Safety precautions
1. Instructions
Be sure to switch off the power supply before replacing or welding any components or
inserting/plugging in connection wire Anti static measures to be taken (throughout the entire
production process!):
a) Do not touch here and there by hand at will;
b) Be sure to use anti static electric iron;
c) It’s a must for the welder to wear anti static gloves.
Please refer to the detailed list before replacing components that have special safety
requirements.
Do not change the specs and type at will.
2. Points for attention in servicing of LCD
2.1 Screens are different from one model to another and therefore not interchangeable. Be sure to
use the screen of the original model for replacement.
2.2 The operation voltage of LCD screen is 700-825V. Be sure to take proper measures in
protecting yourself and the machine when testing the system in the course of normal operation or
right after the power is switched off. Please do not touch the circuit or the metal part of the module
that is in operation mode. Relevant operation is possible only one minute after the power is
switched off.
2.3 Do not use any adapter that is not identical with the TV set. Otherwise it will cause fire or
damage to the set.
2.4 Never operate the set or do any installation work in bad environment such as wet bathroom,
laundry, kitchen, or nearby fire source, heating equipment and devices or exposure to sunlight etc.
Otherwise bad effect will result.
2.5 If any foreign substance such as water, liquid, metal slices or other matters happens to fall into
the module, be sure to cut the power off immediately and do not move anything on the module
lest it
should cause fire or electric shock due to contact with the high voltage or short circuit.
2.6 Should there be smoke, abnormal smell or sound from the module, please shut the power off
at
once. Likewise, if the screen is not working after the power is on or in the course of operation, the
power must be cut off immediately and no more operation is allowed under the same condition.
2.7 Do not pull out or plug in the connection wire when the module is in operation or just after the
power is off because in this case relatively high voltage still remains in the capacitor of the driving
circuit. Please wait at least one minute before the pulling out or plugging in the connection wire.
2.8 When operating or installing LCD please don’t subject the LCD components to bending,
twisting
or extrusion, collision lest mishap should result.
2.9 As most of the circuitry in LCD TV set is composed of CMOS integrated circuits, it’s necessary
to pay attention to anti statics. Before servicing LCD TV make sure to take anti static measure and
ensure full grounding for all the parts that have to be grounded.
2.10 There are lots of connection wires between parts behind the LCD screen. When servicing or
moving the set please take care not to touch or scratch them. Once they are damaged the screen
Attention: This service manual is only for service personnel to take reference with. Before
servicing please read the following points carefully.

would be unable to work and no way to get it repaired.
If the connection wires, connections or components fixed by the thermotropic glue need to
Page 4
disengage when service, please soak the thermotropic glue into the alcohol and then pull them
out
in case of dagmage.
2.11 Special care must be taken in transporting or handling it. Exquisite shock vibration may lead
to
breakage of screen glass or damage to driving circuit. Therefore it must be packed in a strong
case
before the transportation or handling.
2.12 For the storage make sure to put it in a place where the environment can be controlled so as
to
prevent the temperature and humidity from exceeding the limits as specified in the manual. For
prolonged storage, it is necessary to house it in an anti-moisture bag and put them altogether in
one
place. The ambient conditions are tabulated as follows:
2.13 Display of a fixed picture for a long time may result in appearance of picture residue on the
screen, as commonly called “ghost shadow”. The extent of the residual picture varies with the
maker of LCD screen. This phenomenon doesn’t represent failure. This “ghost shadow” may
remain
in the picture for a period of time (several minutes). But when operating it please avoid displaying
still picture in high brightness for a long time.
3. Points for attention during installation
3.1 The front panel of LCD screen is of glass. When installing it please make sure to put it in
place.
3.2 For service or installation it’s necessary to use specified screw lest it should damage the
screen.
3.3 Be sure to take anti dust measures. Any foreign substance that happens to fall down between
the screen and the glass will affect the receiving and viewing effect
3.4 When dismantling or mounting the protective partition plate that is used for anti vibration and
insulation please take care to keep it in intactness so as to avoid hidden trouble.
3.5 Be sure to protect the cabinet from damage or scratch during service, dismantling or
mounting.

Pin list and alternative functionsSTx7101
7.2Alternative functions
To impr ove flexibility and to allow the STx7101 to fit into differ ent set-top box application
architectures, the input and output signals from some of the peripherals and functions are not
directly connected to t he pi ns of the device. Instead they are assigned t o t he alternative functi on
inputs and outputs of a PIO port bit, or an I/O pi n. This scheme allows the pins to be configured
with their default function if the associated input or output is not required in that particular
application.
Some pins have several alternative functions, for inputs and/or outputs. In Table 6 to Table 11,
the different alternative functions are listed under the table headings Alt 1, Alt 2, to Alt n.
Inputs connec ted to the alternative function input are permanently connected to the input pin.
The output signa l from a peripheral is only connected when the PIO bit is configured into either
push-pull or open drain driver alternative function mode.
Some alternative function signals are available on more than one PI O port.

