1. Precautions and Safety Notices

1. Caution :

No modification of any circuit should be attempted . Service work should only be performed after you are thoroughly
familiar with all of the following safety checks and servicing guide line

2. Safety Check :

Care should be taken while servicing this LCD display. Because of the high voltage used in the inverter circuit. These
voltage are exposed in such areas as the associated transformer circuits .

3. POWER SUPPLY REQUIREMENTS
The external power converter for this display utilizes AC and DC cords , AC cord is detachable , but DC cord is

permanently attached . Any attempt to replace another adapter could result in serious problem on the display .

4. LEAKAGE CURRENT HOT CHECK
4-1 Plug the AC cord directly into the AC outlet. Do not use an isolation transformer during this check.
4-2 Connect a 1500 ohm , 10 watt resistor , paralleled by a 0.15uF capacitor between each metallic part and a good earth

ground

4-3 Use an AC voltmeter with 1000 ohm / volt or more sensitivity and measure the AC voltage across the combination

1500 ohm resistor and 0.15uF capacitor.
4-4 Move the resistor connection to each exposed metallic part and measure the voltage.
4-5 Reverse the polarity of the AC plug in the AC outlet and repeat the above measurement.
4-6 Voltage measured must not exceed 1.5 volt RMS, from any exposed metallic part to the ground. A leakage current

tester may be used in the above hot check, in which case any circuit measured must not exceed 1.0 milliamp. In the

case of a measurement exceeding the 1.0 milliamp value, a rework is required to eliminate the chance of a shock

hazard .

Handing and placing method

Correct methods : Incorrect Methods :

Only touch the metal-frame of the panel or the front
cover of the monitor .
Do not touch the surface of the polarizer .

Surface of the panel is pressed by fingers & this may
cause “ MURA “

Take out the monitor with cushion Take out the monitor by grasping the LCD panel.

That may cause “ MURA“.

Place the monitor on a clean & soft foam pad . Place the monitor on foreign objects .

That could scratch the surface of panel

Main Menu Controls

Adjust the menu items shown below by using the up and down buttons.
A. Auto Image Adjust automatically sizes, centers, and fine tunes the video signal to eliminate waviness and distortion.

Press the [2] button to obtain a sharper image.

NOTE: Auto Image Adjust works with most common video cards. If this function does not work on your LCD display,
then lower the video refresh rate to 60 Hz and set the resolution to its pre-set value.

B. Contrast adjusts the difference between the image background (black level) and the foreground (white level).
C. Brightness adjusts the lamps current to control the screen brightness.
D. Color Adjust provides several color options: preset color temperatures and Custom User Color which allows you to adjust

red (R), green (G), and blue (B). The factory setting for this product is 6500K (6500° Kelvin).

9300K — Adds blue to the screen image for cooler white (used in most office settings with fluorescent lighting).
5400K — Adds red to the screen image for warmer white and richer red.
Custom User Color — Individual adjustments for red, green, and blue.
1 To select color (R, G or B) press button [2].

2 To adjust selected color, press or .

3 When you are finished making all color adjustments, press button [1] twice.

E. Information displays the timing mode (video signal input) coming from the graphics card in your computer. See your

graphic card’s user guide for instructions on changing the resolution and refresh rate (vertical frequency). VESA 1280 x
1024 @ 60 Hz (recommended) means that the resolution is 1280 x 1024 and the refresh rate is 60 Hertz.

F. Manual Image Adjust controls are explained below:
H. Size (Horizontal Size) adjusts the width of the screen image.
NOTE: Vertical size is automatic with your LCD display.
H./V. Position adjusts horizontal and vertical position of the screen image. You can toggle between Horizontal and

Vertical by pressing button [2]. Horizontal moves the screen image to the left or to the right. Vertical moves the screen image
up and down.

Fine Tune sharpens focus by aligning the illuminated text and/or graphic characters.
Sharpness adjusts the clarity and focus of the screen image.
Setup Menu controls are explained below:
Language allows you to choose the language used in the menus and control screens.
Resolution Notice displays the recommended resolution for this LCD display.
Enable allows the Resolution Notice to appear on-screen.
Disable will not allow the Resolution Notice to appear on-screen.
OSD Timeout sets the length of time an on-screen display screen is displayed. For example, with a“15 second”

setting, if a control is not pushed within 15 seconds, the display OSD disappears.

G. OSD Position allows you to move the on-screen display menus and control screens.
H. Memory Recall returns adjustments to the original factory settings if the display is operating in a factory Preset Timing

Mode listed in this user guide.
