between lands of the optical pick up P.C.B. to protect the laser diode
against electrostatic breakdown. b. Move the slider in the direction indicated with a screw driver until the tray is ejected.
c. Gently pull the tray out.
Preventive measure for laser diode
from electrostatic breakdown Cable connections
Notes
• Use an anti-static soldering iron to short-circuit and unshort-
circuit laser diode.
• After you have finished repairing, remove the solder from the
short-circuit location.
