Safety Precaution
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
The lightning flash with arrowhead symbol,
within an equilateral triangle, is intended to
alert the user to the presence of uninsulated
“dangerous voltage” within the product’s enclo
sure that may be of sufficient magnitude to
constitute a risk of electric shock to persons.
CAUTION: TO REDUCE THE RISK OF
ELECTRIC SHOCK, DO NOT REMOVE COVER
(OR BACK). NO USER-SERVICEABLE PARTS
INSIDE. REFER SERVICING TO QUALIFIED
SERVICE PERSONNEL ONLY.
PRECAUTIONS DURING
SERVICING
1. In addition to safety, other parts and
assemblies are specified for conformance with
such regulations as those applying to spurious
radiation. These must also be replaced only
with specified replacements.
Examples: RF converters, tuner units, antenna
selection switches, RF cables, noise-blocking
capacitors, noise-blocking filters, etc.
2. Use specified internal Wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
3. Use specified insulating materials for hazardous
live parts. Note especially:
1) Insulating Tape
2) PVC tubing
3) Spacers (insulating barriers)
4) Insulating sheets for transistors
5) Plastic screws for fixing micro switches
4. When replacing AC primary side components
(transformers, power cords, noise blocking
capacitors, etc.), wrap ends of wires securely
about the terminals before soldering.
5. Make sure that wires do not contact heat
generating parts (heat sinks, oxide metal film
resistors, fusible resistors, etc.)
6. Check if replaced wires do not contact sharply
edged or pointed parts.
7. Make sure that foreign objects (screws, solder
droplets, etc.) do not remain inside the set.
The exclamation point within an equilateral
triangle is intended to alert the user to the
presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance.
MAKE YOUR CONTRIBUTION
TO PROTECT THE
ENVIRONMENT
Used batteries with the ISO symbol
for recycling as well as small accumulators
(rechargeable batteries), mini-batteries (cells) and
starter batteries should not be thrown into the
garbage can.
Please leave them at an appropriate depot.
WARNING:
Before servicing this TV receiver, read the
SAFETY INSTRUCTION and PRODUCT
SAFETY NOTICE.
SAFETY INSTRUCTION
The service should not be attempted by anyone
unfamiliar with the necessary instructions on this
apparatus. The following are the necessary
instructions to be observed before servicing.
1. An isolation transformer should be connected in
the power line between the receiver and the
AC line when a service is performed on the
primary of the converter transformer of the set.
2. Comply with all caution and safety related
provided on the back of the cabinet, inside the
cabinet, on the chassis or picture tube.
3. To avoid a shock hazard, always discharge the
picture tube's anode to the chassis ground
before removing the anode cap.
4. Completely discharge the high potential voltage
of the picture tube before handling. The picture
tube is a vacuum and if broken, the glass will
explode.
5. When replacing a MAIN PCB in the cabinet,
always be certain that all protective are
installed properly such as control knobs,
adjustment covers or shields, barriers, isolation
resistor networks etc.
6. When servicing is required, observe the original
lead dressing. Extra precaution should be given
to assure correct lead dressing in the high
voltage area.
7. Keep wires away from high voltage or high
tempera ture components.
8. Before returning the set to the customer,
always perform an AC leakage current check
on the exposed metallic parts of the cabinet,
such as antennas, terminals, screwheads,metal
overlay, control shafts, etc., to be sure the set
is safe to operate without danger of electrical
shock. Plug the AC line cord directly to the
AC outlet (do not use a line isolation
transformer during this check). Use an AC
voltmeter having 5K ohms volt sensitivity or
more in the following manner.
Connect a 1.5K ohm 10 watt resistor paralleled
by a 0.15µF AC type capacitor, between a
good earth ground (water pipe, conductor etc.,)
and the exposed metallic parts, one at a time.
Measure the AC voltage across the combination
of the 1.5K ohm resistor and 0.15 uF
capacitor. Reverse the AC plug at the AC
outlet and repeat the AC voltage measurements
for each exposed metallic part.
The measured voltage must not exceed 0.3V
RMS.
This corresponds to 0.5mA AC. Any value
exceeding this limit constitutes a potential
shock hazard and must be corrected
immediately.
The resistance measurement should be done
between accessible exposed metal parts and
power cord plug prongs with the power switch
"ON". The resistance should be more than
6M ohms.
AC VOLTMETER
PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this

