Dismantling and assembling the CD mechanism assembly
1. Notice regarding replacement of optical pickup
Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged,
can destroy the laser diode in the traverse unit (optical pickup). Take care to prevent this when performing
repairs to the optical pickup or connected devices.
(Refer to the section regarding anti-static measures.)
1. Do not touch the area around the laser diode and actuator.
2. Do not check the laser diode using a tester, as the diode may easily be destroyed.
3. It is recommended that you use a grounded soldering iron when shorting or removing the laser diode.
Recommended soldering iron: HAKKO ESD-compatible product
4. Solder the short-circuit land on the optical pickup unit.
* In accordance with the following steps, solder the short-circuit land properly.
1. Remove the four screws attaching the micon board as shown in Fig1.
(Refer to "Disassembly method", page 2-8.)
2. Raise the micon board as shown in Fig. 2.
3. Prior to disconnecting the card wire from the connector CN601 on the micon board, solder the
short-circuit land on the pickup unit.
4. When reassembling, unsolder the short-circuit land on the pickup unit after connecting the card wire.
