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. 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 emis- sion, observe from more than 30 cm away from the objective lens. LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveforms is output three times. 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. Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C dur- ing 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. This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior. Laser component in this product is capable of emitting radiation exceeding the limit for Class 1. The following caution label is located inside the unit. 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.

WRITING FOCUS/TRACKING AUTO GAIN DATA In general for the CD players that use a digital servo IC, the focus/ tracking gain is automatically adjusted each time a disc is changed. In this set, the gain in test disc (YEDS-18) has been written to a nonvolatile memory (IC803: X24C01S) on the Display Board, and therefore the gain is not readjusted even if a disc is changed. Accordingly, always write auto gain data when replacing the Servo Board, IC803 on Display Board, or optical pick-up. 1)Connect CN805 1 pin (IN/OUT SW) and 6 pin (GND) on Display Board. Under this condition, the set will operate even when the disc lid is open (or Key Board is not connected). 2)Connect TP (ADJ: CN105 3 pin) on Servo Board to GND, and TP (VC: CN108 2 Pin) to TP3 (TEI: IC105 pin) with lead wires respectively. 3)Connect an oscilloscope to TP (TE: CN108 1 pin). 4)Insert the test disc (YEDS-18), turn on POWER switch, and play fifth music with (PLAY) and AMS Keys on the Remocon. 5)Adjust RV101 so that the waveform on oscilloscope is verticolly symmetric with respect to the A Vdc, and also its level is 1.3 0.6 Vp-p. At this time, A/B 100 = 22 (%) or less 6)The auto gain data are written when a lead wire between TP (ADJ: CN105 3 pin) and GND is removed. Note:If the POWER switch was turned on without connecting TP (ADJ) to the GND, auto gain data are not written to the memory even if a disc is inserted, but the previous data saved in the memory are used as focus/tracking data. 1-2. AF MODE With the TP (AFJ: CN105 2 Pin) connected to the GND on Servo Board, turn on the POWER switch, and the AF mode is activated and the following checking can be made. 1-2-1.

ADJ MODE With CN105 3 pin connected to 1 pin on the Servo Board, turn on the POWER switch, and the ADJ mode is activated where the following operation is executed. GFS, even if low continuously during playing, will cause noth- ing. High speed servo is disabled during an access. Gain of focus servo and spindle servo is not lowered. Manual operation and measurement for servo system are en- abled. (For detailed operation method, see the button function table in ADJ mode.) 1-4. CLV-S MODE Connect TP1(ADJ) to the GND after turning on the POWER switch, and the spindle servo becomes CLV-S mode during play- ing.
