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.

Design and specifications are subject to change without

notice.

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 pick-

up 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

PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR

IN SUPPLEMENTS PUBLISHED BY SONY.

CHUCK PLATE JIG ON REPAIRING

LASER DIODE AND FOCUS SEARCH OPERATION

CHECK

1. Turn ON the POWER button and press FUNCTION button to

CD position.

2. Open the lid (CD).

3. Turn on S801 with screwdriver, etc. as following figure.

4. Press the CD N X button.

5. Confirm the laser diode emission while observing the objecting

lens. When there is no emission, Auto Power Control circuit or

Optical Pick-up is broken.

Objective lens moves up and down three times for focus search.

On repairing CD section, playing a disc without the lid (CD), use

Chuck Plate Jig.