Basic operation of Plasma Display
1. After turning on power switch, power board sends 5Vst-by Volt to Micro Processor
2. The micro Processor memorize the last state of Power, When the last state of
power is on or receive power on signal from local Key or Remote control, Micro
Processor will send on control signal to power. Then Power sends (5Vsc, 9Vsc,
24V and RLYON, Vs ON) to PCBs working. This time VIF will send signals to
display Image, OSD on the panel and start to search available signal sources.
If the audio signals input, them will be amplified by Audio AMP and transmitted to
Speakers.
3. If some abnormal signals are detected (for example: over volts, over current, over
temperature and under volts), the system will be shut down by Power off.

Product Specification
General Description
The PW181 ImageProcessor is a highly integrated
“system-on-a-chip” that interfaces computer graphics and
video inputs in virtually any format to a fixed-frequency flat
panel display.
Computer and video images from NTSC/PAL to WUXGA
at virtually any refresh rate can be resized to fit on a fixedfrequency target display device with any resolution up to
WUXGA. Video data from 4:3 aspect ratio NTSC or PAL
and 16:9 aspect ratio HDTV or SDTV is supported. Multiregion, nonlinear scaling allows these inputs to be resized
optimally for the native resolution of the display.
Advanced scaling techniques are supported, such as
format conversion using multiple programmable regions.
Three independent image scalers coupled with frame
locking circuitry and dual programmable color lookup
tables create sharp images in multiple windows, without
user intervention.
Embedded SDRAM frame buffers and memory controllers
perform frame rate conversion and enhanced video
processing completely on-chip. A separate memory is
dedicated to storage of on-screen display images and
CPU general purpose use.
Advanced video processing techniques are supported
using the internal frame buffer, including motion adaptive,
temporal deinterlacing with film mode detection. When
used in combination with the new third-generation scaler,
this advanced video processing technology delivers the
highest quality video for advanced displays.
Both input ports support integrated DVI 1.0 content
protection using standard DVI receivers.
A new advanced OSD Generator with more colors and
larger sizes supports more demanding OSD applications,
such as on-screen programming guides. When coupled
with the new, faster, integrated microprocessor, this OSD
Generator supports advanced OSD animation techniques.
Programmable features include the user interface, custom
start-up screen, all automatic imaging features, and
special screen effects.

GENERAL DESCRIPTION
The AD9883A is a complete 8-bit, 140 MSPS monolithic analog
interface optimized for capturing RGB graphics signals from
personal computers and workstations. Its 140 MSPS encode
rate capability and full power analog bandwidth of 300 MHz
supports resolutions up to SXGA (1280 × 1024 at 75 Hz).
The AD9883A includes a 140 MHz triple ADC with internal
1.25 V reference, a PLL, and programmable gain, offset, and
clamp control. The user provides only a 3.3 V power supply,
analog input, and Hsync and COAST signals. Three-state
CMOS outputs may be powered from 2.5 V to 3.3 V.
The AD9883A’s on-chip PLL generates a pixel clock from the
Hsync input. Pixel clock output frequencies range from 12 MHz to
140 MHz. PLL clock jitter is 500 ps p-p typical at 140 MSPS.
When the COAST signal is presented, the PLL maintains its
output frequency in the absence of Hsync. A sampling phase
adjustment is provided. Data, Hsync, and clock output phase
relationships are maintained. The AD9883A also offers full sync
processing for composite sync and sync-on-green applications.
A clamp signal is generated internally or may be provided by
the user through the CLAMP input pin. This interface is fully
programmable via a 2-wire serial interface.
Fabricated in an advanced CMOS process, the AD9883A is
provided in a space-saving 80-lead LQFP surface-mount plastic
package and is specified over the 0°C to 70°C temperature range.

