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, due to the high voltage used in the inverter circuit.
High voltage is 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. The AC cord is detachable , but the
DC cord is permanently attached . Any attempt to replace another adapter could result in damage to 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 with 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 dislay. (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 dislay.)

sRGB
— sRGB is quickly becoming the industry standard for color
management, with support being included in many of the latest
applications. Enabling this setting allows the LCD display to
more accurately display colors the way they were originally
intended. Enabling the sRGB setting will cause the Contrast and
Brightness adjustments to be disabled.
9300K

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 adapter enters the board through
DC jack. Other connectors on the board are for inverter, audio and button boards .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, flash ROM, power regulator and Audio amplifier
6.1.1 Flat panel controller… MST1831A (U3)
The heart of the system board is the scalar chip of MST1831A. The MST1831A 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 (U6). It is active high.
c) Analog to Digital Converter:
The MST1831A 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 MST1831A 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

Page 22
d) OSD: The MST1831A 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 MST1831A integrated DVI receiver, which operates up to 135MHz and can
directly connect to all DVI compliant transmitters. The TMDS signals are connected to MST1831A
as described below:
The MST1831A driver interface is highly programmable. It supports dual bus / dual port for SXGA drivers.
6.1.2 Power Regulator AIC1563 (U9), LT1117 (U10, U11): 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 is determined by the equation,
Volt = 1.25 *(1 + R121 / R122), in this case, the output voltage are 5 Volts
The AIC1117 is a low dropout positive adjustable regulator with minimum 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 is determined by the equation
Volt=1.25 x (1 + R124/R123)= 2.5
U11 as a 3.3V regulator, Desired output voltage is determined by the equation
Volt=1.255 x (1+ R126/R125)= 3.3

6.2 Audio Amplifier TPA3002D2 (U7)
The TPA3002D2 is a 9-W per channel efficient, Class-D audio amplifier for driving bridged-tied stereo speakers.
TPA3002D2 can directly drive 8 ohms speaker, does not require output coupling capacitor, bootstrap capacitor,
or LC filter. Audio line-in is fed into pin 2,6 of the TPA3002D2. The output gain is controlled by pin 11. It also
provides line outputs for external headphone with a range of gain control from –56dB to 20dB.
6.3 Earphone Amplifier LM4881 (U8)
The LM4881 is a dual audio power amplifier for earphone application. It provides high quality output power
(THD at 1 KHz at 75mW continuous average output power into 32ohm load) with a minimal amount of external
components. It features thermal shutdown protection circuit and no bootstrap capacitors or snubber circuits are
necessary.
