    I have a Kenwood KDC-W3537A and keep getting the flashing 'PROTECT' msg. I have tried looking to see if any wires are showing, insulating them, reset button, disconnecting and reconnecting battery and fuse, and plugged it in without the speaker dock bit connected but still get the PROTECT msg appearing. I bought it second hand and the wires the person sent with it seem a little worn in places but I have covered them etc, and was told it worked fine but would this have anything to do with it, or if the PROTECT msg is coming up when the speakers aren't connected does this mean there is a fault with the actual player itself? I hope you can help.

If the reset button doesnt work you can pull out the entire stereo and locate the fuse on the back, simply pull it out and put it back in.. that resets it also but it's what i have to do everytime i get the protect on the screen

I had this problem with the set I bought and tried the resets etc. The protect would flash up later and sometimes would not reset (intermitant fault) as I had been told the problem was with the out put for the speakers we disconnected the wires and protect went off (after reset) it was then trial and error connecting the speakers one by one (had to bypass the block for this) until we found the speaker that was causing the protect display. we then chased a wire through the car to replace the original. PROBLEM SOLVED. I believe a wire had frayed somewhere and was earthing on the bodywork, hope this helps.

The protect message means that a problem was detected and that the output speaker connections have been disabled. Please verify the exact model number and I should be able to provide more details on the likely defective parts.

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.

KDC-MP2032. Why is PROTECT being displayed?

Look to the right of the SRC button in the corner, and you'll see a small button that you can press with a pen tip or paper clip. This is the reset button, and pressing it will turn off the protect mode. If it keeps coming back, there may be a wiring problem, or the head unit may be defective.

En estos modelos quedan grabados los errores de DC en el eeprom y se tiene que limpiar y estos son los pasos para este modelo:

Mientras que el display muestre PROTECT presiona el y sosten el 3 y 6 y luego presiona el RESET mantelos presionados por unos dos o tres segundos y luego suelta el RESET y despues de uno o dos segundos suelta los otros switches.
El display debe mostrar:

Presiona el 1 y el display mostrara

Presiona el 1 y sostenlo por par de segundos y el display mostrara

Presiona el 2 y el display mostrara
DC2 4

Presiona el 2 y sostenlo por un par de segundos y el display mostrara
DC2 0

A este punto el eeprom ya esta limpio y nada mas presiona el RESET y el disply debe mostrar STANDBY

Espero que esta informacion te sea util y avisa si te funiona

Suerte y saludos

My JVC car stereo display " Protect " on display



1 Answer

My car stereo flashes the word "PROTECT"

If this happened while playing music at a little higher volume, you must check the speakers for short in coils. disconnect the speakers to see if the protect condition changes, if so check the speakers and wiring. If not then you must have blown up the output IC or a power shorting within the set. You will have to remove the pcb disconnect the power to the output IC to confirm the fault. Helpful I hope. Good day

I have a Kenwood KDC-MP442U Deck and protect will not come off

check speakers for a short protect means one of the speakers are shorting so check all the connections on speakers or if you have a multimeter put the black to ground and put it on contanuity and check from the plug at the unit and it will beep if one is shorting then you know which one to check instead of pulling your whole car apart:)

On display is says "protect" what does that mean?

Try disconnecting the power supply to the back of the mp232 then reconnecting it. This worked for me AFTER doublechecking all of my speaker connections.

"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.

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).
