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.

SDM-HS94/HS94P (E)
DESCRIPTION OF BLOCK DIAGRAM
1. Video Controller Part & Display Data Transmitter Part.
This part amplifies the level of video signal for the digital conversion and converts from the analog video signal to the
digital video signal using a pixel clock.
The pixel clock for each mode is generated by the PLL.
The range of the pixel clock is from 25MHz to 135MHz.
This part consists of the Scaler, LVDS Tx, TMDS Rx, Reset IC.
The Scaler gets the video signals which were converted analog to digital, interpolates input to 1280 x 1024
resolution signal and outputs 8-bit R, G, B signal to transmitter.
Especially pre-amp / ADC / Video controller/ Transmitter are merged to one chip ‘MST9131A’ by MST.
This part transmit digital signal from the Scaler to the receiver of module.
2. Power Part
This part consists of the one 3.3V and one 2.5 regulators to convert power which is provided 5V by LIPS Board.
In particular, 5V is provided for LCD Panel. There is also 12V which is for Audio power.
Also, 5V is converted 3.3V and 2.5V by regulator. Converted power is provided for IC in the main board.
3. 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 (704), and MST9131A (U201) through IIC or 8 bit bus line.
It is enable to control and communicate each devices.
4) Microprocessor (U501) let User adjust screen by OSD function.

1. EMI components.
This part contains of EMI components to comply with global marketing EMI standards like FCC, VCCI CISPR, the
circuit included a line-filter, across line capacitor and of course the primary protection fuse.
2. Input rectifier and filter.
This part function is for transfer the input AC voltage to a DC voltage through a bridge rectifier and a bulk capacitor.
3. Energy Transfer.
This part function is transfer the primary energy to secondary through a power transformer.
4. Output rectifier and filter.
This part function is to make a pulse width modulation control and to provide the driver signal to power switch, to
adjust the duty cycle during different AC input and output loading condition to achive the dc output stablize, and also
the over power protection is also monitor by this part.
5. Photo-Coupler isolation.
This part function is to feed back the dc output changing status through a photo transistor to primary controller to
achieve the stabilized dc output voltage.
6. Signal collection.
This part function is to collect the any change from the dc output and feed back to the primary through photo
transistor.
