    1 Safety Precautions

    1.1. General Guidelines1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or

    damaged by the short circuit.

    2. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly

    installed.

    3. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.4. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or

    damaged by the short circuit.

    5. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly

    installed.

    6. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.

    1.2. Touch-Current Check1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check.

    2. Connect a measuring network for touch currents between each exposed metallic part on the set and a good earth ground

    such as a water pipe, as shown in Figure 1.

    3. Use Leakage Current Tester (Simpson 228 or equivalent) to measure the potential across the measuring network.

    4. Check each exposed metallic part, and measure the voltage at each point.

    5. Reserve the AC plug in the AC outlet and repeat each of the above measure.

    6. The potential at any point (TOUGH CURRENT) expressed as voltage U1and U2, does not exceed the following values:

    For a. c.: U1= 35 V (peak) and U2= 0.35 V (peak);

    For d. c.: U1= 1.0 V,

    Note:The limit value of U2= 0.35 V (peak) for a. c. and U1= 1.0 V for d. c. correspond to the values 0.7 mA (peak) a. c. and 2.0

    mA d. c.

    The limit value U1= 35 V (peak) for a. c. correspond to the value 70 mA (peak) a. c. for frequencies greater than 100 kHz.

    7. In case a measurement is out of the limits specified, there is a possibility of a shock hazard, and the equipment should be

    repaired and rechecked before it is returned to the customer.

    2 Warning

    2.1. Prevention of Electrostatic Discharge (ESD) to Electrostatically

    Sensitive (ES) DevicesSome semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec-

    trostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and

    semiconductor [chip] components. The following techniques should be used to help reduce the incidence of component damage

    caused by electrostatic discharge (ESD).

    1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your

    body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap,

    which should be removed for potential shock reasons prior to applying power to the unit under test.

    2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as alumi-

    num foil, to prevent electrostatic charge buildup or exposure of the assembly.

    3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.

    4. Use only an anti-static solder removal device. Some solder removal devices not classified as [anti-static (ESD protected)] can

    generate electrical charge sufficient to damage ES devices.

    5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices.

    6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most

    replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or compara-

    ble conductive material).7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material

    to the chassis or circuit assembly into which the device will be installed.

    CautionBe sure no power is applied to the chassis or circuit, and observe all other safety precautions.

    8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise ham less motion such as the brush-

    ing together of your clothes fabric or the l ifting of your foot from a carpeted floor can generate static electricity (ESD) sufficient

    to damage an ES device).

    2.2. About lead free solder (PbF)Note: Lead is listed as (Pb) in the periodic table of elements.

    In the information below, Pb will refer to Lead solder, and PbF will refer to Lead Free Solder.

    The Lead Free Solder used in our manufacturing process and discussed below is (Sn+Ag+Cu).

    That is Tin (Sn), Silver (Ag) and Copper (Cu) although other types are available.

    This model uses Pb Free solder in its manufacture due to environmental conservation issues. For service and repair work, wed

    suggest the use of Pb free solder as well, although Pb solder may be used.

    PCBs manufactured using lead free solder will have the PbF within a leaf Symbol PbFstamped on the back of PCB.

    Caution Pb free solder has a higher melting point than standard solder. Typically the melting point is 50 ~ 70 F (30~40 C) higher. Please

    use a high temperature soldering iron and set it to 700 20 F (370 10 C).

    Pb free solder will tend to splash when heated too high (about 1100 F or 600 C).

    If you must use Pb solder, please completely remove all of the Pb free solder on the pins or solder area before applying Pb sol-

    der. If this is not practical, be sure to heat the Pb free solder until it melts, before applying Pb solder.

    After applying PbF solder to double layered boards, please check the component side for excess solder which may flow onto the

    opposite side. (see figure below)

    Suggested Pb free solderThere are several kinds of Pb free solder available for purchase. This product uses Sn+Ag+Cu (tin, silver, copper) solder. How-

    ever, Sn+Cu (tin, copper), Sn+Zn+Bi (tin, zinc, bismuth) solder can also be used.

    8 Measurements and Adjustments

    8.1. Adjustment Procedure

    8.1.1. Driver Set-up

    8.1.1.1. Item / Preparation1. Input a white signal to plasma video input.

    2. Set the picture controls as follows.

    Picture menu : Dynamic

    PNR : OFF

    Aspect : 16 : 9

    Caution1. First perform Vsus adjustment.

    2. Confirmation of Vscn voltage should be performed after

    confirmation of Vad adjustment.

    When Vad= -140V, Voltage of Vscn is 5V 4V.

    8.1.1.2. AdjustmentsAdjust driver section voltages referring the panel data on the

    panel data label.

    Check or adjust the following voltages with the multimeter.
