Cautions to be taken when replacing the optical
pickup
The optical pickup may become damaged due to static
electricity from the human body. Take proper protection
measures against static electricity before repairing the
parts around the optical pickup. (See the page describing
the PREVENTION OF ELECTRO STATIC DISCHARGE.)
1. Do not touch the areas around the laser diode and
actuator.
2. Do not judge the laser diode with a tester. (The tester
will damage the diode.)
3. It is recommended to use an anti-static soldering
iron for soldering or desoldering on the pickup.
(Recommended soldering iron) HAKKO ESD Product
4. Solder the land of the flexible cable in the optical
pickup.
Note:
• When using a soldering iron which is not anti-static,
short-circuit the terminal face of the flexible cable
with a clip. After that, short-circuit the land.
• After the repairing work is completed, remove the
solder according to the correct procedure shown in
this service manual.
