When removing the Laser pick-up or the Servo PCB, the Laser pickup PCB must be provided with a protective soldered joint before unplugging the connectors to avoid damage to the Laser diodes by static charges.
When inserting the new Laser pick-up (CD drive mechanism) the soldered joint fitted at the factory must be removed after the connectors are plugged in.
