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.

4. Solder the land of the flexible cable in the optical pickup.

Note:

When using a soldering iron which is not

destaticized, short-circuit the terminal face of the

flexible case 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 Technical Guide.
