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 a high quality, safety approved AC/DC power cord.
(5) Disconnect the power plug from the AC outlet if the product will not be 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 containing excessive dust and dirt.
- Near any appliance generating a strong magnetic field.
- 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 connecting or disconnecting input connector.
(3) Wipe off water drops 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 ensure human earth when handling.
(7) Do not open or modify the Module Assembly.
(8) Do not press the reflector sheet at the back of the module in any direction.
(9) In the event that a Module must be put back into the packing container slot after it was taken out of 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 or 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 or
bend the TFT Module even momentarily. When designing the enclosure, it should be taken into consideration
that no bending/twisting forces may be applied to the TFT Module from outside. Otherwise the TFT Module
may be damaged.
(12) The cold cathode fluorescent lamp in the LCD contains a small amount of mercury. Please follow local
ordinances or regulations for disposal.
(13) The LCD module contains a small amount of materials having no flammability grade. The LCD module
should be supplied with power that complies with the requirements of Limited Power Source
(IEC60950 or UL1950), or an exemption should be applied for.
(14)The LCD module is designed so that the CCFL in it is supplied by a Limited Current Circuit (IEC60950
or UL1950). Do not connect the CCFL to a Hazardous Voltage Circuit.

6. THEORY OF OPERATION
This section describes the function of the LCD monitor per functional block.
This monitor includes MB board, power board and button board.
6.1 MB BOARD
The MB board is a two-layer, single-landed design with ground and internal planes provided. DC power from the
power board enter the board through a 6P cable. Other connector on the board is for button board .The VGA cable
is a signal cable that contains video signal, sync signal and DDC signal from PC VGA adapter. This system board
consists of 4 functional areas : flat panel controller, MCU with flash ROM , power regulator .
6.1.1 Flat panel controller… RTD2013(U7)
The heart of the system board is Realtek RTD2013. The RTD2013 is a graphics processing IC for LCD monitor.
It provides all key IC functions required for LCD panel. On-chip functions include a high-speed triple-ADC , PLL,
high scaling engine, OSD controller.
a) Clock Generation :
Crystal Input Clock (TCLK and XTAL). This is the input pair to an internal crystal oscillator and
corresponding logic. A 24.576 MHz crystal is recommended.
b) Analog to Digital Converter:
The RTD2013 chip has three ADC's (analog-to-digital converters), one for each color (red, green and
blue) .The analog RGB signals are connected to RTD2013 as described below
Pin Name Pin Number
Red + 37
Red - 38
Green + 34
Green - 35
Blue + 30
Blue - 31
c) OSD : The RTD2013 has a fully programmable ,high-quality OSD controller. The on-chip static
RAM(4096 words by 24 bits) stores the cell map and the cell definitions.

d) MTV312 Micro controller: The MTV312 micro controller(MCU) serves as the system micro controller. It’s
programs the RTD2013 and manages other devices in the system such as the keypad, the backlight, LED,
audio and non-volatile RAM. using general purpose input/output (GPIO) pins.

16 P6.2 LCD panel power1 on / off control
17 P1.0 Backlight on / off control
e) Panel Power Sequencing ( PANEL_PW12,3) ( Pin 16, 18) : The MTV312 has two dedicated outputs
VDDCTRL1 and 2 ( Pin32 and Pin3) to control LCD power sequencing once data and control signals
are stable.
f) Panel interface (Pin73~94) : The RTD2013 driver interface is highly programmable. It supports dual bus /
dual port for XGA drivers.
6.1.2 Power Regulator AIC1563 (U2),AIC1739-25CX(U10) : The AIC1563 is a monolithic control IC
containing the primary functions required for DC to DC converters. The device consists of an
internal temperature compensated reference, comparator, controlled duty cycle.
Oscillator with an active current sense circuit. Desired output voltage are determined by the equation,
Volt = 1.25 ( 1 + R11 / R12), In this case, the output voltage are 3.3Volts
The AIC1563 is a low dropout positive adjustable regulator with minimum of 1A output current capability.
So it is well suited for 2.5 V Regulator.
6.1.3 Power Regulator AIC1739-25CX(U10) : The AIC1739-25CX is a monolithic control IC containing the
primary functions required for DC to DC converters. The device consists of an internal
temperature compensated reference, comparator, controlled duty cycle.
Oscillator with an active current sense circuit. Desired output voltage are determined by the
output function, the output voltage are 2.5 Volts for scaler power.
6.2 Power(Inverter) Board
