SKIPPING Disc CHECKLIST
Douglas McCallum
Shiawassee Technical Services
Lansing, Michigan
SYMPTOM
Rowe CDs skipping
CAUSE
-
Skipping CD player in juke. Iso-
late the problem. Skipping means
the player can't maintain track-
ing. It's either responding to ex-
ternal forces or it is incapable on
its own of proper tracking.
SUSPENSION
Good suspension should prevent
skipping from bumps, though
high volume low frequency
sound vibration could cause
trouble.
PLAYER
Does your symptom only occur
at high sound levels?
If it skips even when no one
bumps it and while it is playing
at lower levels, then it is the
player itself.
BINDING
Make sure nothing can interfere
with the works mechanically, like
~ a wire that can rub the CD or a
cable that gets pushed up under
the sled (optical pickup).
You cleaned your CDs, but
do you clean your lenses?
In home stereo CD players, that
is 900/o of the service need. You
can blow off dust, but the tar and
nicotine from smoke will film the
optics.
PROCEDURE
Use lens cleaning solution or iso-
propyl alcohol. Get real pure iso-
propyl, not rubbing alcohol, ask
the druggist. Rubbing alcohol
can contain oils for skin lube.
Use a Q-tip or a foam swab wet
with cleaner and gently gently
clean the lens, then clean it again.
Accumulating dirt on the lens
would be consistent with a skip-
ping problem that slowly gets
worse over time.
The optics lens is supported on
tiny coils which move it around
to maintain focus and tracking.
It is very tender. Hold the Q-tip
lightly and apply minimal pres-
sure to the lens, gently wiping
sideways.
