Hi!

I have the above mentioned CD player, pulled from a soggy cardboard box on
trash day, along with some computer monitors and other stuff. The monitors
have all been fine apart from some cleaning and the VCR has been working
fine after I got it dried out. That leaves me with the CD player. It looks
to be in awfully good condition for its age (not a scratch anywhere on it,
not even on the display panel) and it powers right up with no problem. At
present it has no problem reading the index of a disc, and it will play the
middle and end of a disc with no problems. The only thing it won't do is
play the beginning of a disc. I can see the spindle motor spin up and down
and I can hear the laser sled moving around from time to time as the motor
speeds up and down.

I can only see one thing that's amiss when all of this is going on. The
spindle motor seems to be having some moderate degree of difficulty coming
up to speed. It seems to do so for the most part, but it takes what I feel
is a rather long time. I am thinking that the spindle motor could be
partially shorted and in need of a cleaning. I cannot check the temperatures
of any driver components at present, because the components are on "the
wrong side" of the boards.

What I'm looking for is anyone who might have a CD player similar to this
one in working order, for reference purposes. I'm curious how quickly the
spindle motor in your player takes to come up to speed. If there is anyone
out there who has seen a similar problem (like what are my chances...but
there's no harm in asking...) with this player?

Thanks in advance for any thoughts, tips, etc!

It may be a partially shorted spindle motor - very common in many CD players.

See: http://repairfaq.ece.drexel.edu/sam/cdfaq.htm#cdpwspmm

The spindle motor has to spin faster on the inner tracks and can't make it.

I doubt it's the servo IC as someone else mentioned. Could be mechanical
though - deteriorated rubber parts, gummed up grease, etc.
