ADJUSTMENT PROCEDURES
Handling the optical pickup
The laser diode used in the optical pickup may break
down due to potential differences caused by electricity
produced by clothing or the human body, care should
therefore be taken to prevent electrostatic discharge
whilst repairing the optical pickup.
The following method is recommended.
(1) Place a conductive sheet on the work bench (The
black sheet used for wrapping repair parts.)
(2) Place the set on the conductive sheet so that the
chassis is grounded to the sheet.
(3) Place your hands on the conductive sheet (doing
this gives them the same ground as the sheet.)
(4) Remove the optical pickup block
(5) Perform work on top of the conductive sheet. Be
careful not to let your clothes or any other static
sources to touch the unit.
* Grounding the Human Body, use an antistatic wrist
strap to discharge static electricity from your body.
* Grounding the work place, use either an antistatic
matt or a sheet of steel on the area where the optical
pickup is to be placed and ground the matt/sheet.
(6) Short the short terminal on the PCB, which is in-side
the Pickup Assembly, before replacing the Pickup.
(The short terminal is shorted when the Pickup
Assembly is being lifted or moved.)
A
(7) After replacing the Pickup, open the short terminal
on the PCB.
