Sony CD changer won't open

[MJH]

This is a long shot, but I've been impressed with the expertise on this
board....

I have a 10 or so year-old Sony CDP-C70 5 disc CD changer...it worked fine
until I transported it to another location. Now the disc tray won't open
(it normally extends out from the case to load the CD's). I took off the
top and made sure nothing was jammed inside. Further, it won't even play a
disc loaded into the space above the laser. Obviously something got messed
up during transport, but nothing I can see....any clues?

thanks

Usually just have to take out the tray etc and mess around with the timing
until it works. Pretty common.

I agree that the problem is very likely to be mechanical. My initial
approach in a situation like this is to take it apart and put it
carefully back together again. Before beginning, take careful notes of
the position of screws, washers, and springs. Just the simple maneuver
of taking apart and putting it back together again often resolves these
problems. Good luck.

Also take pictures, several of them, from different angles; and at each
stage of disassembly...even a video wouldn't hurt.

The last time this happened to me, a disk was left in the changer, it was
powered up and the disk jammed the mechanism. A very small plastic piece
was broken off which was supposed to trip a lever. It took a good deal of
minute examination to discover.

I realize that the OP stated that nothing was jammed inside, but the part
about minute examination still pertains. He should manually run the changer
through it's processes and thoroughly gain an understanding of how each part
of the mech' relates to the others.

OTOH, the first thing is to unseat and reseat all ribbon connectors.....

And certainly you have checked the most common fault on a unit of te
years of age ? A sagging/slipping/or/ broken belt on the DC drive moto
that
drives the support/carriage tray in and out. Considering that motor i
heard running when you initiate a tray open/close switching.

These Sony's use a gear-belt for the tray in / out drive.
Never seen one go bad. It's probably a mech timing issue - someone grabbed
the tray while it was running in / out.
