1.1. SAFETY PRECAUTIONS
This LCD TV is manufactured and tested on a ground principle that a user's safety comes first.
However, improper use or installation may cause damage to the LCD TV as well as to the user.
Carefully go over the following WARNINGS before installing and keep this guide handy.
WARNINGS:
This LCD TV should be operated only at the correct power sources indicated on the label
on the rear end of the LCD TV. If you're unsure of the power supply in your residence,
consult your local dealer or power company.
Use only the special power adapter that comes with this LCD TV for power input.
Do not try to repair the LCD TV yourself as it contains no user-serviceable parts. This
LCDTV should only be repaired by a qualified technician.
Do not remove the LCD TV cabinet. There is high-voltage parts inside that may cause
electric shock to human bodies, even when the power cord is unplugged.
Stop using the LCD TV if the cabinet is damaged. Have it checked by a service technacian.
Put your LCD TV only in a clean, dry environment. If it gets wet, unplug the power cable
immediately and consult your service technician.
Always unplug the LCD TV before cleaning it. Clean the cabinet with a clean, dry cloth.
Apply non-ammonia based cleaner onto the cloth, not directly onto the glass screen.
Keep the LCD TV away from magnetic objects, motors, TV sets, and transformer.
Do not place heavy objects on the LCD TV or power cord.
1.2. PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety visual inspections and
the protection afforded by them cannot necessarily be obtained by using replacement
components rated for higher voltages, wattage, etc. Before replacing any of these components
read the parts list in this manual carefully. The use of substitute replacement parts which do not
have the same safety characteristics as specified in the parts list may create shock, fire, or other
hazards.
1.3. SERVICE NOTES
1. When replacing parts or circuit boards, clamp the lead wires around terminals before
soldering.
2. When replacing a high wattage resistor (more than 1W of metal oxide film resistor) in circuit
board, keep the resistor about 5mm away from circuit board.
3. Keep wires away from high voltage, high temperature components and sharp edges.
4. Keep wires in their original position so as to reduce interference.

LCD TV Handling Precautions
1. Handling Precautions
(1) Since front polarizer is easily damaged, pay attention not to scratch it.
(2) Be sure to turn off power supply when inserting or disconnecting from input connector.
(3) Wipe off water drop immediately. Long contact with water may cause discoloration or spots.
(4) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
(5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface.
(6) Since CMOS LSI is used in this module, take care of static electricity and insure human earth
when handling.
(7) Do not open nor modify the Module Assembly.
(8) Do not press the reflector sheet at the back of the module to any directions.
(9) In case if a Module has to be put back into the packing container slot after once it was taken
out from the container, do not press the center of the CCFL Reflector edge. Instead, press at
the far ends of the CFL Reflector edge softly. Otherwise the TFT Module may be damaged.
(10) At the insertion or removal of the Signal Interface Connector, be sure not to rotate nor tilt the
Interface Connector of the TFT Module.
(11) After installation of the TFT Module into an enclosure (LCD TV housing, for example), do
not twist nor bend the TFT Module even momentary. At designing the enclosure, it should be
taken into consideration that no bending/twisting forces are applied to the TFT Module from
outside. Otherwise the TFT Module may be damaged.
(12) Cold cathode fluorescent lamp in LCD contains a small amount of mercury. Please follow
local ordinances or regulations for disposal.
(13) Small amount of materials having no flammability grade is used in the LCD module. The
LCD module should be supplied by power complied with requirements of Limited Power
Source (IEC60950 or UL1950), or be applied exemption.
(14) The LCD module is designed so that the CFL in it is supplied by Limited Current Circuit
(IEC60950 or UL1950). Do not connect the CFL in Hazardous Voltage Circuit.
2. Handling and Placing Methods
Correct Methods:
Incorrect Methods:
Only touch the metal frame of the LCD panel Surface of the LCD panel is pressed by fingers
or the front cover of the LCD TV. Do not touch and that may cause “Mura”

Working Theorem
A. A/D converter (PC & YPbPr) and DVI(HDCP) input
The MST5151LA offers designers the flexibility of an analog interface and High-Definition
Multimedia Interface (DVI) receiver integrated on a single chip. Also included is support for High
bandwidth Digital Content Protection (HDCP).
Analog Interface
The MST5151LA is a complete 8-bit 165 MSPS monolithic analog interface optimized for
capturing Component Video (YPbPr) and RGB graphics signals. Its 165 MSPS encode rate
capability and full power analog bandwidth of 300 MHz supports all HDTV formats (up to 1080p)
and FPD resolutions up to UXGA (1600 x 1200 @ 60 Hz). The analog interface includes a 165
MHz triple ADC with internal 3.3V reference, a Phase Locked Loop (PLL), and programmable
gain, offset, and clamp control. The user provides only 1.8V and 3.3V power supply, analog input,
and Hsync. Three-state CMOS outputs may be powered from 1.8V to 3.3V. The MST5151LA
on-chip PLL generates a pixel clock from Hsync. Pixel clock output frequencies range from
12MHz to 165 MHz. PLL clock jitter is typically less than 500 ps p-p at 165 MHz. The
MST5151LA also offers full sync processing for composite sync and Sync-on-Green (SOG)
applications.
Digital Interface
The MST5151LA contains a DVI(HDCP) 1.0 compatible receiver and supports all HDTV
formats (up to 1080p) and display resolutions up to UXGA (1600 x 1200 @ 60 Hz). The receiver
features an intra-pair skew tolerance of up to one full clock cycle. With the inclusion of HDCP,
displays may now receive encrypted video content. The MST5151LA allows for authentication of
a video receiver, decryption of encoded data at the receiver, and renew ability of that
authentication during transmission as specified by the HDCP v1.1 protocol.
Fabricated in an advanced CMOS process, the MST5151LA is provided in a space-saving
100-lead LQFP surface-mount Pb free plastic package and is specified over the 0 oC to 70 oC
temperature range.
B. Video Decoder (video)
The SAA7117 is a highly integrated NTSC, PAL, and SECAM video decoder support for high
quality LCD-TV video applications, SAA7117 supports NTSC/PAL chroma and luma separation
using a 2-dimensional adaptive comb filter for reducing the cross-luma and cross-chroma artifacts.
The frame buffer is also use for 2D noise reduction circuit that resumes good visual quality when
the input signal is a noisy video source
The SAA7117 10-bits CMOS Analog-to-Digital Converters(ADC) at four-fold ”ITU656”
oversampling(54MHZ);Sixteen analog input pins.allowing fo multiple combinations of
composite.S-Video component video;Eight 3-level capable sensor pins for D-connector or SCART
AV- and RGB- switch signals(three of those can be active simultaneously),one Fast blanking
input;Level sensitive fast blanking(RGB switch control);I²C read back of digital AGC gain factor;
The component, composite, or S-Video signals are sampled at a free-run external clock frequency
(10~58.6 MHz). After the video decoder processing, the video data was sent out with a line-locked
alignment rate (24.576 MHz).
The SAA7117 comes with 160-pin QFP package.
