SERVICE PROCEDURES

1. S afety~check out
After correcting the original service problem,perform
the following safety check before releasing the set
to the customer:
Connect the insulating-resistance tester between the
plug of power supply cord and chassis.
SpecificationszMore than lOMohm at 500V.

2. Voltage Selector (B ack panel)
Worldwide models are equipped with a voltage selector
to conform with local power supplies.Be sure to set
this switch to match the voltage of the power supply
in user's area before turning the power switch on.
Voltage is changed by sliding the groove in the switch
with a screw driver to the right or left.
Confirm that the switch has been moved all the way to
the right or left before turning the power switch on.

CAUTION ON REPLACEMENT OF OPTICAL PICKUP

The laser diode in the optical pickup block is so
sensitive to static electricitysurge current and etc.

During repair,carefulley take the following precautions.
(The following precautions are included in the service

that the components are liable to be broken down parts.)

l.Ground for the work-desk. 3.Grounding for the human body.
Place a conductive sheet such as a sheet of copper Be sure to put on a wrist-strap for grounding whose

desk and place the set on the conductive sheet so
that the chassis.

2.Grounding for the test equipment and tools.
Test equipments and toolings should be grounded
in order that their ground level is the same the
ground of the power source.

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.
