SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED
LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS
AND IN THE PARTS LIST ARE CRITICAL TO SAFE
OPERATION. REPLACE THESE COMPONENTS WITH
SONY PARTS WHOSE PART NUMBERS APPEAR AS
SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur-
ing repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.
SECTION 1
SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated
by the charged electrostatic load, etc. on clothing and the human
body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.

HOW TO PLAY CD WITH THE DISC TRAY
OPENED
To play a CD by this method, the screws that secure the SERVO
board to the chassis must be removed in advance.
Procedure:
1. Press ! button to turn the power ON.
2. Set a CD on the disc tray.
3. W ith the disc tray opened, connect pin 1 and pin 2 of CN272
on the LOADING MOTOR board using tweezers, etc.
4. As the disc starts to move toward direction A, intercept the
sensor in B section with your finger immediately . (See “HOW
TO OPERATE THE SET WITHOUT USING STABILIZER”
on page 5)
5. You can release your hand when TOC is read.
6. Hence, the operation equivalent to normal operation can be
performed.

SERVICE POSITION OF SERVO BOARD
In servicing the SERVO board, erect the board as shown below.
In this case, the CN201 and CN202 connectors are disconnected respectively, and accordingly the buttons on the front panel do not
function.
Therefore, use the Remote Commander for fundamental operations such as PLAY and STOP.
Also, in performing the service under this condition, the stabilizer is not detected, so refer to “How to Operate the Set without Using
Stabilizer”.
disconnect CN201
SERVO board
disconnect CN202
HOW TO OPERATE THE SET WITHOUT USING STABILIZER
As this set detects the stabilizer, if servicing the set in other than normal operating way, disable the stabilizer detecting function by the
following method.
The stabilizer is detected before TOC is read, and after that, this function does not operate.
That is, the stabilizer detection is executed after power on or immediately after disc loading, and you can release your finger after the disc
was recognized.
Intercept the D202 on SERVO board
with your finger.

1. CD block basically constructed to operate without adjustment. Therefore, check each item in order given.
2. Use YEDS-18 disc (Part No.: 3-702-101-01) unless otherwise indicated.
3. Use the oscilloscope with more than 10 MΩ impedance.
4. Clean an object lens by an applicator with neutral detergent when the
signal level is low than specified value with the following checks.
