The LCD TV will contain a main
board, a power board a function keyboard and an IR board. The main board and
power board will house the flat panel to control logic I2C bus, DDC, brightness
control logic for LCD panel, DC-DC conversion to supply the appropriate power
to the whole board and transmitting TTL level signals into LCD Module to drive
the LCD display circuit.The function keyboard and Remote Control will provide the OSD control signal to the Main Board.
The high voltage was only generated by Power support part, if
carelessly contacted the transformer on this module, can cause a serious shock.

This procedure gives you instructions for installing and using the LCD TV display.
(1) Position the display on the desired operation and plug the power cord into a convenient AC outlet. Three-wire power cord must be shielded and is provided as a safety precaution as it connects the chassis and cabinet to the electrical conduct ground. If the AC outlet in your location does not have provisions for the grounded type plug, the installer should attach the proper adapter to ensure a safe ground potential.
(2) Connect the 15-pin color display shielded signal cable to your signal system device and lock both screws on the connector to ensure firm grounding. The connector information is as follow:

The M220Z1-L03 model is a 22 inch
wide TFT-LCD module with a 4-CCFL Backlight Unit and a 30-pin 2ch-LVDS
interface. This module supports 1680 x 1050 WSXGA+ (16:10 wide screen) mode and
displays up to 16.7 million colors. The inverter module for the Backlight Unit
is not built in.
This monitor meets the Green
monitor standards as set by the Video Electronics Standards Association (VESA)
and/or the United States Environmental Protection Agency (EPA) and The Swedish
Confederation Employees (NUTEK). This feature is designed to conserve
electrical energy by reducing power consumption when there is no video-input
signal present. When there is no video input signals this monitor, following a
time-out period, will automatically switch to an OFF mode. This reduces the
monitor's internal power supply consumption. After the video input signal is
restored, full power is restored and the display is automatically redrawn. The
appearance is similar to a "Screen Saver" feature except the display
is completely off. The display is restored by pressing a key on the keyboard,
or clicking the mouse.
Upgrade
Firmware
Using USB port connecting PC
& MST99980 Board via ISP board as below. Turn on the monitor and run ISP
tool.
Click the button “Connect”, if it
can identify the type of the device, please click the “Dis Con” and then click
the “Connect” again.
Click the button “Read” to load
the software file and then click the “Auto”.
When the picture showed as below,
we can click the “run” to finish to upgrading.

Alignment method
Initial Set-up:
1. Select source as “VGA”.
2. Set Contrast = 50 (CMO) and Brightness=50 (CMO), at Standard menu mode.
3. Apply “PGCWRGB”(pattern-1) pattern by VGA pattern generator.
4. Enter factory mode menu: press “MENU+ “234” then enter FAC mode
Alignment:
1. At FAC mode menu, select FACTORY->Picture ->ADC -> Auto Colour item. Then press “>” key to adjust ADC_GAIN_R, ADC_GAIN_G, ADC_GAIN_B and ADC_OFFSET_R, ADC_OFFSET_G, ADC_OFFSET_B. Then store those values to NVM.
