BEFORE REPAIRINGTHE COMPACT DISC PLAYER SECTION
. .
Many semiconductors (ICS and transistors) and a pickup (with a bui!t-in laser diode) for reading the music signals on compact discs b means of a laser beam are used as the parts in the compact disc player section.
1) Precautions for handling the pickup and semiconductors (particularly the ICS)
~ The pickup and semiconductors (particularly the ICS) may be da-
maged if they
come into contact with a source of high voltage
static electricity. Do not bring them; therefore, into contact with or into the vicinity of anything which has been charged with high voltage static.
@ The pickup consists of a large number of optical and precision
parts. Do not store or repair it, therefore, in any location with a high temperature, high humidity, high magnetic fields or higtr dust concentration. (Since the pickup contains a powerful magnet.
..
it must not be brought near any magnetized objects.)
... -
@Do not apply strong external pressure to the pickup or subject it to
impact. Actions like these can cause the printed circuit board to crackor malfunctioning to occur.
@Do not use a pickup which has been subjected to strong external
pressure or to an impact. The performance of such a pickup
may
deteriorate gradually and cause malfunctioning.
@ The pickup isa single integrated partwhich has been very precisely
adjusted. Therefore, its adjustment points and set screws must not betouched.
2) How to prevent static during handling @ When replacing any of the parts, disconnect the power plug from
the unit being repaired.
@ All measuring instruments, tools and repair equipment must be
grounded. Cover the work bench where the repair work will be done with a grounded electrically conductive sheet.
@ Ground the metal part of the soldering iron in order to safeguard
against leakage of electricity from the heater.
@ Repair personnel must wear grounding bands around their wrists
to discharge static picked up by their bodies. These bands are grounded through a resistor (with a 1M ohms resistance).
-2-
Note: Under no circumstances must be the grounding bands be grounded wit%out a resistor (with a 1M ohms resistance) since do­ing so involves the risk of electric shocks.
Since static in the clothes of the repair personnel will not be dis­charged by wearing grounding bands, every care must be taken not to allow the clothes to touch the pickup and semiconductors (particularly the ICS).
,.,
@ The pickup, which is a single integrated part, is kept in a conduc-
tive bag. Use this bag to convey the pickup from one place to an­other. In order to avoid damage resulting from static which may occur when the pickup is removed from the bag, make sure that it is not placed on top of the bag.
3) Precautions with laser beam ~ DO not look straight at the laser beam from the pickup and do not
point the beam at your fingers or any other part of your body. Note: The laser beam must never be allowed to enter the eyes since this may damage the eyes.
@ Power
must never be supplied to a pickup with a damaged laser
output part (objective lens, etc.).
4) Cleaning the lens surface ~ Blow off dust on the lens using the kind of air brush which is used
for cameras.
@ Remove stubborn dirt with a cotton swab dipped in isopropyl alto.
hoi. Do not use any other type of cleaning fluid since it may mark the plastic
lens.
Notes: ~ Do not use too much isopropyl alcohol:
the excessmayseep in
side the pickup.
@ The lens is held in place by a very feeble support spring. There
fore, when cleaning the lens, avoid applying any more force b) the cotton swab than is necessary since this may bend the sup port spring out of shape.

Replacing and lubricating the pickup
Pull out the two pickup rails (CN(143)from the chassis (CM50). The pickup (CM52) can now be ‘&moved once the two pick­up rails (CM43) have been taken out. When the pickup has been replaced, be sure to wipe the two pickup rails (CM43) cleanly and apply grease (FLOIL G­474B) around the entire circumference of the rails and along their entire length.
Pass the two pickup rails (CM43) through the new pickup (CM52), insert them into the chassis (CM50), and fix them in place at an angle of 45° as shown in the figure.
Notes:
a. When applying the grease, do not allow any
grease to adhere to any other parts.
b. If a part (indicated by the do;s in the figure) of
the chassis (CM50) is damaged in the process of re­moving or inserting the two pickup rails (CM43) from or into the chassis (CM50), wipe the damaged area with a cloth dipped in alcohol (normal hex­ane), and bond it together using a bonding agent (Cemedine #575).
