14-1

14 Reference Infomation

- Dot Pitch

- External Device Input

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

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.

- 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.

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:

Figure 1-1. Leakage Current Test Circuit

1. Inspect each lead dress to make certain that the leads are

4. With the unit completely reassembled, plug the AC line

not pinched or that hardware is not lodged between the

cord directly into a 120V AC outlet. With the unit’s AC

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.

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

3. Leakage Current Hot Check (Figure 1-1):

repeat the test.

WARNING : Do not use an isolation

transformer during this test.

1-1-4 Product Safety Notices

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).

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

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. 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).

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.

(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.

The insulation resistance between each blade of the AC

plug and accessible conductive parts (see above) should

be greater than 1 megohm.

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.

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 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.

1 Precautions

1-4 Installation Precautions

1. For safety reasons, more than two people are

required for carrying the product.

6. Keep the antenna far away from any high-voltage

cables and install it firmly. Contact with the highvoltage

cable or the antenna falling over may

cause fire or electric shock.

2. Keep the power cord away from any heat emitting

devices, as a melted covering may cause fire or

electric shock.

7. When installing the product, leave enough space

(10cm) between the product and the wall for

ventilation purposes.

3. Do not place the product in areas with poor

ventilation such as a bookshelf or closet. The

increased internal temperature may cause fire.

A rise in temperature within the product may

cause fire.

4. Bend the external antenna cable when connecting

it to the product. This is a measure to protect it

from being exposed to moisture. Otherwise, it

may cause a fire or electric shock.

5. Make sure to turn the power off and unplug the

power cord from the outlet before repositioning

the product. Also check the antenna cable or the

external connectors if they are fully unplugged.

Damage to the cord may cause fire or electric

shock.