MPEG-2/MPEG-4 DVB Decoder (STi7101)
1.4.General Description
The STi7101 is a new generation, high-definition IDTV / set-top box / DVD decoder chip, and
provides very high performance for low-cost HD systems. STx7101 includes an H.264 video
decoder for new, low bit rate applications. Based on the Omega2 (STBus) architecture, this
system-on-chip is a full back-end processor for digital terrestrial, satellite, cable, DSL and IP
client high-definition set-top boxes, compliant with ATSC, DVB, DIRECTV, DCII,
OpenCable and ARIB BS4 specifications. It includes all processing for DVD applications.
The STx7101 demultiplexes, decrypts and decodes HD or SD video streams with associated
multi-channel audio. Video is output to two independently formatted displays: a full resolution
display intended for a TV monitor, and a downsampled display intended for a VCR or DVD-R.
Connection to a TV or display panel can be analog through the DACs, or digital through a copy
protected DVI/HDMI. Composite outputs are provided for connection to the VCR with
Macrovision protection. Audio is output with optional PCM mixing to an S/PDIF interface,
PCM interface, or through integrated stereo audio DACs. Digitized analog programs can also
be input to the STx7101 for reformatting and display. The STx7101 includes a graphics
rendering and display capability with a 2D graphics accelerator, three graphics planes and a
cursor plane. A dual display compositor provides mixing of graphics and video with
independent composition for each of the TV and VCR/DVD-R outputs. The STx7101 includes
a stream merger to allow seven different transport streams from different sources to be merged
and processed concurrently. Applications include DVR time-shifted viewing of a terrestrial
program, while acquiring an EPG/data stream from a satellite or cable front end.
The flexible descrambling engine is compatible with required standards including DVB, DES,
AES and Multi2. The STx7101 embeds a 266 MHz ST40-202 CPU for applications and device
control. A dual DDR1 SDRAM memory interface is used for higher performance, to allow the
video decoder the required memory bandwidth for HD H.264 and sufficient bandwidth for the
CPU and the rest of the system. A second memory bus is also provided for flash memory,
storing resident software, and for connection of peripherals. This bus also has a high speed
synchronous mode that can be used to exchange data between two STx7101 devices. This can
be used to connect a second STx7101 as a co-decoder for a dual TV STB application. A harddisk drive (HDD) can be connected either to the serial ATA interface, or as an expansion drive
through the USB 2.0 port.

The STv0362 is a single-chip demodulator using coded orthogonal frequency division
multiplexing (COFDM) and is intended for digital terrestrial receivers using compressed
video, sound and data services. It converts IF or baseband differential signals to MPEG-2
format by processing OFDM carriers.
The STv0362 is fully compliant with the DVB-T specification (ETS 300 744) and NorDig
Unified specification. The chip implements all the functions to convert the signals from the
IF or direct conversion tuner, to produce the MPEG-2 transport stream output; in terms of
IF tuner configuration, the chip is compatible with the popular STV0360/STV0361. The
STv0362 offers improved performance over the STV0360 with respect to:
channel estimation and correction,
an extended CRL frequency and TRL timing offset,
additional features such as:
o synchronization for echo outside GI,
o impulse noise rejection,
o PLL allowing 4 MHz quartz usage.
The STv0362 processes 2, 4 and 8 K modes and integrates two A/D converters capable
of handling up to 64 QAM carriers in a direct IF or zero IF sampling architecture. This
eliminates the need for an external downconverter. A 12-bit ADC, intended for RF signal
strength indication, eliminates the need for external components when using wide-band
AGC tuners. In addition to the demodulation and forward error correction (FEC) functions
required for recovery of the QAM modulated bit streams with very low BER, the chip also
includes several features that give easy and immediate access to various quality
monitoring parameters or lock status. The STv0362 also provides delayed AGC and a
noise-free I2C bus dedicated to tuner control, which facilitate the design of high quality
integrated receiver decoders. The STv0362 outputs an error-corrected MPEG-2 transport
stream that complies with the DVB common interface format with programmable data
clock frequency.
Page 39
The STv0362 features the full DVB-T and DVB-H standards framing structure, channel
coding and modulation. The symbol, timing and carrier recovery loops are fully digital and
sized with regard to the state-of-the-art RF down-converting devices.
The STv0362 is compatible with direct conversion tuners featuring two differential ADC for
I and Q channels. The tuner baseband power is controlled by a classic AGC loop, and the
radio frequency level is monitored by a dedicated single-ended 8-bit ADC. It is
recommended the RF power is left under the tuner’s control, but it can be derived from
baseband power by a dedicated power split algorithm. If required, the tuner serial I2C bus
can be isolated by the STv0362 I2C bus repeater.
The terrestrial DVB-T network can be subjected to several interference sources which are
the neighboring digital and analog channels, as well as the in-band analog channels. The
STv0362 cancels these interference sources as well removing the effects of impulse
noise. The channel equalization is capable of static and dynamic echo cancelling even in
severe urban environments. The embedded algorithms are enhanced to cope with out-ofguard interval echoes; specific channel quality monitoring is available for acquisition and
survey. The specific power handling constraints are primarily addressed by both
technology and clock rate management. The efficiency of channel acquisition and reacquisition, minimizes power consumption.

DVB-C DEMODULATOR – STV0297E
7.1General Desription
The STV0297E is a complete single-chip QAM (quadrature amplitude modulation)
demodulation and FEC (forward error correction) solution that performs sampled IF to
transport stream (MPEG-2 or MPEG-4) block processing of QAM signals. It is intended for
the digital transmission of compressed television, sound, and data services over cable. It
is fully compliant with ITU-T J83 Annexes A/C or DVB-C specification bitstreams (ETS
300 429, “Digital broadcasting systems for television, sound and data services – Framing
structure, channel coding and modulation - Cable Systems”). It can handle square (16,
64, 256-QAM) and non-square (32, 128-QAM) constellations. Japanese DBS systems
require a transport stream multiplex frame (TSMF) layer to carry digital signals over cable
systems. When the recovered transport stream is a multiplex frame, the STV0297E postprocesses it to extract a single transport stream. Automatic detection of the TSMF layer is
provided. The chip integrates an analog-to-digital converter that delivers the required
performance to handle up to 256-QAM signals in a direct IF sampling architecture, thus
eliminating the need for external downconversion.
