SOURCE: power to stereo none to unit

There is a ribbon cable that goes from the display to the main board of the radio that may be bad, if you have everything connected properly and all you get is the red led, this is a possibility. No way for anybody to know if you have it wired wrong if they can not look at it themself.

The red wire is for power when the key is on, the yellow wire should get power all the time, the black wire is ground.

If you have those correct, the radio should at least turn on. If you have these right, you may need a new ribbon cable. The connector that interfaces with the detachable face must also be taken off the old ribbon cable and put on the new one, or get a new connector and just replace it. The ribbon cable does not come with that connector. It is soldered on the ribbon cable, so if you are not very good with a soldering iron, you should have a service center do it for you.

Let me know if you want the part number for the ribbon cable and/or connector, I can get those for you.

I can not guarantee that the ribbon cable is the problem, or that it is the only problem, but it is the most likely problem with that model number of Kenwood. I have repaired many of them, so I have a good idea what causes most of the problems, but I have seen times when the usual suspect is not the problem and something else like the LCD in the face is bad, or the IC that controls the display is bad. Even a voltage regulator on the main board of the radio can be at fault as well. There are probably about 10 different things that can cause that one problem, having an experienced technician is always the best way to determan the problem with certainty.

Let me know if I can be any more help for you.

SOURCE: face plate wont turn on

On the faceplate back, there should be some metal contacts. Take a white (not pink, red, purple, etc) pencil eraser and clean the contacts on the faceplate back. You can take a little rubbing alcohol and a q-tip to the contacts on the player itself...just use a little bit. Let it dry for about 5 minutes and try again. If it has a reset button, you may try pushing it, however that will most likely reset the clock, radio stations, and any eq settings.

There is no display on the faceplate. The faceplate is stuck in the CD eject position. If I remove the faceplate the mechanism rotates to the position where the controls would be visible but when I attach...


I would try cleaning the connectors on the face plate with an pencil eraser and on the unit itself with a very fine sand paper. And make sure you get rid of any dust after cleaning before putting the face plate back on.
Please leave me a good feedback.
Thanks

Control head will not power up. I put power to the unit and hear the cd player movement working inside but no control head activity


make sure the face plate is in correctly. This unit has a removable face plate and it could be half way in. Also, check to make sure the little copper contacts are clean.

The car security is not connected to a head unit. It probably has a small blinking red light on it which blinks when you remove the faceplate and switch the ignition off. This is just an indicator which lets people see that the face plate is removed.

You can replace the headunit with any brand/model you want. It would be cheaper than buying a replacement faceplate.
