1 Precautions

1-2 Servicing Precautions

WARNING:

Caution:

An electrolytic capacitor installed w ith the w rong polarity m ight explode.

Before servicing units covered by this service manual, read and follow the Safety Precautions

section of this manual.

Note:

If unforeseen circumstances create conflict between the following servicing precautions and any of the

safety precautions, always follow the safety precautions.

1-2-1 General Servicing Precautions

1. Always unplug the unit’s AC power cord from the

AC power source and disconnect the DC Power

Jack before attempting to:

4. Check the insulation between the blades of the AC

plug and accessible conductive parts (examples:

metal panels, input terminals and earphone jacks).

(a) remove or reinstall any component or assembly,

(b) disconnect PCB plugs or connectors, (c) connect

a test component in parallel with an electrolytic

capacitor.

5. Insulation Checking Procedure: Disconnect the

power cord from the AC source and turn the power

switch ON. Connect an insulation resistance meter

(500 V) to the blades of the AC plug.

2. Some components are raised above the printed

circuit board for safety. An insulation tube or tape

is sometimes used. The internal wiring is

sometimes clamped to prevent contact with

thermally hot components. Reinstall all such

elements to their original position.

The insulation resistance between each blade of the

AC plug and accessible conductive parts (see

above) should be greater than 1 megohm.

6. Always connect a test instrument’s ground lead to

the instrument chassis ground before connecting

the positive lead; always remove the instrument’s

ground lead last.

3. After servicing, always check that the screws,

components and wiring have been correctly

reinstalled. Make sure that the area around the

serviced part has not been damaged.

1-3 Electrostatically Sensitive Devices (ESD) Precautions

Some semiconductor (solid state) devices can be easily damaged by static electricity. Such components are commonly

called Electrostatically Sensitive Devices (ESD). Examples of typical ESD devices are integrated circuits and some field-

effect transistors. The following techniques will reduce the incidence of component damage caused by static electricity.

1. Immediately before handling any semiconductor

components or assemblies, drain the electrostatic

charge from your body by touching a known earth

ground. Alternatively, wear a discharging wrist-

strap device. To avoid a shock hazard, be sure to

remove the wrist strap before applying power to

the monitor.

6. Do not remove a replacement ESD from its

protective package until you are ready to install it.

Most replacement ESDs are packaged with leads

that are electrically shorted together by conductive

foam, aluminum foil or other conductive materials.

7. Immediately before removing the protective

material from the leads of a replacement ESD,

touch the protective material to the chassis or

circuit assembly into which the device will be

installed.

2. After removing an ESD-equipped assembly, place it

on a conductive surface such as aluminum foil to

prevent accumulation of an electrostatic charge.

3. Do not use freon-propelled chemicals. These can

generate electrical charges sufficient to damage

ESDs.

Caution: Be sure no power is applied to the

chassis or circuit and observe all

other safety precautions.

4. Use only a grounded-tip soldering iron to solder or

desolder ESDs.

8. Minimize body motions when handling

unpackaged replacement ESDs. Motions such as

brushing clothes together, or lifting your foot from

a carpeted floor can generate enough static

electricity to damage an ESD.

5. Use only an anti-static solder removal device. Some

solder removal devices not classified as “anti-static”

can generate electrical charges sufficient to damage

ESDs.
