 reciever flashes PROTECT


Sounds like a grounding problem. If the ground plug isn't missing or loose try plugging it into a different outlet.

A common cause are failures in the amplifier output stage, the drivers, and some of the support components. You will have to send the unit out for service.

HI, I have a sony v555es amp and it gives me the following error message "protector OPT.....please power off"


You might be trying to push it too hard, or you might have a short somewhere. Disconnect everything from the reciever except its power cord and turn it on. If it still goes into protect mode, then try to find a reset switch (not sure if this is on the Sony, some recievers have them). If it's NOT in protect mode, then you had a speaker wire shorting out on the back. Make sure that you don't have any stray wires when you connect the cables on the back of your receiver. It only takes one strand of copper to short out the amp section. If that doesn't work then pull the top cover off and chech the fuses out. One of them might be blown.

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

Stuck in protect mode


Speakers shorted out, blew a fuse. Replace the unit or (cross your fingers and) open up the box and find the blown fuse.

Make sure that you are not asking too much from your system by having a "heavy" bass contour, or processing externally that amounts to the same thing...accordianman
