The following tips may help you optimize your display:

• Adjust the computer's graphics card so that it outputs a 1280 x 1024 @ 60Hz video signal to
the LCD display . (Look for instructions on “changing the refresh rate” in the graphics 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.)

ViewSonic Corporation Confidential - Do Not Copy VA703b-3_VA703m-3

Main Menu Controls

Adjust the menu items shown below by using the up S and down T buttons.

Control Explanation

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.

Contrast adjusts the difference between the image background (black level)
and the foreground (white level).

Brightness adjusts background black level of the screen image.

Audio Adjust
Volume increases the volume, decreases the volume, and mutes the audio.
Mute temporarily silences audio output.

Color Adjust provides several color adjustment modes, including preset color

temperatures and a User Color mode which allows independent adjustment of
red (R), green (G), and blue (B). The factory setting for this product is 6500K
(6500 Kelvin).

sRGB-This 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-Adds blue to the screen image for cooler white (used in most office
settings with fluorescent lighting).

6500K-Adds red to the screen image for warmer white and richer red.

5400K-Adds green to the screen image for a darker color.

4. Circuit Description

2.1 Switching Mode Power Supply

2.1.1 AC Current Input Circuit

P801 is a connector for connecting AC Power. F801 is a fuse to protect all the circuit. AC input voltage is from
90V to 264V. R820 and R821 joined between two inputting main circuit to prevent man from shock. L801 is used to
clear up low frequency wave. C801 and C806 are used to discharge the waves that L801 produced. High
frequency waves are damped by C801 and C806. D801 is a rectifier which composed of 4 build-in diodes, it inverts
AC to DC.

2.1.2 High Voltage to Low Voltage Control Circuit

C805 is used to smooth the wave from rectifier. IC802 is a highly integrated PWM controller, which build-in a
power MOSFET. When rectified DC high voltage is applied to the DRAIN pin during start-up, the MOSFET is off
initially, and the CONTROL pin capacitor is charged through a switched high voltage current source connected
internally between the DRAIN and CONTROL pins. When the CONTROL pin voltage Vc reaches approximately

5.8V, the control circuitry is activated and the soft-start begins. The soft-start circuit gradually increases the duty
cycle of the MOSFET from zero to the maximum value over approximately 10ms. If no external feedback/supply
current is fed into the CONTROL pin by the end of the soft-start, the high voltage current source is turned off and
the CONTROL pin will start discharging in response to the supply current drawn by the control circuitry.

Resistor R803, R807, R824 and R825 are for line over voltage shut-down (OVP) and line under-voltage
detection (UVP).Resistors R801, R805, R822, and R823 are for external current limit adjustment, and used to
reduce the current limit externally to a value close to the operating peak current of primary about 1.35A. The mean
is power will protected when the primary current over about 1.35A.

When PWM is turned off, the main current flow will be consumed through D804 and ZD802, This will prevent

MOSFET which built-in IC802 from being damaged under large current impulse and voltage spike.

D806 and C815 provide internal Auxiliary current to CONTROL pin during normal operation. In addition, error

amplifier and feedback current to the CONTROL pin are for duty cycle control.

2.1.3 DC_5V and DC_14V Output Circuit

For DC 5V, D805 is used to rectify the inducted current. R806 and C811 are used to store energy when current

is reversed. The parts including C812, C814, C822, C821, B801 and L803 are used to smooth the current waves.

For DC 14V, D803 is used to rectify the inducted current. R802 and C802 are used to store energy when

current is reversed. The parts including C808, C810 and L802 are used to smooth the current waves.

2.1.4 Feedback and OVP Protect Circuit

Pin R of IC803 is supplied 2.5V stable voltage. It is connected to 5V and 14V output through R811,
R810 and R818. R811, R810 and R818 are output sampling resistor. When the sampling voltage more
than 2.5V or less than 2.5V, feedback current of IC802 will change, this can change the voltage from
transformer T801.

Q802, R827, R828 and ZD801 make up of dummy loading circuit. For start-up sequence, during 5V
output take place high loading first, this dummy loading circuit operated to insure 14V not be increased.

