3. Operating Instructions 4. Handling Precautions for MD Mechanism (Optical pickup) The laser diode in the MD mechanism (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body. So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup). 4.1.

Fig. 2 4.2. Grounding for electrostatic breakdown prevention 1. Human body grounding Use the anti-static wrist strap to discharge the static electricity from your body. (as shown in Fig. 3 2. Work table grounding Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is placed, and ground the sheet.
Fig. 4 5. Operation Checks and Component Replacement Procedures - This section describes procedures for checking the operation of the major printed circuit boards and replacing the main components. - For reassembly after operation checks or replacement, reverse the respective procedures. Special reassembly procedures are described only when required.

8. Precaution for Replacement of EEPROM IC (IC202) and SYSTEMCONTROL IC (IC201) 8.1. Replacement of EEPROM IC (IC202) In case of replacing EEPROM IC (IC202), depending on the Parts No. of SYSTEMCONTROL (IC201), it is need to replace SYSTEMCONTROL simultaneously. For details, please refer to the following table.
After replacing P.C.B. ASS’Y, please be sure to perform the “laser power adjustment”, “Off-set automatic adjustment” and “Playback only disc/magneto-optical disc automatic adjustment”.(Refer to “6 Measurements and Adjustments ”) If the set is operated without adjusting, an error will be displayed and the set will not operate. 10.
Secondary trouble can be prevented by taking care during repair. Cover the parts boxes made of plastics with aluminum foil. Ground the soldering iron. Put a conductive mat on the work table. Do not touch the legs of IC or LSI with the fingers directly. Voltage and signal line : Positive voltage line : Playback signal line...
