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 .

VA2012w-2_VA2012wb-2
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. Input adjusts the Analogue or the Digital input source
E. Audio Adjust the volume increase or decrease and mute function
F.
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.
G. 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.
H. 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.
I.
OSD Position allows you to move the on-screen display menus and control screens.
J.
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.

6. THEORY OF OPERATION
This section describes the function of the LCD monitor per functional block.
This monitor includes MB board, power board, Inverter board and button board.
6.1 MB BOARD
The MB board is a two-layer, single-landed. 12V DC power from the power adapter enters the board through connector CN6.
Other connectors on the board are for audio speaker and 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, flash ROM, power regulator and Audio amplifier
6.1.1 Flat panel controller… NT68563HF (IC2)
The heart of the system board is the scalar chip of NT68563HF. The scaler is a highly integrated flat panel display controller
that interfaces analog, digital, and video inputs. It combines a triple ADC, a DVI compliant TMDS receiver, a multi-color on
screen display (OSD) controller and many other functions in a single chip. It provides user a simple, flexible and cost-effective
solution for various flat panel display products.
The NT68563HF operates at frequencies up to 205MHz (analog only), suitable for LCD monitor up to UXGA resolution. The
NT68563HF also build-in noise reduction function to provide more stable video quality, spread spectrum to provide low EMI
solution, sRGB for video color space convert, post pattern for manufacture test.
a)
Clock Generation:
This is the input pair to an internal crystal oscillator and corresponding logic. A 12.000 MHz crystal is
recommended.
b) Hardware Reset (Pin127):
Hardware Reset signal is provided by MCU (IC3), it is active high.
c)
Analog to Digital Converter:
The NT68563HF chip has triple ADC's (analog-to-digital converters), one for each color (red, green and blue) .The
analog RGB and synchronous signals are connected to NT68563 as described below:

e)
On chip TMDS receiver: The NT68563HF integrated TMDS receiver, which operates up to 165MHz and can directly
connect to all DVI compliant TMDS transmitters. The TMDS signals are connected to NT68563HF as described bellow:

6.1.2 Mcu flash ROM
This is an 8031 CPU core embedded micro-controller, which is design for high-performance low-cost LCD monitor control
application. It contains an 8-bit 8031 micro-controller, on-chip 64 K bytes flash-type program ROM, 1,280-bytes internal
data memory, four 7-bit resolution A/D Converter, 10-channel 8-bit resolution PWM DAC, two 16-bit timer/counters, and a
UART.
a) PWM controlling function (Pin 8, Pin 9): The MCU 68F633 has two GPIO to control audio volume and back light
brightness.
b) Serial interface ports pin 25~26(DVI) and pin 27~28(VGA): This serial interface ports communicate with MCU and
support up to 400Kbit per second transmit rate.
6.1.2 Power Regulator AIC1563 (U1), AIC1117 (U3, U4, U5): 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 + R121 / R122), in this case, the output voltage are 5 Volts
AIC1117 (U3, U4, U5): 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.
U5 as a 1.8V regulator, desired output voltage are determined by the equation
Volt=1.25 x (1 + R90/R88) = 1.8
U3 as a 3.3V regulator, desired output voltage are determined by the equation
Volt=1.255 x (1+ R86/R85) = 3.3
U4 as a 3.3V regulator, desired output voltage are determined by the equation
Volt=1.255 x (1+ R89/R87) = 3.3
6.2 Audio Amplifier UTC TDA7496L (U9)
The TDA7496L is a stereo 2W+2W class AB power amplifier; Features of the TDA7496L include linear volume control,
Stand-by and mute functions.
