1) Before returning an instrument to the customer, Any measurements not within the limits specified
always make a safety check of the entire instrument, herein indicate a potential shock hazard that must
including, but not limited to, the following items: be eliminated before returning the instrument to
the customer.
(1) Be sure that no built-in protective devices are
defective or have been defeated during servicing.
(1)Protective shields are provided to protect both
the technician and the customer. Correctly replace
all missing protective shields, including any
removed for servicing convenience.
(2)When reinstalling the chassis and/or other
assembly in the cabinet, be sure to put back in place
all protective devices, including, but not limited to,
nonmetallic control knobs, insulating fish papers,
adjustment and compartment covers/shields, and
isolation resistor/capacitor networks. Do not operate
this instrument or permit it to be operated without
all protective devices correctly installed and
functioning.

an electrical return path to the chassis.
Any current measured must not exceed 0.5mA.

(2) The service precautions are indicated or printed on
the cabinet, chassis or components. When servicing,
follow the printed or indicated service precautions
and service materials.

(3) The components used in the unit have a specified

flame resistance and dielectric strength.
When replacing components, use components
which have the same ratings. Components identified

(1) Immediately before handling any semiconductor

component or semiconductor-equipped assembly,
drain off any electrostatic charge on your body by
touching a known earth ground. Alternatively,
obtain and wear a commercially available
discharging wrist strap device, which should be
removed for potential shock reasons prior to
applying power to the unit under test.

(2) After removing an electrical assembly equipped

with ESD devices, place the assembly on a
conductive surface such as aluminum foil, to
prevent electrostatic
charge buildup or exposure of the assembly.

(3) Use only a grounded-tip soldering iron to solder or

unsolder ESD devices.

(4) Use only an anti-static solder removal devices.

Some solder removal devices not classified as
“anti-static” can generate electrical charges sufficient
to damage ESD devices.

(5) Do not use freon-propelled chemicals. These can

generate electrical charges sufficient to damage
ESD devices.

(6) Do not remove a replacement ESD device from its

protective package until immediately before your
are ready to install it.(Most replacement ESD
devices are packaged with leads electrically shorted
together by conductive foam, aluminum foil or
comparable conductive materials).

(7) Immediately before removing the protective

materials from the leads of a replacement ESD
device, touch the protective material to the
chassis or circuit assembly into which the device
will be installed.

 Precautions

1-4 Handling the optical pick-up

The laser diode in the optical pick up may suffer elec-

trostatic breakdown because of potential static electric-
ity from clothing and your body.

The following method is recommended.

(1) Place a conductive sheet on the work bench (The
black sheet used for wrapping repair parts.)

(2) Place the set on the conductive sheet so that the

chassis is grounded to the sheet. Fig.1-3
(6) Short the short terminal on the PCB, which is inside
(3) Place your hands on the conductive sheet(This
the Pick-Up ASS’Y, before replacing the Pick-
gives them the same ground as the sheet.)
Up. (The short terminal is shorted when the Pick-
Up Ass’y is being lifted or moved.)
(4) Remove the optical pick up block
(7) After replacing the Pick-up, open the short terminal
(5) Perform work on top of the conductive sheet. Be
on the PCB.
careful not to let your clothes or any other static
sources to touch the unit.

Be sure to put on a wrist strap grounded to the sheet.

Be sure to lay a conductive sheet made of copper
etc. Which is grounded to the table.

1-5 Pick-up disassembly and reassembly

1-5-1 Disassembly 1-5-2 Assembly

1) Remove the power cord. 1) Replace the Pick-up.

2) Disassemble the Deck-Assy. 2) Remove the soldering 2 points on Pick-up.
3) Make solder land 2 points short on Pick-up. 3) Reassemble the Deck-Assy.
(See Fig. 1-4)
4) Disassemble the Pick-up.

Note : If the assembly and disassembly are not done in correct sequence, the Pick-up may be damaged.
