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 do-

ing so involves the risk of electric shocks.

Since static in the clothes of the repair personnel will not be dis-

charged 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 placeto an-

other. 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

~ DOnot 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 excessmay seep 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.

Preparations

Do not apply unnecessary force to the pickup when handling it.

Care should be taken not even to touch the lens or drive

circuit sections.

Do not apply unnecessary force (do not pull or push it forcefully) to remove the disc tray from its inside position.

Unnecessary force may break theteeth onthetray gear (CM6).

In the descriptions which follow, the numbers in the parentheses after the parts are reference numbers in the exploded views.

Refer to these views.

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 pick-

up 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 G-

474B) 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 re-

moving or inserting the two pickup rails (CM43)

from or into the chassis (CM50), wipe the damaged

area with a cloth dipped in alcohol (normal hex-

ane), and bond it together using a bonding agent

(Cemedine #575).

ADJUSTMENT OF TAPE DECK

1. Azimuth Adjustment

. Be sure to clean the heads before attempting to make any adjustment.

. Be sure both channels(l and 2) are the same level (Using a dual-channel oscilloscope),

. Be sure both cannel’s waveform are same for the phase matching.

. After completion of the adjustment, use the thread lock (TB-1401B) to secure the azimuth adjustment screws.

(l). DECK A

~. Load a test tape (VTT-703 etc. : 10kHz) in deck A.

Q. Press the PLAY button. (normal playback)

@. Use a + tip screwdriver to turn the screw for normal azi-

muth adjustment so that the left and right outputs are

maximized at the same phase during normal playback.

(2). DECK B

~. Repeat procedure for deck B.

Notes : 1.

3. Parts

For making adjustment of step 1, set the DECK B mechanism ts record made with C-60 blank cassette tape.

Adjustment should be made at the ending portion of the tape.

Confirm the indication of the tape speed for 2 second after adjustment has been made and adjusting driver has been re-

moved from SVR on the TAPE DECK AMPLIFIER P. C. Board.

For adjustment, use the screwdriver with Isolated tip from grip.

For high speed check, short the test points (High-SPEED) to chassis ground on the TAPE DECK AMPLIFIER P. C. Board, (Test

Tape is TCW-21 1) and confirm that the speed of DECK B is in -40-70 Hz against DECK A.

when the CD, TUNER, TAPE DECK and et~ operation buttons are pressed, press the RESET switch and initialize the microprocessor

following the step below.

1).

2).

3).

Disconnect the AC power cord from the power outlet.

Keep the RESET switch depressed for 60 seconds.

PARTS LIST

PRODUCT SAFETY NOTICE

Each precaution In this manual should be followed during servicing. Components identified with the IEC symbol ~ in the parts list

and the schematic diagram designate components in which safety can be of special significance. When replacing a component identi-

fied ~, use only the replacement parts designated, or parts with the same ratings of resistance, wattage or voltage that are desig-

nated in the parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts

are acceptably insulated from the supply circuit before returning the product to the customer.

CAUTION: Regular type resistors and capacitors are not listed. To know those values, refer to the schematic diagram.

N.S.P

: Not available as service parts.
