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

apparatus have special safety-related

characteristics.

These characteristics are offer passed

unnoticed by visual spection and the protection

afforded by them cannot necessarily be obtained

by using replacement components rates for a

higher voltage, wattage, etc.

The replacement parts which have these

special safety characteristics are identified by

marks on the schematic diagram and on the parts

list.

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.

9. Must be sure that the ground wire of the AC

inlet is connected with the ground of the

apparatus properly.

Good earth ground
such as the water
pipe, conductor,
etc.

Basic operation of LCD-TV

1. After turning on power switch, power board sends 5Vst-by Volt to Micro
Processor IC waiting for ON signals from Key Switch or Remote Receiver.

2. When the ON signal from Key Switch or Remote Receiver is detected, Micro
Processor will send ON Control signals to Power. Then Power sends (5Vsc,
18Vsc, 24V and RLY ON, Vs ON) to PCBs working. This time VIF will send
signals to display back light, 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.

LCD basic display theory.

When an electrical field is applied to the LC planes, the LC molecules re-align
themselves so that they are parallel to the electrical field. This electrical process
is known as twisted nematic field effect or TNFE. In this alignment, polarized
light is not twisted as it passes through the LC material (see Diagram 3A and
3B). If the front polarizer is oriented perpendicular to the rear polarizer, light will
pass through the energized display but will be blocked by the rear polarizer. An
LCD in this form is acting as a light shutter.
Displays with variable characters are created by selectively etching away the
conductive surface that was originally deposited on the glass. Etched areas
become the display’s background; unetched areas become the display’s
characters.

Diagram 3A. The “off” state of a TN LCD-the LC molecules form a twist and therefore
cause polarized light to twist as it passes through.

Diagram 3B. The “on” state-the electrical field re-aligns the LC molecules so they do
not twist the polarized light.

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.

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.

Capable of processing Vertical Blanking Interval (VBI)
data from both fields of the video frame in data, the Z86229
Line 21 Decoder offers a feature-rich solution for any tele­vision or set-top application. The robust nature of the
Z86229 helps the 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 datastream can consist of data fromseveral 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

C serial bus. The recovered XDS data packet is further

the I
defined in the EIA–608 specification. The on-chip XDS fil­ters in the Z86229 are fully programmable, enabling recov­ery of only 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 SHEET MSP 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 processin g,
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 34x0G can handle ver y 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.

Product Specification

1. General Description

The LC420W02 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
Lamp(CCFL) backlight system. The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive type display operating in the normally black mode. It has a 42.0 inch diagonally measured
active display area with WXGA resolution (768 vertical by 1366 horizontal pixel array).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes.
Gray scale or the luminance of the sub-pixel color is determined with a 8-bit gray scale signal for each dot,
thus presenting a palette of more than 16.7M(true) colors.
It has been designed to apply the 8-bit 1-port LVDS interface.
It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,
high color depth and fast response time are important.

9. Precautions

Please pay attention to the followings when you use this TFT LCD module.

9-1. Mounting Precautions

(1) You must mount a module using holes arranged in four corners or four sides.
(2) You should consider the mounting structure so that uneven force (ex. Twisted stress) is not applied to the

module. And the case on which a module is mounted should have sufficient strength so that external
force is not transmitted directly to the module.

(3) Please attach the surface transparent protective plate to the surface in order to protect the polarizer.

Transparent protective plate should have sufficient strength in order to the resist external force.
(4) You should adopt radiation structure to satisfy the temperature specification.
(5) Acetic acid type and chlorine type materials for the cover case are not desirable because the former

generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break
by electro-chemical reaction.

(6) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB

pencil lead. And please do not rub with dust clothes with chemical treatment.

Do not touch the surface of polarizer for bare hand or greasy cloth.(Some cosmetics are detrimental

to the polarizer.)
(7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like

chamois soaks with petroleum benzine. Normal-hexane is recommended for cleaning the adhesives
used to attach front / rear polarizers. Do not use acetone, toluene and alcohol because they cause
chemical damage to the polarizer.

(8) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes

deformations and color fading.

(9) Do not open the case because inside circuits do not have sufficient strength.

9-2. Operating Precautions

(1) The spike noise causes the mis-operation of circuits. It should be lower than following voltage :

V=±200mV(Over and under shoot voltage)

(2) Response time depends on the temperature.(In lower temperature, it becomes longer.)
(3) Brightness depends on the temperature. (In lower temperature, it becomes lower.)

And in lower temperature, response time(required time that brightness is stable after turned on) becomes

longer.

(4) Be careful for condensation at sudden temperature change. Condensation makes damage to polarizer or

electrical contacted parts. And after fading condensation, smear or spot will occur.
(5) When fixed patterns are displayed for a long time, remnant image is likely to occur.
(6) Module has high frequency circuits. Sufficient suppression to the electromagnetic interference shall be

done by system manufacturers. Grounding and shielding methods may be important to minimized the

interference.
(7) Please do not give any mechanical and/or acoustical impact to LCM. Otherwise, LCM can’t be operated

its full characteristics perfectly.

(8) A screw which is fastened up the steels should be a machine screw.

(if not, it causes metallic foreign material and deal LCM a fatal blow)

(9) Please do not set LCD module on its edge.

9-3. Electrostatic Discharge Control

Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make certain that
treatment persons are connected to ground through wrist band etc. And don’t touch interface pin directly.

9-4. Precautions for Strong Light Exposure

Strong light exposure causes degradation of polarizer and color filter.

9-5. Storage

When storing modules as spares for a long time, the following precautions are necessary.

(1) Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the temperature

between 5°C and 35°C at normal humidity.

(2) The polarizer surface should not come in contact with any other object.

It is recommended that they be stored in the container in which they were shipped.

9-6. Handling Precautions for Protection Film

(1) The protection film is attached to the bezel with a small masking tape.

When the protection film is peeled off, static electricity is generated between the film and polarizer.
This should be peeled off slowly and carefully by people who are electrically grounded and with well ion­blown equipment or in such a condition, etc.

(2) When the module with protection film attached is stored for a long time, sometimes there remains a very

small amount of glue still on the bezel after the protection film is peeled off.

(3) You can remove the glue easily. When the glue remains on the bezel surface or its vestige is recognized,

please wipe them off with absorbent cotton waste or other soft material like chamois soaked with normal­hexane.
