There is likely a problem in the power amp section that only becomes apparent when the increased volume demands sufficient current in that stage to push the amp into a potential component failure situation. The protect circuit clicks in and disconnects the speakers from the amp to protect them from damage should the power amp stage experience a catastrophic failure. Unless you are a trained technician, you should have the unit repaired before major damage occurs.

I have this issue, my teac ag d7900 which itself off to standby and when I switch it "on" again, it says protect and shut itself down again


Right. This means that either you have a short in your speaker cable somewhere or the short-detector circuitry inside has problems. Disconnect all speaker cables and turn the receiver on. If the symptom goes away, turn the receiver off again and connect one of the speaker wires. Repeat until it starts to go into protect again. When it does, the last speaker you hooked up has a short somewhere in the wire.
If protect always comes on, you'll need to get the unit serviced.

My stereo sysytem is a mini stereo: serial number 10200055. It currently says "protect", what is this and how do we return our system to normal operations?


Hi there,

When the word PROTECT appears on this display, this means the unit has detected a critical fault which could potentially cause harm to your stereo system.

The most common cause is a short circuit somewhere - something even as simple as loose speaker wiring could cause a short, triggering the Protect message.

You will need to determine if there is a possible short somewhere, so I recommend you start by firstly turning power OFF, disconnecting all speaker wires, then turn unit back ON.

Operate the stereo (without speakers) and turn volume up:
  • If Protect message appears when turning volume up, then stereo unit itself has an internal fault
  • If no Protect message appears, then suspect the speakers may be causing the issue.
  • Reduce volume and turn unit OFF
Re-connect speakers (ensure the connections are secure), turn unit ON:
  • If turning volume up triggers the Protect message again, there is an issue with the speakers or connections

Hope this helps.....

My yamaha rxv595a keeps on shutting itself off when im watching movies as soon that it gets loud it shuts off but its not even that loud how do i fix this problem i tried the ohms switch in the back and it...


That is a safety switch in most receivers. When something gets too loud it cannot give the load off to the speakers and shuts off to protect itself. This can mean that the receivers getting old, or that you might need to split the job. You might need an stereo amplifier to split the job. Check the cables and speakers. Recievers can only give so much to so many speakers at so much sound. That is what the whatts are for. The more whatts the better, the lesser whatts, the lesser speakers its going to be able to handle at high volumes.

When playing dvd or or on video 3 playing a directv movie. Receiver keeps shutting off and the screen says protect. Seems to do it when the movie scene gets loud.


check your wires if there not touching behind the speakers and receiver. when it says protect this means something is shorting out or crossing over. one other thing it may be is if a speaker is starting to go bad. (please rate)

Whenever I start playing on my xbox or playstation, the receiver will shut off (the red light is blinking around the power button). Once I hit the button, it stops and then I can turn the receiver back...

It's the amp tripping to protect itself.

look out for a shorting speaker wire or faulty speaker etc. disconnect each in turn to find out which

I have a Denon DRA 697C1 receiver,and my speakers are 300 Watts, when I give volume to the receiver, it get hot and shut off, How can I solve this problem?


Which speakers do you have? The Denon is best for 6-8 ohm speakers. If your currently hooking them up to speakers that are 4-6 ohms, it will shut off to protect itself. The other thing to check is the wiring. What guage are you using?

My Onkyo tx-sr606 7.1 receiver turns off by itself


hi, when the unit shuts off by itself, it means that the protection circuity inside has been activated. it can be a problem with the receiver itself or it is just detecting something hooked up to it that can cause possible damage so it shuts off.

you would need to disconnect everything from the back and by itself, try to turn it on, see if it will stay on and then crank the volume way up to max. if it stays on, the receiver is ok and you then need to rehook your devices one by one starting with the speakers until you determine the one causing the receiver to shut off.

however, if the receiver shuts off and won't turn on even by itself, it means that the problem is internal and it either has to go back to your dealer for an exchange or it has to be sent to a repair center for servicing.

hope this helps a bit.. ^_^

My system shot down during a movie


The reason why your receiver is going in protect is because there is a short circuit happening. This would either be on your speaker wires, speakers or receiver itself. What you want to do to check would be:
1. Unhook all sources and speakers from your receiver.
2. Turn on your receiver and crank up the volume to maximum, if your receiver does not shutdown or go on protect then the receiver is OK. If it does shutdown and go on protect then its an internal problem on the receiver and you would need to send that over to an authorized service center.
3. Hook up a source and 1 speaker. Play something from the source or the fm tuner, Crank Up the volume to about 46 or 47 volume. If the receiver does not shutdown, its good.
4. Hook up a second speaker and repeat the process until you encounter the pop and shut down
if for example you encounter the pop on the 4th speaker, try changing the speaker wires.
5. If the receiver still shuts down then it would be a short on the speaker itself and it would need to go to an authorized service center.
