Safety Precaution

PRECAUTIONS DURINGSERVICING

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 lightning flash with arrowhead symbol,within an equilateral triangle, is intended toalert the user to the presence of uninsulated“dangerous voltage” within the product’s enclosure that may be of sufficient magnitude toconstitute a risk of electric shock to persons.

The exclamation point within an equilateraltriangle is intended to alert the user to thepresence of important operating andmaintenance (servicing) instructions in theliterature accompanying the appliance.

CAUTION: TO REDUCE THE RISK OFELECTRIC SHOCK, DO NOT REMOVE COVER(OR BACK). NO USER-SERVICEABLE PARTSINSIDE. REFER SERVICING TO QUALIFIEDSERVICE PERSONNEL ONLY.

CAUTION

RISK OF ELECTRIC SHOCKDO NOT OPEN

MAKE YOUR CONTRIBUTIONTO PROTECT THE

ENVIRONMENTUsed 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 INSTRUCTIONThe 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.

Page 3: Aoc Pdp-4294lv1 Pdp4294lv1 Service Manual

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.

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.

Good earth groundsuch as the waterpipe, conductor,etc.

Place this probeon each exposedmetallic part

Basic operation of Plasma Display

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

2. When the ON signal from Key Switch or Remote Receiver is detected, Micro Processorwill send ON Control signals to Power. Then Power sends (5Vsc, 9Vsc, 24V and RLYON, 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 signalsinput, them will be amplified by Audio AMP and transmitted to Speakers.

3. If some abnormal signals are detected (for example: over volts, over current, overtemperature and under volts), the system will be shut down by Power off.

Preliminary

General DescriptionPW171 is a highly integrated “system-on-a-chip” that interfaces analog, digital, and video inputs in virtually any format to a flat panel monitor or multimedia display. PW171 is pin-compatible with the PW364.

An embedded SDRAM frame buffer and memory controller perform frame rate conversion. Computer images from VGA to UXGA at almost any refresh rate can be resized to fit on a fixed-frequency target display device with any resolution up to UXGA with full 24-bit color.

PW171 includes advanced second-generation image scaling that provides completely programmable, horizontal and vertical image scaling.

PW171 also includes advanced second-generation sync decoding which provides full support for a wide variety of sync types. This includes interlaced, progressive, sync-on-green, and TMDS DE (Data Enable) only.

PW171 ImageProcessor supports NTSC or PAL video data with a 4:3 aspect ratio and 16:9 aspect ratio sources, such as DVD or HDTV. Nonlinear scaling and separate horizontal and vertical scalers allow these inputs to be resized optimally for the native resolution and aspect ratio of the display device.

PW171 uses an integrated PLL to synchronize the display interface timing to the input timing. This requires only a single external crystal to generate all necessary clocks for the system.

An integrated OSD controller provides bit-mapped based OSDs with 16 colors from a 64K color palette. The OSD controller supports transparent and translucent functions.

PW171 provides a Pulse Width Modulation (PWM) output for low cost backlight or audio control.

With reference source code and an on-chip microprocessor, manufacturers can develop feature-rich products with rapid time-to-market. Programmable features include the user interface, custom start-up screen, all automatic imaging features, and special screen effects.

PW171 incorporates new features while maintaining backward compatibility with the PW264 and PW364 ImageProcessors.