Line 21 Decoder offers a feature-rich solution for any television or set-top application. The robust nature of the
Z86229 helpsthe device conform to the transmissionformat
defined in the Television Decoder Circuits Act of 1990, and
in accordance with the Electronics Industry Association
specification 608 (EIA–608).
The Line 21 data stream can consist of data from several data
channels multiplexed together. Field 1 consists of four data
channels: two Captions and two Texts. Field 2 consists of
five additional data channels: two Captions, two Texts, and
Extended Data Services (XDS). The XDS data structure is
defined in EIA–608. The Z86229 can recover and display
data transmitted on any of these nine data channels.
The Z86229 can recover and output to a host processor via
2

the I
defined in the EIA–608 specification. The on-chip XDS filters in the Z86229 are fully programmable, enabling recovery ofonly those XDS data packets selectedby the user.This
functionality allows the device to extract the required XDS
information with proper XDS filter setup for compatibility
in a variety of TVs, VCRs, and Set-Top boxes.
In addition, the Z86229 is ideally suited to monitor Line 21
video displayed in a PiP window for violence blocking,
CCD, and other XDS data services. A block diagram of the
Z86229 is illustrated in Figure 1.
PRELIMINARY DATA SHEETMSP 34x0G
Multistandard Sound Processor Family
Release Note: Revision bars indicate significant
changes to the previous edition. The hardware and
software description in this document is valid for
the MSP 34x0G version B8 and following versions.
1. Introduction
The MSP 34x0G family of single-chip Multistandard
Sound Processors covers the sound processing of all
analog TV-Standards worldwide, as well as the NICAM
digital sound standar ds. The full TV sound process ing ,
starting with analog sound IF signal-in, down to processed analog AF-out, is performed on a single chip.
Figure 1–1 shows a simplified functional block diagram
of the MSP 34x0G.
This new generation of TV sound processing ICs now
includes versions for processing the multichan nel television sound (MTS) signal conforming to the standard
recommended by the Broadcast Television Systems
Committee (BTSC). The DBX noise reduction, or alternatively, Micronas Noise Reduction (MNR) is performed alignment free.
Other processed standards are the Japanese FM-FM
multiplex standard (EIA-J) and the FM Stereo Radio
standard.
Current ICs have to perform adjustment procedu res in
order to achieve good stereo sepa ration for BTSC and
EIA-J. The MSP 34x0G has optimum stereo performance without any adjustments.
All MSP 34xxG versions are pin compatible to the
MSP 34xxD. Only minor modifications are necessary
to adapt a MSP 34xxD controlling software to the
MSP 34xxG. The MSP 34x0G further simplifies controlling software. St andard selection requi res a single
2
C transmission only.
I
The MSP 34x0G has built-in automatic functions: The
IC is able to detect the actual sound standard automatically (Automatic Standard Detection). Furthermore,
pilot levels and identification sign als can be evaluated
internally with subsequent switching between mono/
stereo/bilingual; no I
2
C interaction is necessar y (Auto-
matic Sound Selectio n) .
The MSP 3 4x0G can handle very high FM deviations
even in conjunction with NICAM processing. This is
especially impor tant for the introduction of NICAM in
China.
The ICs are produced in submicron CMOS technology.
The MSP 34x0G is available in the following packages:
PLCC68 (not intended for new design), PSDIP64,
PSDIP52, PQFP80, and PLQFP64.

Pericom Semiconductor’s PI5V series of mixed signal video
circuits are produced in the Company’s advanced CMOS
low-power technology, achieving industry leading performance.
The PI5V330 is a true bidirectional Quad 2-channel
multiplexer/demultiplexer that is recommended for both
RGB and composite video switching applications. The
VideoSwitch™ can be driven from a current output
RAMDAC or voltage output composite video source.
Low ON-resistance and wide bandwidth make it ideal for
video and other applications. Also this device has exceptionally high current capability which is far greater than most
analog switches offered today. A single 5V supply is all that
is required for operation.
The PI5V330 offers a high-performance, low-cost solution
to switch between video sources. The application section
describes the PI5V330 replacing the HC4053 multiplier and
buffer/amplifier.
The AT24C32/64 provides 32,768/65,536 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 4096/8192 words of 8 bits
each. The device’s cascadable feature allows up to 8 devices to share a common 2wire bus. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. The AT24C32/64 is
available in space saving 8-pin JEDEC PDIP, 8-pin JEDEC SOIC, 8-pin EIAJ SOIC,
and 8-pin TSSOP (AT24C64) packages and is accessed via a 2-wire serial interface.
In addition, the entire family is available in 5.0V (4.5V to 5.5V), 2.7V (2.7V to 5.5V),
2.5V (2.5V to 5.5V) and 1.8V (1.8V to 5.5V) versions.

