SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK A OR DOTTED LINE
WITH MARK A ON THE SCHEMATIC DIAGRAMS AND IN THE

REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE
PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN
SUPPLEMENTS PUBLISHED BY SONY.
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
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 pick-up
block. Therefore, when checking the laser diode emission, observe
more than 30 cm away from the objective lens.
[ CHUCK PLATE JIG ON REPAIRING
On repairing CD section, playing a disc without the CD lid, use Chuck
Plate Jig.

Note :
1. CD Block basically constructed to operate without adjustment.
Therefore, check each item in order given.
2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.
. Use the oscilloscope with more than 10MQ 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.

1. Connect oscilloscope to test point TP (VC) and TP (RF) on BD
board.
. Ground main board IC101 (pin@) with the lead wire.
Turned power switch ON. (Stop mode)
. Put disc (YEDS-18) in and press the B> button.
. Press the #9 button. (Tracking servo ON)
. Adjust RV101 so that the oscilloscope waveform is as shown in
the figure below (eye pattern).
A good eye pattern means that the diamond shape (0) in the center
of the waveform can be clearly distinguished.
7. After adjustment, remove the lead wire connecd in step 2.

Procedure :
1. Connect oscilloscope to test point TP (FEO) and BD bo ard.
2. Connect between test point TP (FOK) and TP (GND) by lead wire.
3. Turned Power switch on.

4. Put disc (YEDS-18) in and turned Power switch on again and
actuate the focus search. (actuate the focus search when disc table
is moving in and out.)
5. Check the oscilloscope waveform (S-curve) is symmetrical
between A and B. And confirm peak to peak level within
2.4+0.7Vp-p.

6. After check, remove the lead wire connected in step 2.
Note: @Try to measure several times to make sure that the ratio of
A:BorB:A is more than 10: 7.
@Take sweep time as long as possible and light up the brigh-
ness to obtain best waveform.

Focus/Tracking Gain Adjustment (RV102, RV103)
This gain has a margin, so even if it is slightly off. There is no prob-
lem.
Therefore, do not perform, this adjustment.
Please note that it should be fixed to mechanical center position when
you moved and do not know original position.
