check your speakers and speaker wires for shorts and/or grounds. If they check out fine try pressing the reset switch.

My kenwood kdc-mp53u flashes PROTECT whats wrong with it?


Protect indicates that there is a short or a grounding problem usually within the speakers2_bing.gif or the speaker wiring. Locate and press the reset button (pinhole). If protect comes back then disconnect all speakers, reset and connect them back one at a time until protect shows up again. This will help you find out where the unwanted DC signal is coming from. If protect shows up when all speakers are disconnected, then it may need service.

try either pushing the reset switch or disconnect power to the radio. if that does not work, check your speaker wires and speakers for shorts, and make sure your speakers are not bad. if all this fails, you probably have a bad output ic.

On my kenwood kdc mp438u i tried everything it said to do but it keep saying protect


Could be a short circuit on your speaker output, try disconnecting all 4 speaker wires and then power up. Otherwise its the audio amplifier circuit that needs to be replaced ( audio IC )

Same problem protect keeps flashing


kenwood has an internal protection feature that stops the output of the speaker channels if there is a shorted wire or bad speaker. this happens for many reasons and is not always serious problem. you can reset the unit by pushing the reset button with the tip of a pin while the until is on. it is a very small black circle located somewhere on the front of the faceplate. it should go back to normal operation after rebooting. if the protect comes back, you need to take it to your nearst shop to have them troubleshoot your speakers and connection.

hope this helps

I got a Kenwood KDC-MP438U and its stuck on protected mode


Protected mode means that there is a speaker wire that is grounding out on the chassis, another wire or another wire. Check all the wire connections to make sure there is no loose wire that may be getting grounded out. After it's insulated properly and reconnected, hit the reset and you'll be back in business. k

"PROTECT" is constantly displayed on the screen of my kdc-mp438u


You need to unplug the unit from the back and find the problem. Usually, it is almost always your speaker connections. Once you find the problem within the speakers, plug it back in and it resets it.
