It is possible that you have a failure in the powerr section/ power audio output of the set that is protecting the set from furrther damage. First of all disconnect the speakers and check if the protect changes. If so your speakers are shorted, take a test and confirm.If not you will have to take out the set and open to probe into the main board. I would advice this only is you are familiar to do such work or else take help to investigate into the board for possible shorting of the output, the possible failure of mechanism drives, motors or power regulators. The set has to be powered to take the voltage test, disconnect the efffected or faulty section for the protect error statement to change. Now you can replace this component. Hope you fine this adive helpful Good day

    Helpful..My receiver is a Kenwood KDC-MP 242..Im not sure if receiver will continue to operate or shut down to "protect" itself again..but by removing the fuze to the 12v power supply for a few seconds, my unit started working properly again... minus program needs like clock and station presets..as i would expect with a power failure..thanks for steering me in the right direction... steve

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.

Kenwood kdc-mp345u keeps flashing protect, and i've disconnected the speakers and unplugged the radio for about 30 min, plugged radio back in still flashing protect


Chances are pretty good either the output ic or the volume control ic inside of the radio are bad. Both require the ability to use a soldering iron to replace.

Protect code


make sure you have no bare or shorted speaker wires and check your speakers to make sure they are all good. if that all checks out, you probably have a bad output ic.

Security Code for Protect mode


Turn on the car so the radio is flashing "Protect." Look on the front / removable face of the stereo. On it you will find a small round hole - that's a reset button. Find a small paper clip, unfold the clip and stick it gently into the hole. The "Protect" will stop flashing, and Kenwood will be displayed. Unfortunately all your settings/presets will be gone, but at least the stereo is working again!
