Re: Main Display Window

Hello Gully, the flat cable between the front panel and the radio. If you want I can give you the part number but the replacement of this cable is not simple. Best regards, Arpi

Hi there,

I also created a tutorial on fixing faceplates with 2R7 resistors (refer to my tip).

But, your unit will have a different chassis, as the faceplate is also a video display.

First you need to determine if the buttons on the faceplate are operating the various functions. If the buttons are NOT operating, then the faceplate itself (or connection to the main unit) can be considered faulty.

It's highly probable that the RIBBON cable (which connects faceplate to the inside of the unit) may be defective - this is common in some Kenwood units.

Try searching Google or youtube for ribbon cable repairs etc.

Hope this leads you in the right direction.

Kenwood KDC-MP428 - the display is out but works otherwise

there are several surface mount resistors on the right side inside of the deck that need to be resoldered.

Operation buttons and sub display are failing

go to ebay and type in the model number of the unit and it will bring up some part that can fix the problem. i had the same problem and i just ordered the part. its actually a ribbon connector. im sure you just open up the radio and take the old one out and connect the new one up. this seems to be a common problem with this unit. the ribbon just starts to tear, and as it tears, you will start to lose functions on the stereo. i happen to like this stereo, so i decided to repair it. good luck with yours.

I have a CDX-M8815X unit only works with remote commander

The problem is the ribbon cable,the one connects the face to the main board,if you live in USA you can order it from or
For replace it you will need to open the unit and open the face by moving manually the gears,then remove the side screws of the face and remove face,then remove the cd mech. you will see the ribbon connector.Just replaced and put everthing back togheter.
Good luck

No display but fully functional regarding sound

More then likely the flex cable that connects main p.c.b to the connector keyboard plugs into is defective. For service manual email

Main lcd not working.

If the unit is a flip face then suspect the ribbon cable to the main circuit board from the front display. If it isn't a flip face then suspect that the back light lamps are out. If you can see a very very very dim image of the display when it is running then for sure it is a back light problem.

Face Plate

If this is a "flip face" type of display then you may have a broken lead in the ribbon cable that connects to the main board from the flip face. This is a very common problem. You'll need to replace that ribbon cable.
