Default Sony CDP-C325

Hi all,

I have a Sony CDP-C325 5 CD carousel player with a problem. When
changing discs, sometimes the new disc won't start playing.

The scenario is:
- whatever disc is playing finishes
- the disc stops spinning and lowers into the carousel
- the carousel rotates the new disc into position
- the new disc raises from the carousel
- the track calendar displays the tracks of the new disc
- "Track 1" appears on the main display
- then nothing

The newly raised disc does not start to spin, the play clock does not
display and the unit just hangs until it is manually taken out of
"play" mode. This can be done by stopping/restarting, changing tracks
without stopping or even just by seeking within track 1. As soon as
that hung "play" mode is cancelled, the disc will spin up and play
normally.

The problem is not tied to any nest, it happens about 50% of the time
on any change - occurring both on sequential disc advance and on
manual disc selection which can change to any nest.

The unit has been in the local repair shop twice. The technician
first replaced the laser module (unnecessarily I now believe) which
did not help and now claims he can't find anything wrong. I really
don't want to take it back to him but there aren't any other repair
shops close by.

My unit is 10 years old and I know it isn't worth spit - a replacement
can be had for $100. But right now I'm ****ed off and I want to know
what's wrong with it. Has anyone seen behavior similar to this and,
if so, do you know the cause?

Thanks everyone,
George

I have a CDP-C435 which I believe is from the same era. I have had a similar
problem with it in the past which I found was due to the carousel being
slightly out of alignment, i.e. it appeared to have slipped a cog in the
gearing between it and the motor. I found that by taking the top cover off
and removing the center screw holding the carousel down, I could lift the
carousel up and move it around slightly to bring it into the right
alignment. I don't know it your problem is the same because I don't recall
if, in my situation, the newly selected disc raised from the carousel or
not.
By the way, I stick with my CDP435 because it has some very valuable
features which I cannot find on any of the current 5 disc players including
Sony models.

Of course the lens should be cleaned, and other maintenance done, but this
problem is usually caused by the sled limit switch not quite making contact.
Common problem.

Thanks for the suggestion.

I don't know how common it is. I also have a C500 in another room and
among my siblings there are three more Sony carousel units - different
models but all of similar vintage (10-15 years old). All have been
moved cross country multiple times and until now none of them have
ever required more than a simple cleaning.

I don't have a repair manual for the C325, is the sled limit switch
easy to check? And where do I get parts?

The switch is stand-up mounted on a circuit board underneath the pickup.
Kind of hard to get to.

Thanks. I'll see if I can get a look at it.