2. 2 Inverter Circuit

2.2.1 Low voltage to high voltage circuit

14VDC provides the power for IC501; the control signals Brightness and ON/OFF come from I/F board.
ON/OFF signal connect to pin10 of IC501 and makes IC501 enable. Brightness signal connect to pin4 of IC501
and regulates the panel brightness, R526, R529, C505 make up a network of delaying time circuit and R523, R524
make up a divided voltage network, C504 is used to dump noise. The operation frequency is determined by the
external Resistor R522 and capacitor C529 connected to pin13 of IC501. BURST MODE regulated dimming
frequency is determined by the external resistor R527 and capacitor C506 connected to pin11 of IC501. C508 is
used for soft start and compensation, C507, C505 are used for dump noise.

The output drives, include DRV1, DRV2 (pins1,15 respectively) output square pulses to drive MOSFET U501,
U502, and each of U501, U502 , is consist of a N channel MOSFET. U501,OR U502 work as Push-Pull- topology, it
is high efficient, PWM switching.

During start up, VSEN (pin6) senses the voltage at the transformer secondary. When VSEN reaches 3.0V, the

output voltage is regulated. If no current is sensed approximately 2seconds IC501 shut off.

The current flowing through CCFL is sensed and regulated through sense resistor R509, R534. The feedback
voltage connected to Pin5 (ISEN), then compared with a reference voltage (1.5V) via a current amplifier, resulting in
PWM drive outputs to PUSH-PULL switches.

2.2.2 Protection circuit

Over Voltage Protection and over-current protection are monitored by the voltage on VSEN(Pin 6) During
normal operation , if a CCFL is damaged or removed ,the voltage at VSEN (Pin6) increases .Once the voltage at
VSEN exceeds 2.0V (OVPT Setting) the driver output duty cycle is regulated and the shutdown delay timer is
activated.OVPT set the overall protection threshold voltage that is lower than 3V (VSEN threshold). Once the
voltage at TIMER pin reached about 3v ,the IC will shut down and latch .R501, R503,C525,C527 are connected in
high voltage output connector, the divided AC voltage is inverted DC voltage through D503,
D504,D507,D508 ,R530 and C516are used to rectify wave & dump noise. Then the voltage signal reaches Pin6
VSEN of IC501, when the voltage changes, build-in PWM of IC501 will adjust output voltage.

Open Lamp Protection: In normal operation, R509 are sensed a high level DC voltage,If a CCFL is removed
or damaged during normal ,the voltage at SSTCMP(Pin12) rises rapidly .when the voltage at SSTCMP reaches a
threshold of approximately 2.5V,a current source charges the capacitor(C511)connected to TIMER(Pin3).Once the
voltage level at the TIMER pin reaches a threshold of approximately 3v,The drive outputs shut down and latch.

4. Power On/Off Sequence

4.1 Hardware Power ON

When power cord is plugged into AC socket, SMPS starts work and provides U105 with VCC5V. When VCC5V
inputs, U105 resets circuit active, sets U105 all registers to preset modes, and then monitor goes into stand-by
mode. That means hardware power on has been completed.

4.2 Software Power ON/OFF

When press power key, U105 # 90 recieves low pulse,and then U105 will do the power on/off.

- If Power ON, U105 # 91(LED_Green) will send out Low potential, and then LED green on.

- If Power OFF, U105 # 91(LED_Green) will send out High potential, and then LED Off.

The Panel_Vcc, Backlight_En, CLK/DATA output to panel will follow the following sequency.

6. Troubleshooting Flow Chart

1. Common Acknowledge

z If you change the interface board, be sure that the U103, U105, U106 and U108 these three

components also changed to the new I/F board because there was program inside. If not, please
re-write EDID and upload firmware into U106 via VGA Cable.

z If you adjust clock and phase, please do it at the condition of Windows shut down pattern.
z If you confirm the R.G.B. color is normal or not, please do it under 16-grey scalar pattern.
z This LCM is analog interface. So if the entire screen is an abnormal color that means the problem

happen in the analog circuit part, if only some scale appears abnormal color that stand the
problem happen in the digital circuit part.

z If you check the H/V position, please use the crosshatch pattern.
z This LCM support more than 30 timing modes, if the input timing mode is out of specification, the

picture may appears abnormally.

z If brightness uneven, repairs Inverter circuit or change a new panel.
z If you find the vertical line or horizontal line lost on the screen, please change panel.
z If you find the speaker don’t working, please don’t plug in audio cable, unless change new speaker.
