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 internal 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 power board 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 .

The following tips may help you optimize your display:
• 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
refresh rate” in your graphic card's user guide.)
• If necessary, make small adjustments using H POSITION and V POSITION
until the screen image is completely visible
. (The black border around the
edge of the screen should barely touch the illuminated “active area” of the
LCD display.)

6. THEORY OF OPERATION
This section describes the function of the LCD monitor per functional block.
This monitor includes MB board, inverter board, adapter and two button boards.
6.1 MB BOARD
The MB board is a two-layer, single-landed. 12V DC power from the power board enters the board through
6P connector (CN6)...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 3 functional areas: flat panel controller, flash ROM,
power regulator.
6.1.1 Flat panel controller… MST8131A (U3)
The heart of the system board is the scalar chip of MST8131A. The MST8131A is a high performance,
dual input graphics processing IC for LCD monitors with resolutions up to SXGA. It provides all key IC
functions required for LCD panel. On-chip functions include an 8-bit triple ADC, PLL, DVI receiver,
high scaling engine, OSD controller and dual LVDS transmitter.
a) Clock Generation:
Crystal Input Clock (XIN and XOUT): This is the input pair to an internal crystal oscillator
and corresponding logic. A 14.318 MHz crystal is recommended.
b) Hardware Reset (Pin 32):
Hardware Reset signal is provided by MCU (U5). It is active high.
c) Analog to Digital Converter:
The MST8131A chip has three ADC's (analog-to-digital converters), one for each color (red, green
and blue) .The analog RGB and synchronous signals are connected to MST8131A as described below:
Pin Name Pin Number
Red + 63
Red - 62
Green + 60
Green - 59
Blue + 58
Blue - 57
H sync 37
V sync 38
d) OSD: The MST8131A has a fully programmable, high-quality OSD controller. The on-chip static
RAM stores the cell map and the cell definitions.

e) On
chip TMDS receiver: The MST8131A integrated DVI receiver, which operates up to 135MHz
and can directly connect to all DVI compliant transmitters. The TMDS signals are connected to
MST8131A as described bellow:
Pin Name Pin NO.
R+ 40
R- 41
G+ 43
G- 44
B+ 46
B- 47
CK+ 49
CK- 50
f) PWM controlling function (Pin 73~74): The MST8131A has two dedicated PWM outputs of
PWM0 and PWM1 to control audio volume and back light brightness.
g) Serial interface ports (pin 70 and
pin 71): This serial interface ports communicate with MCU
and support up to 400Kbit per second transmit rate.
h) Panel interface (Pin 1, Pin 102, Pin 103, Pin 106, Pin 107, Pin 120~ Pin 125,
Pin 108~113,
and Pin 128) : The MST1831A driver interface is highly programmable. It supports dual bus / dual
port for SXGA drivers.
6.1.2 Power Regulator AIC1563 (U21), LT1117 (U22, U23): 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 + R66 / R67), in this case, the output voltage are 5 Volts
The AIC1117 is a low dropout positive adjustable regulator with minim
um of 800mA output current
capability. So it is well suited for 3.3 V and 2.5 V Regulator.
U10 as a 2.5V regulator, Desired output voltage are determined by the equation
Volt=1.25 x (1 + R84/R83)= 2.5
U11 as a 3.3V regulator, Desired output voltage are determined by the equation
Volt=1.255 x (1+ R86/R85)= 3.3
