    Safety Precaution

    PRECAUTIONS DURINGSERVICING

    1. In addition to safety, other parts andassemblies 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 wires3) 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 uninsulateddangerous voltage within the products enclo

    sure 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 inthe 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 voltageof the picture tube before handling. The picture

    tube is a vacuum and if broken, the glass will

    explode.

    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 givento 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 electricalshock. 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 0.15F 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 ground

    such as the waterpipe, conductor,

    etc.

    Place this probe

    on each exposedmetallic part

    Basic operation of Plasma Display

    1. After turning on power switch, PSU board sends 5Vst-by Volt to Main IC MT8202 waiting

    for ON signals from Key Switch or Remote Receiver.

    2. When the ON signal from Key Switch or Remote Receiver is detected, MT8202 will send

    RLY ON and VS ON signals to PSU B/D. Then PSU B/D sends 5Vsc, 9Vsc, 24V toPCBs working. This time CONTROL Board will send signals to Panel by Z/Y SUS

    Board, OSD on the panel and display available signal. 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.

    Design

    1) This product may be damaged if it is subject to excessive stresses (such as excessive voltage, current, or

    temperature). The absolute maximum ratings specify the limits of these stresses, and system design must ensure

    that none of the absolute maximum ratings are exceeded.

    2) The recommended operating conditions are conditions in which the normal operation of this product is

    guaranteed. All the rated values of the electrical specifications are guaranteed within these conditions. Always

    use the product within the range of the recommended operating conditions. Otherwise, the reliability of the

    product may be degraded. Use of the product with a combination of parameters, conditions, or logic not

    specified in the specifications of this product is not guaranteed. If intending to use the product in such a way, be

    sure to consult LGE in advance.

    3) This product emits near infrared rays (800 to 1000nm) that may cause the remote controllers of other electric

    products to malfunction. To avoid this, use an infrared absorption filter and thoroughly evaluate the system and

    environment.

    Product Specification of PDP Module

    4) This product uses high-voltage switching and a high speed clock. A system using this product should be

    designed so that it does not affect the other systems, and should be thoroughly evaluated.

    5) The materials which contain sulfur are forbidden to use, because they may damage PDP module.

    6) This product has a glass display surface. Design your system so that excessive shock and load are not applied to

    the glass. Exercise care that the vent at the corner of the glass panel is not damaged. If the glass panel or vent is

    damaged, the product is inoperable.

    7) There are some exposed components on the rear panel of this product. Touching these components may cause an

    electric shock.

    8) This product uses a high voltage. Design your system so that any residual voltage in this product is dissipated

    quickly when power is turned off, observing the specifications.

    9) This product uses heat-emitting components. Take the heat emitted by these components into consideration

    when designing your system. If the product is used outside the specified temperature range, it may malfunction.

    10) This product uses a high voltage and, because of its compact design, components are densely mounted on the

    circuit board. If dust collects on these components, it can cause short-circuiting between the pins of the

    components and moisture can cause the insulation between the components to break down, causing the product

    to malfunction.

    11) Regulations and standards on safety and electromagnetic interference differ depending on the country. Design

    your system in compliance with the regulations and standards of the country for which your system is intended.

    12) To obtain approval under certain safety standards (such as UL and EN), a filter that passes a shock test must befitted over the glass surface of the finished product. In addition, it must be confirmed that the level of UV

    emissions is within the range specified by such standards.

    13) If this product is used as a display board to display a static image, image sticking occurs. This means that the

    luminance of areas of the display that remain lit for a long time drops compared with the luminance of areas that

    are lit for a shorter time, causing uneven luminance across the display. The degree to which this occurs is in

    proportion to the luminance at which the display is used. To prevent this phenomenon, therefore, avoid static

    images as much as possible and design your system so that it is used at a low luminance, by reducing signal level

    difference between bright area and less bright area through signal processing.

    14) Within the warranty period, general faults that occur due to defects in components such as ICs will be rectifiedby LGE without charge. However, IMAGE STICKING is not included in the warranty. Repairs due to the other

    faults may be charged for depending on responsibility for the faults.

    15) In case of AC PDP driving mechanism, Because the brightness of output is not always proportional to input

    signals. Therefore the non-linearity of gray can occasionally be observed in certain gray levels as well as

    Contour and Error Diffusion Noise can be appeared when a dark picture is on the screen especially. These are

    phenomena that can be observed on the PDP driving mechanism. With simple adjustment to picture brightness

    control, these can be reduced considerably.

    16) Because of the need to control the power consumption on the PDP driving mechanism, the APL(Average Picture

    Level) mode was equipped. Thus, as the picture on the screen changes, there can be slightly switched in

    brightness. This also is a phenomenon that can be observed on the PDP driving mechanism.

