The laser diode in the traverse unit (optical pickup) may be damaged due to static electricity from clothes or the human
body. Use caution to prevent electrostatic damage when servicing or handling the laser diode.
1. Grounding for electrostatic damage prevention
1. Worktable grounding
Put a grounded conductive material (sheet) or iron sheet on the area where the optical pickup is placed.
2. Human body grounding
Use an anti-static wrist strap to discharge the static electricity from your body.
2. Handling of the optical pickup
1. To prevent damage to the optical pickup replacement parts during transportation and before installation, both ends
of the laser diode are short-circuited. After installing the new part, remove the short circuit according to the correct
procedure in this service manual.
2. Do not use a tester to check the laser diode in the optical pickup. The power supply in the tester will damage the
laser diode.
3. Handling Precautions for the Traverse Unit (Optical Pickup)
1. Handle the traverse unit (optical pickup) gently, as it is an extremely high-precision assembly.
2. The flexible cable lines may break if an excessive force is applied to it. Use caution when handling the cable.
3. The semi-fixed resistor for laser power adjustment should not be adjusted. Do not turn the resistor.
