Precautions
1. Precautions
Follow these safety, servicing and ESD precautions to prevent damage and to protect against
potential hazards such as electrical shock.
1-1 Safety Precautions
1-1-1 Warnings
1. For continued safety, do not attempt to modify the circuit board.
2. Disconnect the AC power Jack before servicing.
1-1-2 Servicing the LCD Monitor
1. When servicing the LCD Monitor Disconnect the AC line cord from the AC outlet.
2. It is essential that service technicians have an accurate voltage meter available at all times.
Check the calibration of this meter periodically.
1-1-3 Fire and Shock Hazard
Before returning the monitor to the user,perform the following safety checks :
1. Inspect each lead dress to make certain that the leads are not pinched or that hardware is not
lodged between the chassis and other metal parts in the monitor.
2. Inspect all protective devices such as nonmetallic control knobs, insulating materials, cabinet
backs, adjustment and compartment covers or shields, isolation resistor-capacitor networks,
mechanical insulators, etc.
3. To be sure that no shock hazard exists, check for leakage current in the following manner.
Warning : Do not use an isolation transformer during this test.
a. Plug the AC line cord directly into a 120 Volt AC outlet.
b. Unisg two clip leads, connect 1.5 , 10 watt resistor paralleled by a 0.15 capacitor in series
with an exposed metal cabinet part and a known earth ground, such as an electrical conduit or
electrical ground connected to an earth ground.

111707 Service Manual
PRECAUTION
Precautions
c. Use a SSVM or VOM with 1000 ohms per-volt or higher sensitivity to measure the AC voltage
drop across the resistor (see Figure 1-1).
d. Connect the resistor to an exposed metal part having a return path to the chassis(metal cabinet,
screw heads, knobs, shafts, escutcheon, etc.) and measure the AC voltage drop across the
resistor.
e. Any reading of 5.25 Volt RMS ( this corresponds to 3.5 milliampere AC ) or more is excessive
and indicates a potential shock hazard. Correct the shock hazard before returning the monitor to
the user.
1-1-4 Product Safety Notices
Some electrical and mechanical parts have special safety-related characteristics which are often not
evident from visual inspection. The protection they give may not be obtained by replacement that
does not have the same safety characteristics as the recommended replacement part may create
shock, fire and /or other hazards. Product safety is under review continuously and new instructions
are issued whenever appropriate.

Precautions
1-2 Servicing Precautions
WARNING : An electrolytic capacitor installed with the wrong polarity might explode.
Caution : Before servicing instruments covered by this service manual and its supplements,
read and follow the Safety Precautions section of this manual.
Note : If unforeseen circumstances create conflict between the following servicing preautions
and any of the safety precautions, always follow the safety precautions.
1-2-1. General Servicing Precautions
1. Servicing precautions are printed on the cabinet, and should be followed closely.
2. Always unplug the unit's AC power cord from the AC power source before attempting to :
(a) remove or reinstall any component or assembly, (b) disconnect PCB plugs or connectors,
(c) connect a test component in paralled with an electrolytic capacitor.
3. 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.
4. After servicing, always check that the screws, components and wiring have been correctly
reinstalled. Make sure that the portion around the serviced part has not been damaged.
5. Check the insulation between the blades of the AC plug and accessible conductive parts
(examples; metal panels, input terminals and earphone jacks)
6. Insulation Checking Procedure : Disconnect the power cord from the AC source and turn the power
switch ON. Connect an insulation resistance meter(500V) to the blades of the AC plug.
The insulation resistance between each blade of the AC plug and accessible conductive parts
(see above) should be greater than 1 megohm.
7. 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.

PRECAUTIONS
Precautions
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.
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.
4. Use only a ground-tip soldering iron to solder ESDs.
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.
6. Do not remove a replacement ESD from its protective package until you are ready to install it. Most
relacement ESDs are packaged with leads that are electrically shorted together by conductive
foam, aluminum foid 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.
Caution : Be sure no power is applied to the chassis or circuit and observe all other safety
precautions.
8. Minimize body motions when handling unpackaged replacement ESDs. Motions such as brushing
clothes together, or lifting your font from a carpeted floor can generate enough static electricity to
damage an ESD.