2. Precaution
** To prevent the risks of unit damage, electrical shock and radiation, take the
following safety, service, and ESD precautions.
2-1 Handling Precautions for Plasma Display
PDP module use high voltage that is
dangerous to human. Before operating
PDP, always check the dust to prevent
circuit short. Be careful touching the
circuit device when power is on.
PDP module is sensitive to dust and
humidity. Therefore, assembling and
disassembling must be done in no dust
place.
PDP module has a lot of electric
devices. Service engineer must wear
equipment(for example , earth ring) to
prevent electric shock and working
clothes to prevent electrostatic.
PDP module use a fine pitch connector
which is only working by exactly
connecting with flat cable. Operator
must pay attention to a complete
connection when connector is
reconnected after repairing.
The capacitor’s remaining voltage in
the PDP module’s circuit board
temporarily remains after power is off.
Operator must wait for discharging of
remaining voltage during at least 1
minute.
2-2 Safety Precautions for Service (Handling, prevention of a electrical shock, measure
against power outage, etc)
( Safety Precautions )
Before replacing a board, discharge forcibly
The remaining electricity from board. To prevent the Logic circuit from being
When connecting FFC and TCPs to the
module, recheck that they are perfectly
connected.
To prevent electrical shock, be careful not
to touch leads during circuit operations.
damaged due to wrong working, do not
connect/disconnect signal cables during
circuit operations.

SamsungSDICo.Ltd.A/SManual Plasma Display Module
Do thoroughly adjustment of a voltage label
and voltage-insulation.
Before reinstalling the chassis and the
chassis assembly, be sure to use all
protective stuffs including a nonmetal
controlling handle and the covering of
partitioning type.
Caution for design change : Do not install
any additional devices to the module, and
do not change the electrical circuit design.
For example: Do not insert a subsidiary
audio or video connector. If you insert It, It
cause danger on safety. And, If you change
the design or insert, Manufactor guarantee
Examine carefully the cable status if it is
twisted or damaged or displaced. Do not
change the space between parts and circuit
board. Check the cord of AC power
preparing damage.
Product Safety Mark : Some of electric or
implement material have special
characteristics invisible that was related on
safety. In case of the parts are changed
with new one, even though the Voltage and
Watt is higher than before, the Safety and
Protection function will be lost.
The AC power always should be turned off,

will be not effect. .
If any parts of wire is overheats of damaged,
replace it with a new specified one
immediately, and identify the cause of the
problem and remove the possible
dangerous factors.
( Precaution when repairing ESD )
There is ESD which is easily damaged by
electrostatics.(for example Integrated circuit,
FET ) Electrostatic damage rate of product
will be reduced by the following technics
Check assembly condition of screw, parts
and wire arrangement after repairing.
Check whether the material around the
parts get damaged.

the antistatic wrist-belt and ring. ( It must be
operated after removing dust on it – It
comes under precaution of electric shock.)
Before handling semiconductor
parts/assembly, must remove positive
7/37
After removing ESD assembly, put on it with
protective material into contact with the
aluminum stuff on the conductive surface to
prevent charging.
Do not use chemical stuff using Freon. It
generates positive electric that can damage
ESD.
Must use a soldering device for ground-tip
when soldering or de-soldering ESD.
Must use anti-static solder removal device.
Most removal device do not have antistatic
which can charge a enough positive electric
enough damaging ESD.
Before removeing the protective material
from the lead of a new ESD, bring the
chassis or assembly that the ESD is to be
installed on.
When handing an unpacked ESD for
replacement, do not move around too much.
Moving (legs on the carpet, for example)
generates enough electrostatic to damage
the ESD.
Do not take a new ESD from the protective
case until the ESD is ready to be installed.
Most ESD have a lead, which is easily
short-circuited by conductive materials
(such as conductive foam and aluminum)
