Amplifier Protection Mode Troubleshooting - Car Audio Help

One of the more confusing car stereo problems can be when an amplifier goes into protection mode. One minute it's working and the next minute it's not, ...

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.

Maybe there's a correlation to those devices being attached. Float the the amp so it has no cables to anything and figure out why it's going into protect mode. If it doesn't, start adding units until it does.

THIS IS NOT A MODIFACTION ,ITS AND ADDITION TO THE ORGINAL SERVICE MANUAL WHERE THEY LEFT OUT THESE PARTS ON THE ORGINAL SERVICE MANUAL.

The protection modes in these units ****. Most new units have them. What I do is turn down settings on deck and turn up amp as much as possible. Then the protection won't turn on because you won't have to turn it up as high.

I discovered that there is a compatiblilty problem between the Bose receiver and the Sony amplifier. If I disconnect the receiver from the amp then the amp starts up normally. Apparently the receiver sends out a dc offset or a "thump" that the amplifier doesn't like and goes into protection mode. I solved the problem by putting a 1 second delay circuit between the receiver startup and the amplifier startup. A simple RC delay on the remote input to the amplifier solved the problem.

Your receiver is basically going into protect mode.

The SR 605 contains a microcomputer for signal processing and control functions. In an unlikely event, it may cause it to lock up. Unplug the power cord from the wall outlet, wait for 10 to15 seconds and then plug it back again.

Please also check your speaker cabling again. Make sure that all of them are seated properly, none is touching each other or the body of receiver. Take out all the wire and put them back again if necessary..
Some times even a little tiny frayed wire touching the receiver could trigger the protect mode. Be careful, since protect mode is sometimes not fast enough and it could blown a few trasistors in the power circuit.
Just check your speaker as well....whether they play all right thru another receiver or amplifier. its posiible they might be shorting inside. A little frayed wire could also trigger the protect circuit in your receiver.
I hope this should solve your problem. If you still can’t resolve the issue yourself, try resetting
the AV receiver/AV amplifier before going on to opening the Receiver.
To reset the Receiver to its factory defaults, turn it on and, while holding the [VCR/DVR] button, press the [STANDBY/ON] button. "Clear" will appear on the display and the Receiver will enter Standby mode. (note that resetting your receiver will delete your custom settings as well as your radio presets).

If everything else seems all right and still your receiver shut down when you raise the volume then it possible that there are bad connections on the main board that are set in.

This would generally happen if the system is slighly old or have dry solder and when you raise up the volume. This should be a simple repair that will not require parts. If you can solder, you will be able to repair this yourself. If not, then a local service center will change the local labor rate.

Hope you can sort out your problem with the above trouble shooting. Let me know if I can guide you further.
Best of luck. Thanks for using FixYa!

you have to verify your connection cause if you are a short circuit in your different output or input the protection mode is on. it's an internal security
first disconnect all your output speakers, and restart your amplifier if the protection mode is on again try to disconnect all your input device and restart your amplifier, the protection mode should be off, so after connect one device after one to check who makes your protection mode on
