9. Cautions to be taken when handling Optical Pickup
The laser diode used inside optical pickup could be destroyed due to static electricity as a
potential difference is caused by electrostatic load discharged from clothes or human body.
Handling the parts carefully to avoid electrostatic destruction during repair.
9.1. Handling Optical Pickup
1. Do not impact on optical pickup as the unit structurally uses an
extremely precise technology.
2. Short-circuit the flexible cable of optical pickup remove from the
circuit board using a short-circuit pin or clip in order to prevent
laser diode from electrostatic destruction (Refer to Fig. 9.1 and
Fig. 9.2)
3. Do not handle flexible cables forcibly as this may cause snapping.
Handle the parts carefully (Refer to Fig. 9.1)
4. A new optical pickup is equipped with an anti-static flexible cable.
After replacing and connecting to the flexible board, cut the anti-
static flexible cable. (Refer to Fig. 9.1)
9.2. Replacing Precautions for Optical Pickup Unit
DVD/CD Optical Pickup
The optical pickup by which part supply was carried out attaches the short clip to the flexible
