First of all remove speaker wires from deck in off position,then put the set on and see if it goes in protection or not. If not then check short circuit for speaker wires.Or else put headphones and see if sound comes,if it doesn't then go to service centre if you are not an engineer.All the best.

Protect

This is caused by a short in the audio output ic, first check the speaker wiring on the back for shorts, if okay! it is the above mentioned part that must be replaced.

HI ....MY COMPUTER SHOWS A WHITE SCREEN (this computer system.JXJG9H1_595B, is protected by a password authentication system. you cannot acess the data on thi computer without the correct password .please...

Your computers boot up has password protection enabled or you hard drive has been encrypted for security.
This is very difficult to fix as it's meant to protect your personal information in the event your PC is stolen or lost.

I was accidently connected the subwoofer ,when my sony hi-fi volume level is 30 (maximum)...and then it automatically shutdown..after that,it started to show PUSH POWER ,PROTECT..

Hi, I believe the sub is the wrong kind for your system. It should be a selfpowered sub one that you plug in to AC power and then connect to Hi/fi. You could do some damage to your system if you carry on with that. Good luck

MY KENWOOD CAR CD PLAYER IS SAYING PROTECT??

Hi,

Kenwood head units show "protect" when there's a problem with the speaker outputs. This might mean a shorted speaker wire, a blown speaker, or an internal defect in the head unit. Once the condition that's causing the "protect" mode is fixed, the CD player should be back in normal mode the next time you turn it on.

If it's staying in "protect", then you'll definitely have to remove the stereo and do some troubleshooting to fix it. Many car audio stores will do system troubleshooting, for a fee. If you want to do it yourself, here's what you need to do:

Pull the Kenwood unit from the dash and disconnect all the speaker wires. Turn it on and see if the "protect" message displays. If it does, the stereo has an internal defect and will need to be serviced. If it doesn't, then turn it off, and re-connect one speaker. Turn it on again and see if it displays "protect".

If it works with a single speaker connected, keep re-connecting the others until you identify the speaker that's causing the problem. There may be a wiring problem or defective speaker in that location.

If it displays "protect" with a single speaker connected, then disconnect that one and try a different one. If all the speakers cause a "protect" mode, then you're probably back to a defective head unit, unless your friend managed to blow all your speakers at once.

Thanks,
