Car cd changer

I have a Kenwood KDC-C712. The face plate read "E-99" whilst changing a cd, then i tried to eject the magazine, but it wont come out when i press the button on the changer. The part that pulls out the cd's from the magazine moves a little, then moves back again. The unit humms a little when this happens. Can i fix this myself?

Yes. open it up and find the small motor that performs the eject process. Then turn it by hand to eject the magazine.

I have a Kenwood KDC-252U stereo and it is stuck in the protect mode. I followed the instructions the best I can. Any help would be wonderful.

any relations with jack frost? protection comes on if you run it too loud but if its on all the time that would mean your internal speaker output is faulty. you have to tip it

Have you tried to check all buttons on the face, for a stuck button? Carefully examine all corners of buttons for a problem. Try to gently pry it free using a toothpick, if found.

6 cd changer in 2001 ford expediation

If the unit will not accept or eject any disks, this is a relatively simple fix. Remove the unit from the vehicle. There are 4 T-9 torx screws on the side of the radio. Remove them and slightly lift the CD mechanism from the radio. There are 2 things that need to be unplugged before you can separate the 2 pieces. The 2 wires simply unplug from the bottom of the cd mechanism. The ribbon cable is locked into the socket, you need to grab the lock and gently pull it away from the circuit board. When unlocked the ribbon cable will simply fall out of the socket. Look through the front of the changer mechanism, are there any disks that look out of place? Gently lift the trays to inspect the disks, if one of the disks is too far back you need to get it into place. Reassemble the deck and see what happens.
