The unit is telling you it's shut off output because of some problem. There night be something wrong with one of your speakers or the wiring. A speaker may have shorted or a wire may be contacting a sharp edge somewhere and shorting to the car frame. This could also be due to a problem in the amplifier itself. Try unplugging the speaker wiring from the unit and see if it clears up. If so you can start isolating which speaker or wire run is bad. If the unit is still in protect without the load, you'll need to have it serviced.

My cd player is just showing PROTECT and not working??any ideas please


I would need more information such as the manufacturer and model number, I assume it's a DAF 44 but who makes that? In GENERAL
If PROTECT or PROTECTOR is flashing in the display of an audio device such as an A/V receiver, or home theater system (hts), there may be an external speaker issue or connection issue that is triggering the protection circuit

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,

Display read protected and wont do anything


Usually, protect mode is enabled when the speaker output wiring has shorted together or is touching ground/+12V. I would verify that none of the speaker wiring has come loose.

My audio system says protect on display


Hi Jean,

Without a brand and a model, best that I can provide are generic possibilities:
1. unplug the unit from the mains for a couple of hours. This is supposedly to reset most systems; and/or
2. check the speaker wires and make sure none of any bare wires are touching each other.

If your concern has not been corrected after completion of the above procedures, pls post back brand and model.

Hope this be of initial help/idea. Pls post back as requested, how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Kenwood in dash cd player


The protection function is activated when the speaker wire has a short-circuit or touches the chassis of the vehicle. Wire or insulate the speaker cable properly and press the reset button. (The reset button is that little pinhole button below and to the right of the volume control). If you do this and the "PROTECT" code doesn't disappear, you'll have to consult a service center. Further, if you had this professionally installed, they should be obligated to fix the issue for you (hopefully).
