Preventive measure for laser diode from

When replacing the MONO P.C.B. or DVD
mechanism, solder between lands of the optical
pick up P.C.B. to protect the laser diode against
electrostatic breakdown.
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.
