Question about Pioneer DEH-P645 CD Changer

1 Answer

I have a pioneer KEH-P4100RDS head unit which the display has gone dim on ( seemed to half go out then a day or so later go fully out ), everything else works so was wondering if it is possible to replace the display bulbs/led's and where to get them from or could it be another problem ?

Another issue with detachable face units is the spring on the latch gets weak over time and the contacts will not be 100% reliable. Try cleaning the contacts between the unit and the faceplate and also make sure there is not debris in any of the latching mechanisms that could be causing the face to not sit totally flush on the receiver. By the way, cassette tapes...really?

The LCD display is failing, or the driver ic is the issue, or the B+ is to low causing the dimming effect, a resistor gone high in value would explain this.

Keh pioneer will not illuminate


I am assuming you are talking about the tape deck (head unit) and not the changer. You more than likely have burned out bulbs in the face. Unless you are good at desoldering and soldering, I would suggest you have them replaced professionally.

Depends on the type of car you have. Do you have a harness or are you going to splice all the wires? Does your car have a premium sound system? Are you going to run an amplifier now or later on in the future??
