The laser diode in the optical pick-up block may suffer electro-
static break-down because of the potential difference generated by
the charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.

NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc refl ective surface by the objective lens in the optical
pickup block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.

: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 °C higher
• Unleaded solder melts at a temperature about 40 °C higher
than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!
•
Strong viscosity
Unleaded solder is more viscous (sticky, less prone to fl ow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.

• When the optical device (KEM-460AAA) is replaced (The
MB-134 board doesn’t replace).
• When both the optical device (KEM-460AAA) and MB-134

“3. Optical device (KEM-460AAA) replacement” other than
the replacement of new optical device).

Note: The servo adjustment is done while writing the OP data. The manual
adjustment is unnecessary.

Do not touch any optical block parts, turn table and during replac-
ing. BD laser diode is very sensitive.
1. Preparation
1-1. ESD Countermeasure
It is necessary to confi rm the state of static electricity in the work
space before the repair is started.
The static electricity resistance of the BD laser is weaker than that
of the DVD/CD laser.
Do work space and worker’s ESD countermeasures to prevent de-
struction by ESD.
