Why is it showing "protect" ?

Hi,

Please shutdown your device, remove all the wires connected to the sony device and then turn the device back on again. Watch to see if the issue occurs again. And if not, please add all of your wires back. Thank you.

It depends on what happened to the receiver. Have you tried to connect up the unit to the wall socket yet, without the Monster power strip? If that does not help you, and the unit still gets pops and goes into protect mode, you have an issue with one of the output stages in the amp. I'm afraid that this type of repair can only be diagnosed by a tech who knows how to trouble shoot solid state amplifiers. You may also contact Monster cable, as if you can get the tech to agree with you on the cause of the problem, most of the Monster Cable power strips come with a warranty against this problem from happening and will pay for the repair. Good Luck

Have you solved ???? Thanks .. I have the same problem

Try combination of SURROUND+EXIT+CLEAR to reset

Do you hear the speaker protection relay click after about 10 seconds when you turn the receiver on? Does the display show PROTECTION on the display? These conditions indicate a bad channel that will keep the receiver from functioning but you still have lights. Steve

You must be having a power Amp output problem. There must be a short circuit in one of the amplifiers and that is triggering the protection mode to prevent speaker damage. You will need professional help for this since the circuit is complicated and so is the construction. Getting access to the under side of the circuit board for removal and replacement of the components is very difficult on all modern AV receivers.

Hello,there is a chance that you have a damaged speaker and that the amp is ok. Check the unit with no speakers at all connected,if there is no overload displayed then its a bad speaker.

If protect is coming up on the display, it means the system is detecting a short somewhere on one of the speakers and so is turning the amp off to avoid damage.
Check all the connections at the back of the amp to ensure they are not shorting, and at the back of each speaker, if nothing is found there, check each wire for damage, or a bare wire touching the body of the car

Disconnect all the speaker wires at the receiver and turn it back on. If itdoesn't go into protect mode, your receiver is ok.

Reconnect the speakers one at a time being sure to turn the receiver off each time you connect a speaker and turn the receiver on until your receiver goes into protection mode again.

When it goes into protect mode again, the last speaker you connected has a problem. Trace the speaker's wire to the speaker looking for cuts or shorts along the way.

If you have a multimeter, switch itto ohms and check the speaker for a dead short, if you show a dead short you have a blownspeaker. Hope this helps.

Protect is an indication that one of the output amplifiers is shorted. The unit turns itself off to avoid burning more components. I'd recommend taking it in to a repair facility for replacement of the blown output amp.
