Question about Sony CDP-CE375 5-Disc CD Changer
Carsousel tray will not open. I have tried the power off/unplug/wait 30 plus seconds/power up method, but with no luck. There is no CD stuck in the player (I removed the cover and checked.) Sony service tells me it will definitely cost more than $200 to repair. I'm looking for some other possible solution. Any help is appreciated. (And yes, I do have another "contemporary" CD/DVD player.)

The slider mechanism, depending on the age of the unit and the
manufacturer, consists of the small chrome rail, a drive motor, a small
gear assembly, and (in some units) a small belt that drives the slider
unit via the motor. This small belt causes all sorts of problems. If
the belt is broken or slipping, it can cause skipping, dropouts, or
simply no start up at all. Also, if the belt breaks in the middle of
the disc, the drive mechanism gets hair or dirt wrapped up into the
gears, or the pick-up assembly doesn’t return to the start position
(called home), the unit will (99% of the time) refuse to release the
disc, causing it to become stuck inside the unit. There’s a little
micro or leaf type switch located at home position that sometimes gets
dirty or breaks and, causing this problem also.
If the disc starts to spin slowly and doesn’t come up to speed, the spindle motor that’s attached to the turntable platter is a common problem. There could also be a problem with the spindle motor driver controller IC or the power supply regulator that supplies voltage to the driver IC. If the disc starts to spin and then spins really fast, or stops and starts to spin backwards, your problem is the laser pick-up assembly or the servo control circuit. If you continue to have problems after cleaning and checking the other things listed above, you may have a problem with the player's alignment. Of course, one of the problems you'll face checking alignments on a DVD/CD player is that you’re going to need to use an oscilloscope on most of them. If you have the proper tools and equipment, the first thing to look at is the RF pattern of the unit while its playing. It should be a sharp and clear pattern. If it's dull and smeared, then the laser could be weak.
Also, in these units are very critical alignments called the focus/tracking gains and offsets. When these alignments are off, it can often cause intermittent troubles. As the unit ages and parts change value, so do these alignments, and will need to be checked. In my time as service technician repairing DVD/CD players, 65% of the laser pick-up assembles I have tested were good and only needed a small adjustment. Today's technology makes it unfeasible for a shop to hook up a DVD/CD player, and even some recorders, to their equipment and make these adjustments because of the cost involved.
Hope this may help;

It sounds like there is a cd tray alignment problem, there is no quick fix, all i could suggest is to send it to us or take it to your nearest dealer.

As long as the cd hasn't caused any other damage to the electronics or mechanics of the player, it should be an easy fix. First, open your carousel then unplug the player to avoid shock. Remove the top lid of the player via the screws on the exterior holding it in place. From there, the stuck CD should be right there for you to reach in and remove. Hope this helps!

I had the same problem with our 5-CD Sony carousel player CDP-C535 (manufactured Nov 1993). I removed the top metal cover, and loaded five audio CDs into the carousel. After I closed the table, I pressed the carousel tight so that it stayed close, and hit the play button. The CD player tried to push the carousel out with quite a force. I needed to warp me fingers around the front panel to keep the carousel closed. After a few cycles of forcing the carousel to remain close, and caused two separate strong "clucks" from the gear area, the CD carousel became operational again. The diagnosis of gear problem seems right.
