CAUTION

Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

This Compact Disc player is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT table is located on the bottom exterior.

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.

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 P ARTS WHOSE P ART NUMBERS APPEAR AS SHOWN IN THIS MANU AL OR IN SUPPLEMENTS PUBLISHED BY SONY.

ATTENTION AU COMPOSANT AYANT RAPPORT

À LA SÉCURITÉ!!

LES COMPOSANTS IDENTIFIÉS P AR UNE MARQUE 0 SUR LES DIAGRAMMES SCHÉMA TIQUES ET LA LISTE DES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE REMPLACER CES COMPOSANTS QUE PAR DES PIÈCES SONY DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU DANS LES SUPPLÉMENTS PUBLIÉS PAR SONY.

SECTION 1

SERVICE NOTE

• 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. Therefo re, when checking the laser diode emission, observe from more than 30 cm away from the objectiv e lens.

• To Check the Laser Diode and Focus Searc h Operation

Open the upper panel. Turn on the power without a disc while the main board S801 (OPEN) is ON (or T AP802 is shorted). Then, observe the objective lens and check that the following operations are performed.

1. Scatterd light of laser beams is seen.

2. Check for vertical movements (five) of the objecti ve lens (with

movement of the PU on the inner circumference).

– MAIN BOARD – (SIDE A)

• Before Replacing the Optical Pick-Up Block

Please be sure to check throughly the parameters as par the “Optical Pick-Up Block Checking Procedures” (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 : IC601 eg pin When checking FOK, remove the lead wire to disc motor. When checking FOK value, remove the lead wire to disc motor.

• RF signal P-to-P value : 0.46 - 0.66 Vp-p

• The repairing grating holder is impossible.

DIAGRAMS

CD section adjustments are done automatically in this set. In case of operation check, confirm that focus bias.

4-1. FOCUS BIAS CHECK

1. Connect the oscilloscope between TP629 (RF) or TP652 (RF) and GND on main board.

2. Insert the disc (YEDS-18). (Part No. : 3-702-101-01)

3. Press the N > button.

4. Confirm that the oscilloscope waveform is as shown in the figure below. (eye pattern) A good eye pattern means that the diamond shape ( ) in the center of the waveform can be clearly distinguished.

• RF signal reference waveform (eye pattern)

VOLT/DIV : 20 mV (10 : 1 probe in use) TIME/DIV : 500 nS

RF level :

0.46 - 0.66 Vp-p

When observing the eye pattern, set the oscilloscope for AC range and raise vertical sensitivity.
