My Kenwood KDC-715s will not operate. The problem is the faceplate began to move and stopped. It opened and stopped at the halfway point and that is where it has stayed. It is in the correct position for removing the faceplate, so I did remove it and the backing plate moved back to the home postion. So it does have power. I reinstalled the face plate and it opened back up to the half way position and stopped. All the contacts are clean. This unit has been in servce since 2001' for about 30,000 miles in my car. I hate to think this is a throw away unit but as usual it would most likely be more cost effective to replace the unit instead of sending it out for repair. Any ideas on what the issue is or what to look for? Thanks, Rich.
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.

I don't have a solution for you, but my KDC-715s developed the EXACT same problem a few days ago. I've emailed Kenwood tech support for advice. If they say it has to go to a repair depot, I'll be scrapping it and buying something else. If that happens, I'll have a perfectly good 10 disc changer and cables available for cheap, if you are interested! If Kenwood DOES have a useful answer, I'll post it here. They say it usually takes them a few days to respond.

Kenwood tech support didn't offer much in the way of useful suggestions. They said try the reset button or take it to a Kenwood authorized service center. I scrapped it and bought a Sony that sounds just as good, and cost less than half as much. It will even play wma and mp3's, which the Kenwood would not do. It also comes with a wireless remote! No more Kenwood products for me.

Update on this problem.
I purchased the service manual for this unit from user-manuals.com. Its a pretty good manual but it does not give instructions on how to service it. It does have incredible detail in the exploded view diagrams and if you are mechanically inclined and have a bit of patience you can pretty easily figure things out. I've taken it apart as far as the whole front plate drive assembly and it looks like a tiny switch might be the culprit.
I'm almost sure the problem is with the PS1 switch.
Part# S68-0829-05
I will need to spend more time on it to test this individual switch. I've been taking pictures along the way to record my progress.
If anyone is interested I can E mail pictures. Just let me know.
I will post back later with my results. Although it may be after the holidays.
P.S.
Woodchuck, if you are reading this I hope you didn't scrap your deck yet. I think we can save it. Or if you like I can take it off your hands. $$$?

Thank you for your comment. As it turns out, after further testing, you are 100% correct. I will try to order the flexible cable. I do have another question in regards to installing this cable. Where it passes through the shaft with the torsion spring, do you know how much tension should be preloaded on the spring? When I removed the cable the shaft unwound and I did not notice how many turns it rotated. Seems wierd to have that cable go through the shaft and get wounded. Seems like a stress point and a guaranteed failure over time.
Any thoughts would be appreciated. The service manual isn't much of a service manual as far as describing procedures on how to do something. It basically just gives specifications. I would think that somewhere along the line there must be more inforamtion.
Thanks for your previous reply.

Update.
I was able to buy the flexible printed circuit, part# J84-0106-12 for $12.00, and I was successfull in fixing this unit. It wasn't as easy as I had hoped but it really isn't that difficult. It does require a fair amount of patience and time. I spent a number of hours over the past month studying this unit and gathering information as well as a few tools. I also purchased another used KDC 715s just in case I wasn't successfull in my repairs. Now I have two fully functional KDC 715s head units. Sweet!
If anyone else has this same problem with this model feal free to contact me. I will gladly help in any way I can. I have many digital pictures that I took along the way. Thanks to all who replied on this.

What do you mean? "Could you send me what you sent the first guy?"
What kind of help do you need? Are you refering to a disfunctional KDC 715s?
Let me know as I have successfully repaired two of these so far.

Hi Guys
Thanks your information has been very useful. Looking at the head unit, I guessed it may be the flexible printed circuit as it is the weakest link. I have order the J84-0106-12 . If you have any pictures os service manual you can send me to help me fit it, I would be most greatful. This is a real design issue of the unit.
