3. Replacing the Main Parts of the Traverse Unit
This section describes the replacement of the main parts in
the Traverse Unit, including the Laser Pick-Up, the Disc Motor,
the Traverse Motor Unit.
Work should be performed after removing the Traverse Unit.
To Prevent Damage to the Laser Diode
Static electricity destroys the Laser Diode. Always
take countermeasures to prevent static electricity
damage when performing repairs around the Laser
Pick-Up.
1. Do not touch the area around the Laser Pick-Up
or the Actuator.
2. Do not check the Laser Diode with a tester or other
device (the Laser Diode can be broken quite
easily).
3. Short-Circuit the Laser Pick-Up
Solder the Land in the center of the flexible cable
of the Laser Pick-Up. This will short-circuit the
Laser Diode and help prevent damage from static
electricity.
Caution:
Do not forget to remove the soldered Laser Diode
short-circuit after finishing repair, and leave the
circuit open.
