Question about Kenwood KDC-X811

1 Answer

No power, does not open

I have owned it since new and it's been working great until it just stopped working. I checked all the wiring and all is good, fuse is good. It started out that the face would sorta get slower on opening or stop 1\2 way and try to restart and now it just doesn't open even if you try to manually open it. I get not sound, no movement anymore. Anybody have an idea what it may be? I rather keep this head unit instead of buying a new one if this would be an easy fix.

I have a new 1 week Kenwood DNN991hd and it keeps resetting on its own, changing all of my audio EQ, etc settings back to default. Is there a way to stop this?

Did you forget to hook up the wire that holds memory? Maybe you connected it to a wire that looses power when the key is off. Check it for power with the key off. If no power then move the wire to one that does have power all the time.

Unit has no power

It could be a faulty fuse or you could have a short in the wire somewhere. Check along any rub points on the wire.

Buttons stopped working

sounds like you may have a bad switch. if you have a multimeter you can check to see if a switch is reading less then a few megaohms. if one is reading a few kilo ohms, it is probably bad.

My Pioneer DEH-P860MP has had an issue to where it will power-up and down on it's own. Sometimes power will flash, which I can tell as the display may illuminate for a brief moment and/or the faceplate...

you may have a bad flexible cable that goes from the face to the main pc board. there are two cables, one that goes to the upper face and another that goes to the lower fac. typically the one that goes bad is the lower.

Panasonic R 805e with cd shuttle

I had a similar sounding problem with my stereo and got the following response here...

"It sounds like a bad ground wire connection-you want to check the rear of the head unit and make sure that your wire harness is very secure to the unit clip the ground wire and run your own ground wire to somewhere-anywhere where you can safely ground that wire to the chassis I actually attached my ground to the rear of the cigarette lighter because you KNOW that it has a dam good ground to manage all the current it takes to light them coils orange like that"

I took the advice and it worked out great! Give it a try and see what happens.

Twice my Pioneed DEH-P7900BT has just stopped working. Keyboard went dark and the unit shut off. I pressed the button to open the face place and it opened and is stuck that way. It also didn't eject my CD...

This sounds like a wiring problem. Double check all of you connections. If the Connections look good then I would check the connections inside the radio. Check the power wire mostly. The wire could have a bad solder joint inside the radio itself.

Volume fade

Check to be sure there are no speaker wires touching ground, and that the wires are connected in phase to the head unit.
Front Speakers 5 1/4" Doors Left Front (+) Green Left Front (-) Black/White Right Front (+) White/Red Right Front (-) Black/White Rear Speakers 6" x 9" Rear Deck Left Rear (+) Pink/Red Left Rear (-) Pink/Blue Right Rear (+) Pink/Light Blue Right Rear (-) Green/Red

The symptoms you are relaying definately sound like an internal amplifier problem. It is fading in and out for a reason - usually due to heat.

Have you had the radio bench tested (seperate from the car) to eliminate the car as being the culprit?

Since the radio was run with damaged speakers originally, the output or amplifier power supply on the amplifier may be bad.

As an alternative to repairing, I would suggest investing in a small 2 channel amplifier to power the speakers.

The radios claim 50W per channel, but in reality give 12-15W RMS power.

A dedicated amplifier with built in crossovers and gain adjustments will prolong the life of your speakers and add to the tonal qualities of your new speakers. Instead of turning up the volume on the head Unit, and sending out a distorted signal that will blow your speakers, an amplifier will give more CLEAN power to them, so it will be louder at a lower volume setting.

This will bypass the internal amplifier on the radio, and send a Low Level signal ONLY thru a set of RCA cables.

Good Luck!!

Audio quit suddenly

Sounds Like your pr-amps are shot. You may have incorrectly wired the power lines up. If you are handy with a meter and check the middle legs of the pre-amps and see that you have continuity one way and none the other. If this isn't the case then they are shot or whatever ones dont pass this test. pop them out and order new ones. About $20.00
