The flexible cable of the optical pickup unit which was supplied as a component is equipped
with a short clip to prevent the laser diode from being damaged due to electrostatic discharge.
Remove the short clip before connecting the flexible cable and make sure that the short land is
open. (If the flexible cable is short-circuited, remove the solder.)
11.3. Grounding for electrostatic breakdown prevention
Some devices such as the DVD player use the optical pickup (laser diode) and the optical
pickup will be damaged by static electricity in the working environment. Proceed servicing
works under the working environment where grounding works is completed.
11.3.1. Worktable grounding
1. Put a conductive material (sheet) or iron sheet on the area where
the optical pickup is placed, and ground the sheet.
11.3.2. Human body grounding
1. Use the anti-static wrist strap to discharge the static electricity
form your body.