    17) This product is designed to LGEs Standard quality grade. If you wish to use the product for applications

    outside the scope of the Standard quality grade, be sure to consult LGE in advance to assess the technological

    feasibility before starting to design your system.

    USE

    1) Because this product uses a high voltage, connecting or disconnecting the connectors while power is supplied to

    the product may cause malfunctioning. Never connect or disconnect the connectors while the power is on.

    Immediately after power has been turned off, a residual voltage remains in the product. Be sure to confirm thatthe voltage has dropped to a sufficiently low level.

    2) Watching the display for a long time can tire the eyes. Take a break at appropriate intervals.

    3) PDP s brightness and contrast ratio is lower than that of the CRT. The picture is dimmer with surrounding light

    and better for viewing in dark condition.

    4) Do not cover or wrap the product with a cloth or other covering while power is supplied to the product.

    5) Before turning on power to the product, check the wiring of the product and confirm that the supply voltage is

    within the rated voltage range. If the wiring is wrong or if a voltage outside the rated range is applied, the

    product may malfunction or be damaged.

    6) Do not store this product in a location where temperature and humidity are high. This may cause the product to

    malfunction. Because this product uses a discharge phenomenon, it may take time to light (operation may be

    delayed) when the product is used after it has been stored for a long time. In this case, it is recommended to light

    all cells for about 2hours (aging).

    7) If the glass surface of the display becomes dirty, wipe it with a soft cloth moistened with a neutral detergent. Do

    5. IMAGE STICKING CHARACTERISTICS

    Image Sticking

    The fluorescent substance used in the plasma module loses its brightness with the lapse of lighting time. This

    deterioration in brightness appears to be a difference in brightness in relation to the surroundings, and comes to

    be recognized as image sticking.

    In other words, the image sticking is defined as follows: when the same pattern (of the fixed display) is

    displayed for a long time, a difference in brightness is caused around the lighting area and non-lighting area due

    to deterioration in the fluorescent substance.

    When the present pattern is changed over to another one, the boundary comes to be seen between the lighting

    area and non-lighting area due to difference in brightness in the pattern shown shortly before changeover. If this

    conditions is accumulated, the boundary or image sticking comes to be seen with the naked eyes.

    Secular change in brightness

    The life of brightness, defined as the reduction to half the initial level, is more than 25 thousand hours on average.

    Conditions: All white (100% white) input at an ambient temperature of 25C.

    However, this lifetime is not a guarantee value for life and brightness. It should be recognized simply as the data

    for reference.

    Warranty

    Image sticking and faults in brightness and picture elements are excluded from the warranty objects.

    Cause of deterioration in brightness

    A major possible cause of deterioration in brightness is damage in the fluorescent substance due to impact caused

    by ions generated at the time of plasma discharges.

    The relationship between integrated lighting time and brightness in this plasma module is described in the

    attached material. In particular, the deterioration in brightness tends to be accelerated up to 100 hours in the initialperiod. In the initial period, the fixed display of patterns particularly tends to cause image sticking. The practical

    value for image sticking is difficult in concrete numerals. As described below, you are advised to take proper

    measures to make the occurrence of image sticking as slow as possible.

    Practical value for Image sticking

    50/67

    Product Specification of PDP Module

    So long as there is the reduction of brightness in the fluorescent substance, it is impossible to avoid the

    occurrence of image sticking. Therefore, to relieve image sticking, we offer you a method of entering an imageinput that may ensure reluctance to the generation of the difference in brightness reduction among the displayed

    dots.

    The images from TV broadcasting involve a high rate of motion picture displays. Therefore, there is less chance

    of being a cause of difference in brightness reduction among the cells. Even when the fixed patterns are

    displayed, they generally last for a few minutes. Since the same pattern is less liable to be displayed, there is

    almost no influence toward image sticking.

    If the fixed patterns tend to be displayed for a long time, however, there occurs a substantial imbalance between

    the lighting and non-lighting areas, thus causing a difference in brightness as a result. In this document, we offer

    you some proposals of installation, paying attentions to the two points: the reduction of difference in brightness

    achieved by integrated lighting time leveling and the method of edge smearing to make image sticking hard to be

    discerned.

    The result from these proposals can, however, greatly depend on the contents of images and the operating

    environment. Therefore, we consider that it is essential to take the suitable measures in consideration of the

    customers operating environment.

    Example of Proposal 1: The display position is moved while the fixed display pattern is changed over, or it is

    scrolled during the display.

    Example of Proposal 2: If possible, a pattern of complementary color is incorporated (for integrated time

    leveling).

    Example of Proposal 3: The fixed pattern and the motion picture display are reciprocally exchanged, in order to

    minimize display period of the fixed pattern.

    Example of Proposal 4: During operation, the brightness of screen is suppressed as low as possible. For thedisplay patterns, characters are indicated not on the black ground (non-picture area) but on the colored ground

    (mixture of R, G, B recommended).
