10、RVICING 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

11、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 refle

12、ctive 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. LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the “S curve check” in “CD section adjustment” and check that the S c

13、urve waveform is output two times. HOW TO OPEN THE DISC TRAY WHEN POWER SWITCH TURNS OFF Insert a tapering driver into the aperture of the unit bottom, and turn in the direction of arrow. *To close the disc table, turn the driver in the reverse direction.

Therefore, check each item in order given. 2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated. 3. Use an oscilloscope with more than

27、 10M impedance. 4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks. S Curve Check Procedure : 1. Connect oscilloscope to test point TP (FE) on BD board. 2. Connect between test point TP (FEI) and TP (VC) by lea

28、d wire. 3. Turn Power switch on. 4. Put disc (YEDS-18) in and turn Power switch on again and ac- tuate the focus search. (actuate the focus search when disc table is moving in and out.) 5.
