1-4 Handling the optical pick-up
The laser diode in the optical pick up may suffer elec-
trostatic breakdown because of potential static electric-
ity from clothing and your body.
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(This
gives them the same ground as the sheet.)
(4) Remove the optical pick up 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.
u
Be sure to put on a wrist strap grounded to the
sheet.
u
Be sure to lay a conductive sheet made of copper
etc. Which is grounded to the table.
(6) Short the short terminal on the PCB, which is inside
the Pick-Up ASS’Y, before replacing the Pick-
Up. (The short terminal is shorted when the Pick-
Up Ass’y is being lifted or moved.)
(7) After replacing the Pick-up, open the short terminal
on the PCB.
