Kenwood KDC-MP235 CD player flashes Protect

push reset pin on front of face with a pin while vehicle is on.

check all of your speakers and speaker wires for shorts, grounds or bare wires.

its when it has had a surge back from the speakers when i had this it killed the head unit but just try plugging the power side in only

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

Protect:- The speaker wire has a short circuit, or touches the chassis of the vehicle, then the Protect function is activated. Wire or insulate the cable properly and then press the reset button. If the "Protect" code does not disappear, consult your nearest service centre.

take a pen and press the reset button ...it's a tiny little button next to the button that takes off the faceplate...

"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.
