Or you can jus hold the reset button with the radio on until it says standby then try turning the unit on, or jus reenter the code on the unit which is 3214 and try step 1 again

You have a shorted speaker wire or a blown speaker. The unit is protecting itself from damage. Did you install it? if so, pull the deck and check your connections. If they all seem fine, disconnect one speaker at a time, and turn on the radio. Make sure the radio speaker wires are taped so they don't short and cause more damage. Test each speaker wire until you find which one is causing the problem. Now re-connect all the other speakers and test. Next, disconnect the speaker wire right at the speaker that's giving you a problem, tape it off, then re connect it to the receiver. now test again. If all is ok, you have a bad speaker, if not run a test wire from the radio to the possible bad speaker and test again. If the speaker plays, you know what the problem is, replace the bad wire. Most often it's a door speaker wire or a wire got pinched during installation and took a while to short. Hope this helps

SOURCE: 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.

SOURCE: 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,

Kenwood cd player keeps flashing "protect" when i turn it on. How do i fix this?


The "Protect" message indicates that the unit has detected a short or surge in the wiring to the unit. Check your ground and make sure that the speaker wires are not the problem. (Any broken wires or speaker wires that touch the case of the CD player could cause the issue.)

If there are no obvious wiring problems, then the unit has an internal short. That should be resolved by sending the unit for service if it is under warranty.

Please add a comment with the model number of the CD player for additional information. I hope this helps.

"Protect" isn't for security on a Kenwood; it's caused by a problem with the speaker output. There may be a defect in the CD player, or you may have a blown speaker or a shorted speaker wire in the vehicle. Try disconnecting all the speakers and see if the unit still shows "protect" when you turn it on. If it still shows the "protect" message with no speakers connected, the unit needs to be serviced; if not, re-connect the speakers one at a time until you find out which one is causing the problem.
