SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK ! OR DOTTED LINE WITH

MARK ! 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.

CAUTION

Use of controls or adjustments or performance of procedures

other than those specified herein may result in hazardous radiation

exposure.

Flexible Circuit Board Repairing

· Keep the temperature of the soldering iron around 270

°C during

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.

Notes on chip component replacement

· Never reuse a disconnected chip component.

· Notice that the minus side of a tantalum capacitor may be damaged

by heat.

DANGER

Invisible laser radiation when open and interlock failed or defeated.

Avoid direct exposure to beam.

This Compact Disc player is

classified as a CLASS 1 LASER

SERVICING NOTES

NOTES ON HANDLINGTHE 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 from

more than 30cm away from the objective lens.

Before Replacing the Optical pick-up Block

Please be sure to check thoroughly the parameters as per the "Optical

pick-up Block Checking Procedure" (Part No. : 9-960-027-11) issued

separately before replacing the optical Pick-up block.

Note and specifications required to check are given below.

· FOK output : IC501

!TM pin

When checking FOK, remove the lead wire to disc motor.

· S curve P-to-P value : 0.9 1.5Vp-p IC501

#¡ pin. (Connect pin

!TM of IC501 (TP880) and 3 of IC501 (GND) with a jumper

wire).

When checking S curve P-to-P value, remove the lead wire to

disc motor.

· Adjusted part for focus gain adjustment : RV503

· RF signal P-to-P value : 0.85 1.15Vp-p

· Traverse signal P-to-P value : 1.0 2.6Vp-p

· The repairing grating holder is impossible.

· Adjusted part for tracking gain adjustment : RV502

Precautions for Checking Emission of Laser Diode

Laser light of the equipment is focused by the object lens in the

optical pick-up so that the light focuses on the reflection surface of

the disc.

Therefore, be sure to keep your eyes more then 30cm apart from

the object lens when you check the emission of laser diode.

Laser Diode Checking Methods

During normal operation of the equipment, emission of the laser

diode is prohibited unless the upper panel is closed while turning

ON the S801 (push switch type).

The following two checking methods for the laser diode are operable.

Method-1 (In the service mode or normal operation) :

Emission of the laser diode is visually checked.

1. Open the upper lid.

2. Push the S801 as shown in Fig. 1 .

3. Check the object lens for confirming normal emission of the

laser diode. If not emitting, there is a trouble in the automatic

power control circuit or the optical pick-up. During normal

operation, the laser diode is turned ON about 2.5 seconds for

focus searching.

Fig.1 Method to push S801

Method-2 (In the service mode or normal operation) :

Check the value of current flowing in the laser diode.

1. Remove the upper panel.

2. Read the current printed on the rear side of the optical pick-up.

(Print on the rear side of the optical pick-up)

3. Connect a level meter as shown in Fig. 2

4. Press the ^ key.

5. Calculate the current value by the reading of the digital voltmeter

Reading of the tester (V)

÷ 4.7 ( ) = current value (A)

(Example) Reading of the digital voltmeter of 0.2256 V :

0.2256 V

÷ 4.7 = 0.048 (A) = 48 mA

6. Check that the current value is within the following range.

Current value of the label

mA(25

°C)

Variation by temperature : 0.4mA /

°C

Current increases with as temperature increases.

Current decreases with as temperature decreases.

If the current is more than the range above, there is a trouble in the

automatic power control circuit or the laser diode is in deterioration.

If less than the range, a trouble exists in the automatic power control

circuit or the optical pick-up.
