PRECAUTION WHEN INSTALLING A NEW OP
UNIT/PRECAUTION BEFORE UNSOLDERING THE STATIC ELECTRICITY PREVENTION SOLDER
BRIDGE
When installing a new OP unit, be sure to connect the flexible
printed circuit board first of all before removing the static electricity
prevention solder bridge by unsoldering.
Remove the static electricity prevention solder bridge by unsoldering
after the flexible printed circuit board has already been connected. (Do not remove nor unsolder the solder bridge
as long as the OP unit is kept standalone.)
DISC LOADING MECHANISM
The laser diode in the optical pick-up block may suffer
electrostatic 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. 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 pickup block. Therefore, when checking the
laser diode emission, observe from more than 30 cm away from the objective
lens.
