1.4. Handling the optical pick-up
The laser diode in the optical pick up may suffer electrostatic breakdown because of potential static electricity 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 to let your clothes or any other static sources touch the unit.
NOTE
•
Be sure to put on a wrist strap grounded to the sheet.
•
Be sure to lay a conductive sheet, that is grounded to the table, made of copper.
