1. Precautions and Safety Notices

1. Appropriate Operation

(1) Turn off the product before cleaning.
(2) Use only a dry soft cloth when cleaning the LCD panel surface.
(3) Use a soft cloth soaked with mild detergent to clean the display housing.
(4) Use only a high quality, safety approved AC/DC power cord.
(5) Disconnect the power plug from the AC outlet if the product will not be used for a long period of time.
(6) If smoke, abnormal noise, or strange odor is present, immediately switch the LCD display off.
(7) Do not touch the LCD panel surface with sharp or hard objects.
(8) Do not place heavy objects on the LCD display, video cable, or power cord.
(9) Do not use abrasive cleaners, waxes or solvents for your cleaning.
(10) Do not operate the product under the following conditions:

 Extremely hot, cold or humid environment.
 Areas containing excessive dust and dirt.
 Near any appliance generating a strong magnetic field.
 In direct sunlight.

2. Caution

No modification of any circuit should be attempted. Service work should only be performed after you are thoroughly

familiar with all of the following safety checks and servicing guidelines.

3. Safety Check

Care should be taken while servicing this LCD display. Because of the high voltage used in the inverter circuit, the

voltage is exposed in such areas as the associated transformer circuits.

4. LCD Module Handling Precautions

4.1 Handling Precautions

(1) Since front polarizer is easily damaged, pay attention not to scratch it.
(2) Be sure to turn off power supply when connecting or disconnecting input connector.
(3) Wipe off water drops 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 ensure human earth when handling.
(7) Do not open or modify the Module Assembly.
(8) Do not press the reflector sheet at the back of the module in any direction.
(9) In the event that a Module must be put back into the packing container slot after it was taken out of 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 or tilt the Interface Connector of

the TFT Module.

(11) After installation of the TFT Module into an enclosure (LCD monitor housing, for example), do not twist or bend the

TFT Module even momentarily. When designing the enclosure, it should be taken into consideration that no

bending/twisting forces may be applied to the TFT Module from outside. Otherwise the TFT Module may be

damaged.

(12) The cold cathode fluorescent lamp in the LCD contains a small amount of mercury. Please follow local ordinances

or regulations for disposal.

(13) The LCD module contains a small amount of materials having no flammability grade. The LCD module should be

supplied with power that complies with the requirements of Limited Power Source (IEC60950 or UL1950), or an

exemption should be applied for.

(14) The LCD module is designed so that the CCFL in it is supplied by a Limited Current Circuit (IEC60950 or

UL1950). Do not connect the CCFL to a Hazardous Voltage Circuit

Correct methods : Incorrect Methods :

Only touch the metal-frame of the panel or the front

cover of the monitor. Do not touch the surface of the

polarizer .

Surface of the panel is pressed by fingers & this may

cause “ MURA “

Take out the monitor Take out the monitor by grasping the LCD panel.

That may cause “ MURA“.

Place the monitor on a clean & soft foam pad . Place the monitor on foreign objects .

That could scratch the surface of panel

Note 3: OSD Lock should not lock Power Button and Power Lock function

Power Lock short cuts function for the buttons

The power button lock will be activated by pressing the front panel control buttons "(1), & (▼)" for 10 seconds. Locking the

power button means that the user won't be able to turn off the LCD while the power button is locked. If the user presses the

power button while it is locked, a message will appear on the screen for 3 seconds showing "Power Button Locked". It also

means that with the power button locked, the LCD would automatically turn back "On" when power is restored after a power

failure. If the power button is not in the locked mode, then power should return to it's previous state when power is restored

after a power failure. The power button lock will be deactivated by pressing the front panel control buttons "(1), & (▼)"

again for 10 seconds.

The PCM1754 is a CMOS, monolithic, integrated circuit, which includes stereo digital-to-analog converters and support
circuitry in a small 16-lead SSOP package. The data converters use TI’s enhanced multilevel delta-sigma architecture,
which employs 4th-order noise shaping and 8-level amplitude quantization to achieve excellent dynamic performance and
improved tolerance to clock jitter. The PCM1754 accepts industry-standard audio data formats with 16- to 24-bit data,
providing easy interfacing to audio DSP and decoder chips. Sampling rates up to 200 kHz are supported. A full set of
user-programmable functions is accessible through a three-wire serial control port, which supports register write functions.

The TPA3005D2 is a 6-W (per channel) efficient, Class-D audio amplifier for driving bridged-t ied stereo speakers.
The TPA3005D2 can drive stereo speakers as low as 8 Ω. The high efficiency of the TPA3005D2 eliminates the
need for external heatsinks when playing music. The gain of the amplifier is controlled by two gain select pins. The
gain selections are 15.3, 21.2, 27.2, and 31.8 dB. The outputs are fully protected against shorts to GND, VCC, and
output-to-output shorts. Thermal protection ensures the maximum junction temperature is not exceeded.

The TVP5147 device is a high-quality, single-chip digital video decoder that digitizes and decodes all popular
baseband analog video formats into digital component video. The TVP5147 decoder supports the analog-to-digital
(A/D) conversion of component YPbPr signals, as well as the A/D conversion and decoding of NTSC, PAL, and
SECAM composite and S-video into component YCbCr. This decoder includes two 10-bit 30-MSPS A/D converters
(ADCs). Preceding each ADC in the device, the corresponding analog channel contains an analog circuit that
clamps the input to a reference voltage and applies a programmable gain and offset. A total of 10 video input
terminals can be configured to a combination of YPbPr, CVBS, or S-video video inputs.

Composite or S-video signals are sampled at 2⋅ the square-pixel or ITU-R BT.601 clock frequency, line-locked
alignment, and are then decimated to the 1⋅ pixel rate. CVBS decoding uses five-line adaptive comb filtering for both
the luma and chroma data paths to reduce both cross-luma and cross-chroma artifacts. A chroma trap filter is also
available. On CVBS and S-video inputs, the user can control video characteristics such as contrast, brightness,
saturation, and hue via an I

2C host port interface. Furthermore, luma peaking (sharpness) with programmable gain

is included, as well as a patented chroma transient improvement (CTI) circuit. The following output formats can be
selected: 20-bit 4:2:2 YCbCr or 10-bit 4:2:2 YCbCr. The TVP5147 decoder generates synchronization, blanking,
field, active video window, horizontal and vertical syncs, clock, genlock (for downstream video encoder
synchronization), host CPU interrupt and programmable logic I/O signals, in addition to digital video outputs. The
TVP5147 decoder includes methods for advanced vertical blanking interval (VBI) data retrieval. The VBI data
processor (VDP) slices, parses, and performs error checking on teletext, closed caption (CC), and othe r VBI data. A
built-in FIFO stores up to 11 lines of teletext data, and with proper host port synchronization, full-screen teletext
retrieval is possible. The TVP5147 decoder can pass through the output formatter 2⋅sampled raw luma data for
host-based VBI processing.
