CAUTION OF REPLACEMENT OF PICKUP UNIT
Remove the 2 screws (37) and remove the
front panel L (73) and front panel R(74)
form front bracket.
Remove the 4 screws (65) of the place which is
fixing the door assy (63) and the slider assy(M28).
Remove the door assy (63) from the front part.

Remove the 8 screws (M2) and remove the
CD mechenism part from the front part.
The laser diode in the optical pickup block is so sensitive to
static electricity, surge current and etc., that the components
are liable to be broken down or its reliability remarkably
deteriorated.
During repair, carefully take the following precautions.
(The following precautions are included in the service
parts.)
PRECAUTIONS
1. Ground for the work-desk.
Place a conductive sheet such as a sheet of copper
(with impedance lower than 10Mohm) on the work-
desk and place the set on the conductive sheet so that
the chassis can be grounded.
2. Grounding for the test equipments and tools.
Test equipments and toolings should be grounded in
order that their ground level is the same the ground of
the power source.
3. Grounding for the human body.
Be sure to put on a wrist-strap for grounding whose
other end is grounded.
Be particularly careful when the workers wear
synthetic fiber clothes, or air is dry.
4. Select a soldering iron that permits no leakage and
have the tip of the iron well-grounded.
5. Do not check the laser diode terminals with the
probe of a circuit tester or oscilloscope.
