WARNING FOR THE SAFETY-RELATED COMPONENT.
• There are some special components used in LCD
monitor that are important for safety. These parts are
marked on the schematic diagram and the
replacement parts list. It is essential that these critical
parts should be replaced with the manufacturer’s
specified parts to prevent electric shock, fire or other
hazard.
• Do not modify original design without obtaining written
permission from manufacturer or you will void the
original parts and labor guarantee.
TAKE CARE DURING HANDLING THE LCD MODULE
WITH BACKLIGHT UNIT.
• Must mount the module using mounting holes arranged
in four corners.
• Do not press on the panel, edge of the frame strongly
or electric shock as this will result in damage to the
screen.
• Do not scratch or press on the panel with any sharp
objects, such as pencil or pen as this may result in
damage to the panel.
• Protect the module from the ESD as it may damage the
electronic circuit (C-MOS).
• Make certain that treatment person’s body are
grounded through wrist band.
• Do not leave the module in high temperature and in
areas of high humidity for a long time.
• The module not be exposed to the direct sunlight.
• Avoid contact with water as it may a short circuit within
the module.
• If the surface of panel become dirty, please wipe it off
with a softmaterial. (Cleaning with a dirty or rough cloth
may damage the panel.)
WARNING
BE CAREFUL ELECTRIC SHOCK !
• If you want to replace with the new backlight (CCFL) or
inverter circuit, must disconnect the AC adapter
because high voltage appears at inverter circuit about
650Vrms.
• Handle with care wires or connectors of the inverter
circuit. If the wires are pressed cause short and may
burn or take fire.
PRECAUTION
CAUTION
Please use only a plastic screwdriver to protect yourself
from shock hazard during service operation.

Making use of USB (Universal Serial Bus)*
USB (Universal Serial Bus) is an innovation in connecting your different desktop peripherals conveniently to your computer.
By using the USB, you will be able to connect your mouse, keyboard, and other to your monitor instead of having to
connect them to your computer. This will give you greater flexibility in setting up your system. USB allows you to connect
chain up to 120 devices on a single USB port, and you can “hot”plug (attach them while the computer is running) or unplug
them while maintaining Plug and Plug auto detection and configuration. This monitor has an integrated BUS-powered USB
hub, allowing up to 2 other USB devices to be attached it.
USB connection
1. Connect the upstream port of the Display to the downstream port of the USB compliant PC or another hub using the
USB cable. (Computer must have a USB port)
2. Connect the USB compliant peripherals to the downstream ports of the monitor.
NOTE
To activate the USB hub function, the monitor must be connected to a USB compliant PC(OS) or another hub with the USB
cable(enclosed).
When connecting the USB cable, check that the shape of the connector at the cable side matches the shape at the connecting
side.
Even if the monitor is in a power saving mode, USB compliant devices will function when they are connected the USB ports(both
the upstream and downstream) of the monitor.
USB downstream Port
connect the cables from USB
compliant peripherals-such as
keyboard, mouse, etc
This is a simplified representation
of rear view.
To USB downstream port
of the USB compliant PC or
another hub cable

1. Scaler One chip IC(GMZAN-2, U201)
GMZAN-2 (U201) is one chip IC which it supports four internal function blocks of Video Amp, PLL,
A/D converter and Video processor.
Video signal (0.7Vp.p) clamped through C207, 208, 209 with matching IC’s proper cut off voltage.
This signal is processed as a proper 8 bit digital signal by U201’s amplifying, phase locking, A/D converting,
and scaling operations.
Also, U201 generates Clock, Horizontal and Vertical sync, Data Enable signals as LVDS IC’s input signals.
2. System Controller (Microprocessor) Circuit
1) Microprocessor (U501) distinguishes polarity and frequency by calculating horizontal and vertical sync input
from signal source.
2) Microprocessor (U501) carries out power control by sending power-down trigger signal to each IC.
3) Microprocessor (U501) communicates with EEPROM (U502), and GMZAN-2 (U201)
through IIC(2 lines) or 4 bit bus line. It makes all devices operated properly.
4) Microprocessor (U501) let User adjust screen by OSD function.
3. LVDS(Low Voltage Differential Signal, U411)
LVDS transmitter (U411) delivers digital signal to the receiver inside LCD module by method of abstraction.
The abstracted signals are pairs of RIN0+-, RIN1+-, RIN2+-, RIN3+-, and RCLKIN+- of which voltage swing
is 0.5V each.
When SHUTON pin’s input is High, transmitter goes to power down mode.
4. DC/DC block
This block is composed of regulators which supplies 2.5V, 3.3V, and 5V.
Each regulator’s source power is 5VS and 12V from power block.
U806 supplies 2.5VD and 2.5VA and U802 supplies 3.3VD, 3.3V_AD, and 3.3V_PL powers to GMZAN-2’s
internal PLL, ADC, Pre-amp, and scaler by dropping down 5VS from power block.
U805 supplies MODPWR-3.3V for LCD module’s operation by dropping down 5VS from power block.
U803 supplies 5VR for Microprocessor and Logic IC(U701)’s operation by dropping down 12V from power block.
5. Power Block
This block supplies DC voltages of 5VS and 12V by converting AC input voltage of 100~240Vac.
Converting method is SMPS(Switching Mode Power Supply).
