— SERVICING NOTE —
NOTES ON LASER DIODE EMISSION CHECK
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.
LASER DIODE CHECK
1. Ground servo amp board TP12 (IC102 pin
(LD ON)).
2. Observe the objective lens and confirm that the
laser diode is emitting light.
