1. Precautions and Safety Notices

1. Appropriate Operation

(1) Turn off the product before cleaning.
(2) Use only a dry soft cloth when cleaning the LCD panel surface.
(3) Use a soft cloth soaked with mild detergent to clean the display housing.
(4) Use only high quality and safety approved AC/DC power cord.
(5) Disconnect the power plug from AC outlet if the product is not used for a long period of time.
(6) If smoke, abnormal noise, or strange odor is present, immediately switch the LCD display off.
(7) Do not touch the LCD panel surface with sharp or hard objects.
(8) Do not place heavy objects on the LCD display, video cable, or power cord.
(9) Do not use abrasive cleaners, waxes or solvents for your cleaning.
(10) Do not operate the product under the following conditions:

- Extremely hot, cold or humid environment.

- Areas susceptible to excessive dust and dirt.

- Near any appliance generating a strong magnetic field.

- Place in direct sunlight.

2. 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 guidelines.

3. Safety Check

Care should be taken while servicing this LCD display. Because of the high voltage used in the inverter circuit, the voltage is

exposed in such areas as the associated transformer circuits.

4. LCD Module Handling Precautions

4.1 Handling Precautions

(1) Since front polarizer is easily damaged, pay attention not to scratch it.
(2) Be sure to turn off power supply when inserting or disconnecting from input connector.
(3) Wipe off water drop immediately. Long contact with water may cause discoloration or spots.
(4) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
(5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface.
(6) Since CMOS LSI is used in this module, take care of static electricity and insure human earth when handling.
(7) Do not open nor modify the Module Assembly.
(8) Do not press the reflector sheet at the back of the module to any directions.
(9) In case if a Module has to be put back into the packing container slot after once it was taken out from the

container, do not press the center of the CCFL Reflector edge. Instead, press at the far ends of the CFL

Reflector edge softly. Otherwise the TFT Module may be damaged.

(10) At the insertion or removal of the Signal Interface Connector, be sure not to rotate nor tilt the Interface

Connector of the TFT Module.

(11) After installation of the TFT Module into an enclosure (LCD monitor housing, for example), do not twist nor

bend the TFT Module even momentary. At designing the enclosure, it should be taken into consideration that

no bending/twisting forces are applied to the TFT Module from outside. Otherwise the TFT Module may be

damaged.

(12) Cold cathode fluorescent lamp in LCD contains a small amount of mercury. Please follow local ordinances or

regulations for disposal.

(13) Small amount of materials having no flammability grade is used in the LCD module. The LCD module should

be supplied by power complied with requirements of Limited Power Source (IEC60950 or UL1950), or be

applied exemption.

(14) The LCD module is designed so that the CFL in it is supplied by Limited Current Circuit (IEC60950 or

UL1950). Do not connect the CFL in Hazardous Voltage Circuit.

• Adjust your computer's graphic card so that it outputs a video signal 1280 x
1024 @ 60 Hz to the LCD display. (Look for instructions on "changing the

4. Circuit Description

4.1 Power supply (DC/DC Converter):

4.1.1 IC251 MP1583 is a switching regulator controller that uses PWM method. That can be used for DC to
DC conversion for step-down. It converts a 12V DC into regulated and stable output voltage of 5V
respectively.

4.1.2 Regulator:
IC253 function is convert a 5V into regulated and stable O/P 3.3V.
IC252,Q255 are a 3.3V convert into O/P2.5V.

4.2 DDC data select:

4.2.1 IC600(AT24C02) is save D-SUB DDC data.

4.2.2 IC602(AT24C02) is save DVI, DDC data.

4.3 FLASH MEMORY

The IC402(A290011TL-70) is 128K X 8 Bit CMOS 5.0 Volt-only Flash Memory for Program save.
It Embedded Erase Algorithms Will automatically erase the entire chip or any combination of designed sector and
verify the erase sectors; Embedded Program algorithm automatically writes and verifies bytes at specified addresses

4.4 MCU/Scalar

The MCU control the keyboard signal and audio signal.
The GM5120 is a high performance, graphics processing IC for LCD monitors with resolutions at SXGA. On-chip
function include a high-speed triple-ADC and PLL, Ultra-Reliable DVI receiver, a high quality zoom and shrink
scaling engine, an on-screen display(OSD) controller, digital color controls and on-chip microcontroller (OCM),
5-Volt tolerance inputs ,low EMI and power management.

The analog input (CN602) signal and DVI-D input(CN601) signal are designed to be connected directly to scalar IC,
The MST9131A built-in LVDS transmitter, it is designed to be connected directly to panel.

4.5 Audio processor

IC802(PT2313L) is a four-channel digital control audio processor utilizing CMOS Technology. Volume, Bass,

5. Adjustment Procedure

5.1 General.

1. All specification must be met over line voltage range of 90V

to 264V

AC

50Hz / 60Hz, unless otherwise

AC

specified.

o

2. Operating temperature range is 0

C to 40oC with a relative humidity of 10% or less to 80%.

3. The monitor must be operational in a usable state within 30 minutes after turn-on.

4. All signal levels are measured assuming termination at the monitor’s input jacks or in its characteristic

impedance.

5. All controls must have excess range (no control may be left at an end stop when proper alignment is completed).

6. The monitor is not required to meet specs during the following but must tolerate, without damage to the LCD or

circuits, any sequence or combination of power on and off, signal on and off, erratic, wrong frequency or noisy
inputs while at any possible unplugging of power or signal, settings of user accessible controls likewise, the
monitor should survive extended periods of operation with line voltage reduced below the specified minimum.

7. An isolation transformer should be used when performing alignment and tests, Portions of the power supply

board are hot ground, The remaining boards are cold ground.

8. Ambient condition:

8.1 Illumination: In usual inspection of electric performance and mechanical performance, it shell be 150 ~
260lux.

8.2 Environmental noise: Less than 60dB.

8.3 Interference of EMI: The inspection shall be carried out in the place where a set is not disturbed by external
unnecessary electric wave and magnetic field.
