14 Reference Infomation
- Dot Pitch
The image on a monitor is composed of red, green
and blue dots. The closer the dots, the higher the
resolution. The distance between two dots of the
same color is called the 'Dot Pitch'. Unit: mm
- Vertical Frequency
The screen must be redrawn several times per
second in order to create and display an image for
the user. The frequency of this repetition per
second is called Vertical Frequency or Refresh
Rate. Unit: Hz
Example: If the same light repeats itself 60 times
per second, this is regarded as 60 Hz.
- Horizontal Frequency
The time to scan one line connecting the right
edge to the left edge of the screen horizontally is
called Horizontal Cycle. The inverse number of the
Horizontal Cycle is called Horizontal Frequency.
Unit: kHz
- Interlace and Non-Interlace Methods
Showing the horizontal lines of the screen from the
top to the bottom in order is called the
Non-Interlace method while showing odd lines and
then even lines in turn is called the Interlace
method. The Non-Interlace method is used for the
majority of monitors to ensure a clear image. The
Interlace method is the same as that used in TVs.
- Plug & Play
This is a function that provides the best quality
screen for the user by allowing the computer and
the monitor to exchange information automatically.
This monitor follows the international standard
VESA DDC for the Plug & Play function.
- Resolution
The number of horizontal and vertical dots used to
compose the screen image is called 'resolution'.
This number shows the accuracy of the display.
High resolution is good for performing multiple
tasks as more image information can be shown on
the screen.
Example: If the resolution is 1280 x 1024 , this
means the screen is composed of 1280 horizontal
dots (horizontal resolution) and 1024 vertical lines
(vertical resolution).
- S-Video
Short for "Super Video." S-Video allows up to 800 lines
of horizontal resolution, enabling high-quality video.
14-2
- External Device Input
External device input refers to video input from
such external video devices as VCRs, camcorders
and DVD players, separate from a TV broadcast.
- DVD
A type of digital disk technology that takes up only
the benefits of CD and LD, to implement a high
resolution/quality, which enables the user to enjoy
clearer images.

1 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 and DC 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 resistorcapacitor networks, mechanical insulators, etc.
3.
Leakage Current Hot Check (Figure 1-1):
WARNING : Do not use an isolation
transformer during this test.
Use a leakage current tester or a metering system that
complies with American National Standards Institute
(ANSI C101.1, Leakage Current for Appliances), and
Underwriters Laboratories (UL Publication UL1410,
59.7).
Figure 1-1. Leakage Current Test Circuit
4.
With the unit completely reassembled, plug the AC line
cord directly into a 120V AC outlet. With the unit’s AC
switch first in the ON position and then OFF, measure
the current between a known earth ground (metal water
pipe, conduit, etc.) and all exposed metal parts,
including: metal cabinets, screwheads and control shafts.
The current measured should not exceed 0.5 milliamp.
Reverse the power-plug prongs in the AC outlet and
repeat the test.
1-1-4 Product Safety Notices
Some electrical and mechanical parts have special safetyrelated characteristics which are often not evident from visual
inspection. The protection they give may not be obtained by
replacing them with components rated for higher voltage,
wattage, etc. Parts that have special safety characteristics are
identified by
on schematics and parts lists. A substitute
replacement that does not have the same safety characteristics
as the recommended replacement part might create shock, fire
and/or other hazards. Product safety is under review
continuously and new instructions are issued whenever
appropriate.
1-1
1 Precautions
1-2 Servicing Precautions
WARNING:
An electrolytic capacitor installed with the wrong polarity might explode.
Caution:
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.
2.
3.
Always unplug the unit’s AC power cord from the AC
power source and disconnect the DC Power Jack before
attempting to:
(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.
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.
Check the insulation between the blades of the AC plug
and accessible conductive parts (examples: metal panels,
input terminals and earphone jacks).
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.
The insulation resistance between each blade of the AC
plug and accessible conductive parts (see above) should
be greater than 1 megohm.
6.
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.
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.
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 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 grounded-tip soldering iron to solder or
desolder 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
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.
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 foot from a carpeted floor can
generate enough static electricity to damage an ESD.
