The laser diode in the optical pick-up bloc k may suffer
electrostatic breakdown because of the potential difference
generated by the charged electrostatic load, etc. on clothing and
the human body.
During repair, pay attention to electrostatic breakdown and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.

The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.

Carry out the “S curve check” in “CD section adjustment” and
check that the S curve waveform is output two times.
