SERVICE NOTE
TABLE OF CONTENTS
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
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.
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
breakdown because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown 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 pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
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
P ART NUMBERS APPEAR AS SHOWN IN THIS MANU AL OR
IN SUPPLEMENTS PUBLISHED BY SONY.

• C : panel designation.
Note: The components identified by mark 0 or dotted line
with mark 0 are critical for safety.
Replace only with part number specified.
• U : B+ Line.
• Power voltage is dc 14.4V and fed with regulated dc power
supply from ACC and BATT cords.
• Voltages are taken with a V OM (Input impedance 10 MΩ).
Voltage variations may be noted due to nor mal production tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to nor mal production tolerances.
• Circled numbers refer to waveforms.
• Signal path.
F: FM
f: AM
J: CD
for printed wiring boards:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
a
•
: Through hole.
• b : Pattern from the side which enables seeing.
(The other layer’s patterns are not indicated.)
Caution:
Pattern face side: Parts on the pattern face side seen from the
(Side B)pattern face are indicated.
Parts face side: Parts on the parts face side seen from the
(Side A)parts face are indicated.
