2. To prevent the laser diode from the electrostatic discharge
damage, the flexible cable of the optical pickup unit removed
should be short-circuited with a short pin or a clip.
3. The flexible cable may be cut off if an excessive force is applied to
it. Use caution when handling the flexible cable.
4. The antistatic FPC is connected to the new optical pickup unit.
After replacing the optical pickup unit and connecting the flexible
cable, cut off the antistatic FPC.
6.2. Grounding for electrostatic breakdown prevention
Some devices such as the DVD player use the optical pickup (laser diode) and the optical
pickup will be damaged by static electricity in the working environment. Proceed servicing
works under the working environment where grounding works is completed.
