Pioneer 100 disc CD player problems

intermittently "skip". I did confirm this to be so and I subsequently
slightly increased the setting on the laser pot. The unit seemed to be
OK after that and I put it away for several months. I now have a use
for it and got it out of the closet and loaded it up with CD's only to
find that its doing the same thing once again. The strange thing is
that some CD's seem to be affected worse than others. In fact some
CD's will play fine and others have skips many times in the same
places on the same particular disc when repeated plays are attempted,
while other discs are not recognized at all. There are random skips at
times on some CD's as well. I know that some CDR's could be a problem
with some older machines and so we are not attempting to play any of
those. I was hoping to note the particular CD, track, and time into
the recording and if there was failure repeatability, use that to
determine if my adjustments solve the problem but I don't know if this
method would work or not. Does anyone have any opinions on that? Could
some sections of a CD be harder for what I'm assuming to be a weak
laser to "see" than others? Can someone please explain this
phenomenon to me? I'm going to try to tweak this thing again but I
would just appreciate a better understanding of this. Thanks, Lenny

Check for dust in the optics. Sometimes you can luck out adjusting a
laser by the seat of your pants, sometimes not.

Spindle motors on Pioneers also cause skipping. Check the RF output
with a scope to see if the out put is at the right level and the "eye"
looks sharp. If the level is correct and eye is sharp, I'd lean
toward the motor being faulty. Chuck

Funny, I feel exactly opposite. I've replaced far more Sankyo, Sanyo,
Toshiba, Canon micro motors in warranty repair than Pioneer. Maybe it was
just the stuff I was working on but Pioneer was a covered item.

Interesting. All of my Pioneer disc changers (except one, a RadioShack
branded unit) have developed faulty spindle motors. One has a motor
with a dead spot, all of the others seemed to be the result of crud
build up inside that would partially short the motor.
They're all of various vintages, the oldest at 1990 and the newest
from 1999.

Can't fault the motor for failing due to crud unless the crud was from
the motor itself.

Spindle motors were a common problem on most of the multiplayers that
Pioneer produced, and the lasers were extremely reliable. However, as I
recall, the 100 disc player uses a later deck assembly, and I have had a few
of those develop faulty lasers

I can't think of anywhere else the crud would have come from...my
house isn't immaculate but it's not too dirty either. And all of these
players live in different environments--one is even in a different
building entirely.
The six disc player (oldest of the bunch) was purchased in 2001 with
the problem already evident, so you can't blame my housekeeping for
that! :-)

The problem is the drive voltage/current....

I guess that I could monitor the voltage at the motor terminals while
playing a CD and see if it varies during a skip. Other than that in
light of what everyone has said regarding the possibilities here how
would I reliably rule out a motor or laser as the culprit? Lenny.

In my experience, the only way to *reliably* rule out either, is by
substitution. Not very technical, and not, I'm sure, what you probably want
to hear. All I would say is that on the older Pioneers that tend to use a
deck installed upside down, spindle motor trouble is usually characterised
by slow running with sometimes an accompanying 'squeal', or a failure to
start the disc rotating unless you 'help' it. Skipping or general poor
playability, is normally down to either the deck suspension rubbers, or
wrong setup, including the laser output which, contrary to almost any other
laser, is actually included in the setup instructions. I have found it
*extremely* rare to get a laser which is genuinely faulty itself - unless of
course, you include the well known 'lens fallen out' syndrome ...
On the other hand, the later lasers fitted into the multiplay 'jukebox'
machines that employ a deck mounted vertically, I have had trouble with, and
over the years, I have had to replace several.
