Dennis,
This is a email I received from a list member over a year ago being that I was having the same problems with my stock Delco CD player and it won't even play now.
Your player will fail to accept a disc for (at least) the following reasons:
1. Disc RPM did not reach proper speed for the inner hub within a set
amount of time.
2. The player failed to interpret the information on the disc TOC (table of
contents).
The first item is usually a bad motor or a bad supply to the motor. The
second item is the more common of the two and can be caused by several
things. I'll list them in order of "easiest" to most difficult.
First; the disc (CD) TOC may be damaged. If you look at toward the inner
hub of the disc, just past the bright "inner reflective" ring, you will see
a thin line that extends out about 2 mm. This is the table of contents and
contains all of the information about the disc to initialize your player
(i.e. number of tracks, length of tracks, etc.). Any scratches in this area
are bad. The information is repeated 3 times in case of damage; however, a
bad scratch to either the mirror (bottom) or replicated side (printed side)
can take out all 3 lines of code.
Second, the laser optics may be dirty or scratched. This can cause the
laser light to be refracted in such a manner that it cannot focus correctly.
If it just needs to be cleaned its no big deal; scratched optics essentially
would cost more to repair than the price of the player. One note, however,
don't buy a "cleaning CD". These products are a scam and they can damage
your player. They do not work.
Third; the laser optic pickup circuit, the laser servo sled, or the laser
focus mechanism may be damaged. These are all bad. Individual parts are
not user serviceable, are expensive, and are hard to troubleshoot.
I don't think I painted that rosy of a picture for the future of your
player. You may get lucky and find just dirty optics; try removing the
cover and using a Q-tip with rubbing (isopropanol) alcohol to GENTLY swab
the optics.
Hope this helps. Just as a reference; I'm not a geek who had nothing better
to do than spend his whole life studying CD's, it's my job. I am an
operations manager for Sony Disc Manufacturing. I've been in management too
long, my mind gets fuzzy on some details regarding the players but this is
very close when discussing in layman's terms.
So bottom line, it sounds like the motor for the CD player. Anyone have a perfect playing stock Delco AM/FM CD player for a '93 Ty for sale?
Later,
