Design and specifications are subject to change without notice.
Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270C 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. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
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.
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 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.
When repairing this device with the power on, if you remove the MAIN board or open the upper panel assy, this device stops working. In this case, you can work without the device stopping by fastening the hook of the open/close detect switch (S804).

12. If NG, set the manual mode. Perform automatic adjustment for the items not accepted. (See page 13) 13. To clear the data in overall adjustment mode, set the manual mode and change the mode number 021 (Res NV) to reset the NV. (See page 13) 14. When both CD and MO overall adjustments are OK, set the mode No. 043 (Resume) and clear the clock data.
Check Method : 1. Select the manual mode of test mode, and set the laser power adjusting mode. (mode number 010) 2. Press the. key continuously until the optical pick-up moves to the most inward track. 3. Open the cover and set the laser power meter on the objective lens of the optical pick-up. 4. Press the N key, and set the laser MO read adjustment mode. (mode number 011) 5. Check that the laser power meter reading is 0.81 0.08 mW. 6. Check that the voltage both ends of resitor R501 at this time is below 44 mV. 7. Press the N key, and set the laser CD read adjustment mode. (mode number 012) 8. Check that the laser power meter reading is 0.97 0.10 mW. 9. Check that the voltage both ends of resitor R501 at this time is below 44 mV. 10. Press the N key, and set the laser MO write adjustment mode. (mode number 013) 11. Check that the laser power meter reading is 4.95 0.50 mW. 12. Check that the voltage both ends of resister R501 at this time is below 80 mV. 13. Press the x key. 14. Release the test mode.

SECTION 7 EXPLODED VIEWS
The mechanical parts with no reference number in the exploded views are not supplied. Hardware (# mark) list are given in the last of this parts list. The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified.
NOTE : -XX, -X mean standardized parts, so they may have some difference from the original one. Items marked * are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these items.
