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.
To USB downstream port
of the USB compliant PC
or another hub cable
USB upstream Port
USB downstream Port
connect the cables from USB
compliant peripherals-such as
keyboard, mouse, etc

DESCRIPTION OF BLOCK DIAGRAM
1. Input Selection Circuit
This block is composed of 74LVC257(U1) and peripheral devices.
There are two input, Analog and Digital H/V Sync. LVC257 IC chooses one input and outputs selected input through
sync selection pin (Pin 1).
2. A/D Converter
This block is composed of AD9888 (U4) and passive devices.
Input video signal is amplified, Phase locked, A/D converted in this IC.
And send the Digital video signal to PW166B.
3. TMDS Receiver
This Block is composed of SiI161B (U201) and Peripheral devices.
This IC decodes CompositeInput signal from DVI-I Pin (J10) and make 8bit digital signal to send Digital signal to
PW166B.
4. Format Converter
This block is composed of PW166B (U8), M29W800AT (U9) and passive devices.
Micom in PW166B(Scaler)(U8) processes A/D Converter output, output of TMDS Receiver,
PW166B is Format Converter IC that receive Digital signal and output proper frame signal to LCD Module
(1600x1200).
5. Panel-Link Circuit
LVDS Transmitter(U401) is the IC that receives output digital signal of PW166B(U8) and output
composite signal to LCD Module.
Composite signal is the standard format for LCD Panel.
6. DC/DC Converter block
DC/DC Converters convert the input 12V to proper 2.5V, 3.3V, 5V, 12V for main board.
For shooting heat trouble, we use the DC/DC converting IC.
