Cautions to be taken when replacing the optical pickup
The optical pickup may break down due to the static
electricity of human body. Take proper protection measures
against static electricity before repairing the parts around
the
optical pickup. (See the page describing the
PREVENTION OF STATIC ELECTRICITY 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 be damaged easily.)
3. It is recommended to use a destaticized soldering iron
for short-circuiting or removing the laser diode.
