KDC-X869 Face Flips Halfway, Unit Turns Off

My Kenwood unit about six months ago started having a problem. When the ignition is turned on, the unit will open halfway (flip to a 90 degree angle straight out), then turn off. I can push the power again, it will flip open about 10 more degrees then turn off again. It will keep doing this until I am able to turn it on and keep it at about a 100 degree angle (slightly lower than halfway flipped down). Only then will it stay on. I do this every time the vehicle is used.

Is this a problem with the ribbon? or possibly a short in the connections? I've repaired computers and cars, but never stereo units so its a bit foreign to me.

Thanks for any help.

    I just replaced the flexible ribbon cable that goes from the keypad to the LCD Display (part J84-0154-015) as that's what most said is probably the problem, but the issue is still there.

    here's a video I did from my phone of the issue in action:



    When I turn the car on, the unit flips open halfway then powers off (while staying open). Then I press the power button, and it opens a bit more and powers off. I do this a few times while it cycles through opening all the way, closing, then opening again. Sometimes if I hold the keypad firmly while it's opening on the last "leg" before closing again, it will stay on. Any ideas?

    Cancel that, I figured out the problem. The plastic lever for the angle recogniser switch had worn down to a nub (the part that slides against the gear). Since I wanted a quick fix, I cut a small piece of plastic cable tie and super glued it to the end of the nub, then filed down the edges and made it perfectly sized. Lastly a quick gearing alignment and it's all better, haha.

I have worked on many of these radios and there is a lever that contacts switch to determine position of face this lever wears out and switch does not operate properly causing radio to lose its mind. This is usually the cause of this failure unless flip gears have been damged somehow. contact kstahl65@att.net for additional info

Kdc-x969, when the unit is tured on the face does not flip down. most buttons turn the unit off but the face flips down instead of up when it shuts off


It very well could be that the internal motor that moves the faceplate is going out or has already gone out. It sounds to me like that could be the problem.

it's a Canadian Kenwood.

I had the 925 purchased from Ebay, but I sold the car with it.
it's probably the ribbon wire broken between the face and the unit. I know that on Ebay some they use to offer a repair for these type of units.

My Kenwood KDC-7024 has just started playing up - as soon as you turn on the ignition, the face panel comes down, flicks on for all of 2 - 3 seconds and then closes, it then keeps doing this repeatedly...


It's possible the flexible PCB (more of a cable, really) that connects the faceplate to the main unit has cracks in the conductors. This has been an issue with some of the older Kenwood HUs that have the MASK motorized faceplate. The flex-cable gets bent and pinched enough over the years that it eventually cracks the copper.

Alot, of the radios have a common problem with the connection from the radio's detachable face. What happens is corrosion builds up on the connectors between the pin and the connector itself. Sometimes you can clean it off with a small file. Also, some KENWOODS with the motorized face are known to have a problem with the ribbon cable connecting the face plate to the main board. The last time I repaired one I called KENWOOD and aquired the cable for about 65 dollars, what the problem is, is the cable is wrapped around a plastic white spindel with a high tension spring and places alot of pressure on the cable from the wear and tear of the face opening and it will cause strange problems such as: turning on and off, some buttons working while others don't, and the display partially turning on and off.

it needs a new ribbon cable. Some car audio repair shops stock these (mine does). Part is about $20-30. Labor will depend on the shop.

Kenwood KDC-MP825 car stereo problem


My wife experienced the same problem this month, December 2008, after owning the KDC-MP825 for 3.5 years (what's up with that?). It would power on briefly, the panel would move, then after 2 seconds it would shut down. After 15 seconds, it would power again, panel motors whir, then shut down. It would keep doing that while the key is in ignition.

This appeared to have solved the problem:
Hold down BUTTON [5], press the RESET button (you'll need a ballpen to press between the AUTO and SCRL button).

This was the procedure for getting the receiver out of demonstration mode. Maybe the cold weather here in New Jersey placed the unit into demo mode?

Kenwood KDC-715s problem.


the kenwoods with the motorized face platesdevelop one problem with time. the flexable ribbon cable between the main unit & the face plate. as the face open & closes, over time wares out the cable. problem consists of face plate not opening/closing, display missing & and/or some or all buttons not working. note these can also be intermittent problems. typically the part number is located on the cable itself on the side where it pluggs into the main board. since you have a service manual, you should verify it in the manual. good luck.
