The system go to protect mode in case of trouble in output stage(power output component and cords and speakers.
try to connect each speaker one by one until you find the bad one change cord first for the bad one and check if not working you must change speaker itself.if all above does not solve the problem you must pass your sony to service center

Jl 1000/1 goes into protective mode with low frequency

Do you have a capacitor????? If not, when its up loud and hitting hard it might be going into protection because of a voltage sag....If it goes below 11.8v they will usually do that.....Get a multi meter and put on the hot and ground of your amp when its playing loud and see what the voltage is dropping to.....If its going below 12v, thats your luck....

When volume goes high, the system goes in protection and relay's clik is heared

This is not the fault with remote control. Check the load connected to the device. If overload occurs, the device will itself go to protect mode. Disconnect speakers one by one and check which speaker box causes the system to go to protect mode, when volume is incresed. Check that speaker for short.

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,,

Pioneer VSX-D209 receiver shuts off when too loud

Dear Tabasco,

Your receiver is basically going into protect mode.

Just 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 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!

Stereo goes into protect mode

Protect is a safety feature so that you do not blow your speakers. However with it hooked up with the computer you may have surpassed the max output. If it still does this with out going through the computer, it has been damaged.

The unit may be experiencing an overload caused by a short circuit, internally or externally. Try disconnecting all the speakers, then turning up the volume. If nothing happens, connect one speaker at a time and turn up the volume to see if you get more sound. You may have a speaker that has shorted internally and this will help you discover the bad one. However, if when you have all the speakers disconnected, and the unit still goes into protection mode with the volume up, then there is a problem with the unit itself.

Hope this helps, and please rate my advice, good OR bad.

Good luck!
