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.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0OR DOTTED
LINE WITH MARK 0ON 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 PUB-
LISHED BY SONY.
The laser diode in the optical pick-up block may suffer electro-
static 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 emis-
sion, observe from more than 30 cm away from the objective lens.
SERVICE POSITION
In checking the CD block, prepare jig (extension cable J-2501-
011-B).
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
Connect jig (extension cable J-2501-011-B)
to the MAIN board (CN101) and VCD block (CN502).

2. Turn the adjustment screw and check output peaks. If the peaks
do not match for L-CH and R-CH, turn the adjustment screw
so that outputs match within 1dB of peak.
3. Mode: Playback
4. Repeat step 1 to 3 in playback (REV) mode.
5. After the adjustments, apply suitable locking compound to the
pats adjusted.

WS-48B 3 kHz, 0 dB Tape Speed Adjustment
P-4-L300 315 Hz, 0 dB Level Adjustment
Note: Confirm each contents of this section first of all. If the results are
not satisfied, do the adjustment.
1. Demagnetize the record/playback head with a head
demagnetizer.
2. Do not use a magnetized screwdriver for the adjustments.
3. After the adjustments, apply suitable locking compound to the
parts adjust.
4. The adjustments should be performed with the rated power
supply voltage unless otherwise noted.
5. The adjustments should be performed in the order given in this
service manual. (As a general rule, playback circuit adjustment
should be completed before performing recording circuit
adjustment.)
6. The adjustments should be performed for both L-CH and R-
CH.
7. Switches and controls should be set as follows unless otherwise
specified.

CD SECTION
Notes:
1. CD block basically constructed to operate without adjustment. There-
fore, check each item in order given.
2. UseYEDS-18 disc (Part No.: 3-702-101-01) unless otherwise indicated.
3. Use the oscilloscope with more than 10 MΩimpedance.
4. Clean an object lens by an applicator with neutral detergent when the
signal level is low than specified value with the following checks.
S-Curve Confirmation
Connection:
Procedure:
1. Connect an oscilloscope to IC703 pin qg and TP (VC) on the
CD board.
2. Connect between TP (FOK) and TP (GND) on the CD board
by lead wire.
3. Turn the power ON.
4. Press the [EJECT ] (CD) button to open the disc tray, and
put the disc (YEDS-18).
5. Press the [EJECT ] (CD) button to close the disc tray (Actu-
ate the focus search).
6. Confirm that the waveform on the oscilloscope is symmetrical
between A and B and that peak to peak level is within 3.0 ±
1.0 Vp-p.
S-curve waveform
7. After confirmation, disconnect the lead wire in step 2.
Note: • Try to measure several times to make sure that the ratio of A : B
or B : A is more than 10 : 7.
• Take sweep time as long as possible and light up the brightness
to obtain best waveform.
RF Level Confirmation
Connection:
Procedure:
1. Connect an oscilloscope to IC703 pin qh and TP (VC) on the
CD board.
2. Turn the power ON.
3. Load the disc (YEDS-18), and press the [ ] button to play-
back the disc.
4. Confirm that the waveform on the oscilloscope is clear and
that the RF signal level is correct.
Note: Clear RF signal waveform means that the shape “◊” can be clearly
distinguished at the center of the waveform.

5-4. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
Note on Printed Wiring Boards:
•X: parts extracted from the component side.
•Y: parts extracted from the conductor side.
•W: indicates side identified with part number.
•: Pattern from the side which enables seeing.
• Indication of transistor.
Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ωand 1/4W or less unless otherwise
specified.
•f: internal component.
•C: panel designation.
•A: B+ Line.
•B: B– Line.
•H: adjustment for repair.
• Voltages aretakenwith aVOM(Input impedance10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.
