It goes into protect mode then shuts off. its not the fuse and i have unpluged all speakers and it still goes to protect mode then shuts off.

From what I have seen..........

Either you have a speaker that is shorting out, Try unplugging on speaker at a time and turning the unit on, and see if it goes out of protected mode. Keep the volume turned low while doing that. Just go by process of elimination. Or you can disconnect all speakers and see if you still get the error message. If not then connect 1 speaker at a time, if it goes in to protected mode while doing a speaker connection then you found the bad speaker.

Otherwise another thing I read a hard reset you should be able to do on the unit is hold down the power button until it display a message that says "Clear All", then hit enter or follow the directions it gives that should reset the alarm code if the receiver will allow it.

Hopefully one of those 2 things will clear your error........

Best I could find out

I would do the speaker test first, usually its a shorted speaker or wire

Disconnect all speakers Meter power, remote, ground at amp, if all is good move on, if not check main fuses
Turn amp on; If in protect mode then your amp is toast Turn amp on, if not in protect mode then start reconnecting speakers one by one until your amp goes into protect mode, then you'll know which speaker is bad.

Hi:
First disconnect all speakers from the unit and then try turning the unit on too see if it still goes to protect mode. Protect mode is a shut down feature that shuts down the unit because of a shorted speaker or speaker wires are touching each other. If the unit does not shut down after disconnecting all speakers then reconnect them one at a time while turing the unit on after each conncection until you find the shorted speaker. If it shuts down with no speakers attached to it then you have a internal problem with the amplifier section, probably a shorted output transistor in the Amp circuit or preamp circuit.

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.

POWER IT UP WITH NO SPEAKERS CONNECTED AND NO RCA INPUTS. IF IT STILL GOES INTO PROTECTION, THEN IT WILL NEED SERVICE. WHAT YOU PROBABLY HEARD AT FIRST WAS THE OUTPUT TRANSISTORS SHORTING AND STARTING TO SEND DC OUT TO THE SPEAKERS WHICH WOULD DESTROY THEM AND FURTHER DAMAGE THE AMPLIFER, SO THE PROTECTION CIRCUITS SEE THIS AND SHUT THE AMPLIFIER DOWN. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE....V

If this happens only when connecting the receiver, chech the receiver cable. If the cable is fine, receiver connector at the back of receiver is faulty.

Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Regards.

protection mode activated to protect from serious damage and please follow me.1-shut down your system2-make volume in low position3-remove all your connected speaker4-switch your system on and watch if it does not go to protect mode insert your speaker one by one until you find the bad one and change it and start with cable change first and then speaker itself-if it goes to protect mode you must call service center.

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

i have a jvc stero and every time that i turn it on ...it show protect and shuts off!
