SECTION 1 SERVICE NOTE
This Compact Disc player is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT label is located on the bottom exterior. CAUTION Use of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous radiation exposure. 1-1. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic 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. 1-2. 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 objectivelens. 1-3. 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. 1-4. 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. 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.

ZS-M30

1-5. CHUCK PLATE JIG ON REPAIRING On repairing CD section, playing a disc without the CD lid, use Chuck Plate Jig. · Code number of Chuck Plate Jig: X-4918-255-1

1-6. CHECKING THE LASER DIODE AND FOCUS SEARCH OPERATION 1. Turn on the POWER and open the CD cover. 2. As shown below, push S701 (CD DOOR) with a screwdriver or other tool. 3. Press the CD button. 4. Check the objective lens to make sure that the laser diode is emitting light. If not so, the auto power control circuit or optical pickup would be damaged. Verify that the objective lens moves vertically three times for focus search.

Insert a precision screw driver and push SWITCH (S701)

When using test disc (MDW-74/AU-1) C1 error : Below 80 ADER : Below 2 b. When using check disc (TDYS-1) C1 error : Below 50

· Clean the optical pick-up · Adjust again · Replace the optical pick-up · Replace the optical pick-up

· Replace the optical pick-up

· Replace the optical pick-up

Self-recording/playback · CPLAY error rate check check Specified value: C1 error : Below 80 ADER : Below 2

If always unsatisfactory: · Replace the overwrite head · Check for disconnection of the circuits around the overwrite head If occasionally unsatisfactory: · Check if the overwrite head is distorted · Check the mechanism around the sled

Note: The criteria for determination above is intended merely to determine if satisfactory or not, and does not serve as the specified value for adjustments. When performing adjustments, use the specified values for adjustments.

· For details of each adjustment mode, refer to "5. Electrical Adjustments". · If a different mode has been selected by mistake, press the NO/CANCEL button to release that mode. · EEP MODE is not used for servicing and therefore are not described in detail. If these modes are set accidentally, press the NO/CANCEL button to release the mode immediately. Be especially careful this mode will overwrite the non-volatile memory and reset it, and as a result, the unit will not operate normally. ·When selecting test mode, usually the message "TEMP ADJUST" appears. In two rare cases, however, another message may be shown. 1. After conclusion of automatic temperature compensation (starting from display "TEMP = 00"), the message "Disc Insert" appears. 2. The message "Disc Insert" is displayed right form the start. In both cases press the YES/ENTER button while holding the EDIT button, thus displaying "TEMP ADJUST" and entering normal test mode. In order to cause "TEMP ADJUST" to be displayed whenever test mode is selected, execute the following steps. 1. Rotate the jog dial until "EEP MODE" is shown. 2. Press the YES/ENTER button to display "EEP READ". 3. Press the YES/ENTER button to display "EEP XXXX". (The first two "X"-marks represent the address, the latter two the value). 4. Rotate the jog dial to set the address to 15. 5. Press the YES/ENTER button while holding the EDIT button. 6. Confirm that the display shows "EEP15XX >XX". 7. Rotate the jog dial to set the value after the ">"-mark to FF. 8. Press the YES/ENTER button. 9. Confirm that the display shows "Complete". 10.After that, confirm that the display turns to "EEP READ". 11.Press the YES/ENTER button. 12.Confirm that the display shows "EEP15FF". 13.Press the NO/CANCEL button.

2. PRECAUTIONS FOR CHECKING LASER DIODE EMISSION To check the emission of the laser diode during adjustments, never view directly from the top as this may lose your eye-sight. 3. PRECAUTIONS FOR USE OF OPTICAL PICK-UP (KMS-260B) As the laser diode in the optical pick-up is easily damaged by static electricity, solder the laser tap of the flexible board when using it. Before disconnecting the connector, desolder first. Before connectingthe connector, be careful not to remove the solder. Also take adequate measures to prevent damage by static electricity. Handle the flexible board with care as it breaks easily.

4. Use the following tools and measuring device. · Check Disc (MD) TDYS-1 (Part No. 4-963-646-01) · Test Disc (MDW-74/AU-1) (Part No. 8-892-341-41) · Laser power meter LPM-8001 (Part No. J-2501-046-A) or MD Laser power meter 8010S (Part No. J-2501-145-A) · Oscilloscope (Measure after performing CAL of prove) · Digital voltmeter · Thermometer 5. When observing several signals on the oscilloscope, etc., make sure that VC and ground do not connect inside the oscilloscope. (VC and ground will become short-circuited) 6. Using the above jig enables the waveform to be checked with-out the need to solder. (Refer to Service Note on page 3) 7. As the disc used will affect the adjustment results, make sure that not dusts nor fingerprints are attached to it.
Laser Power Meter

When performing laser power checks and adjustment (electrical adjustment), use of the new MD laser power meter 8010S (Part No. J-2501-145-A) instead of the conventional laser power meter is convenient. It sharply reduces the time and trouble to set the laser power meter sensor onto the objective lens of optical pick-up.
