  • 2.1.1. Leakage Current Cold Check 1. Unplug the AC cord and connect a jumper between the two

    prongs on the plug. 2. Measure the resistance value, with an ohmmeter, between

    the jumpered AC plug and each exposed metallic cabinetpart on the equipment such as screwheads, connectors,control shafts, etc. When the exposed metallic part has areturn path to the chassis, the reading should be between1Mohm and 5.2Mohm.When the exposed metal does not have a return path to

    the chassis, the reading must be .

    Figure 1

    2.1.2. Leakage Current Hot Check (SeeFigure 1.)

    1. Plug the AC cord directly into the AC outlet. Do not use anisolation transformer for this check.

    2. Connect a 1.5kohm, 10 watts resistor, in parallel with a0.15F capacitors, between each exposed metallic part onthe set and a good earth ground such as a water pipe, asshown in Figure 1.

    3. Use an AC voltmeter, with 1000 ohms/volt or moresensitivity, to measure the potential across the resistor.

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

    5. Reverse the AC plug in the AC outlet and repeat each of theabove measurements.

    6. The potential at any point should not exceed 0.75 voltsRMS. A leakage current tester (Simpson Model 229 orequivalent) may be used to make the hot checks, leakagecurrent must not exceed 1/2 milliamp. In case ameasurement is outside of the limits specified, there is apossibility of a shock hazard, and the equipment should berepaired and rechecked before it is returned to thecustomer.

    2 Safety Precautions2.1. General Guidelines 1. 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.

  • 3 Prevention of Electro Static Discharge (ESD) toElectrostatically Sensitive (ES) Devices

    Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are calledElectrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors andsemiconductor "chip" components. The following techniques should be used to help reduce the incidence of component damagecaused by electro static 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 asaluminum 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 comparableconductive material).

    7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective materialto the chassis or circuit assembly into which the device will be installed.Caution

    Be 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 brushing

    together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) sufficient todamage an ES device).

  • 4 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, wedsuggest 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 PbF stamped 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 Pbsolder. 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 ontothe 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.However, Sn+Cu (tin, copper), Sn+Zn+Bi (tin, zinc, bismuth) solder can also be used.

    Procedure Remarks Ensure aging is adequate.

    Make sure the front panel to be used on the final set is fitted.

    Make sure a color signal is not being shown before adjustment.

    Put the color analyzer where there is little color variation.

    1. Output a white balance pattern.

    2. Check that the color temperature is Cool.

    3. Set to serviceman mode, WB-ADJ.

    4. Set R-CUT G-CUT B-CUT the values written in table 1.

    5. Attach the sensor of color analyzer to he center of highlight window.

    6. Fix G drive at C0h and adjust B-DRV and R-DRV so x, y value of color analyzer

    become the Color temperature High in table 2.

    7. Increase RGB together so the maximum drive value in RGB becomes FCh. That is,

    set ALL DRIVE to FCh.

    8. Set color temperature to Normal.

    9. Set R-CUT G-CUT B-CUT the values written in table 1.

    10. Attach the sensor of color analyzer to the center of highlight window.

    11. Fix G drive at C0h and adjust B-DRV and R-DRV so x, y value of color analyzer

    become the Color temperature Mid in table 2.

    12. Increase RGB together so the maximum drive value in RGB becomes FCh. That is,

    set ALL DRIVE to FCh.

    13. Set color temperature to Warm.

    14. Set R-CUT G-CUT B-CUT the values written in table 1.

    15. Attach the sensor of color analyzer to the center of highlight window.

    16. Fix G drive at C0h and adjust B-DRV and R-DRV so x, y value of color analyzer

    become the Color temperature Low in table 2.

    17. Increase RGB together so the maximum drive value in RGB becomes FCh. That is,

    set ALL DRIVE to FCh.

    18. Set color temperature to Cool.

    [ adjustment of Normal Warm by data shift from Cool adjust. ]

    For Normal Warm adjustment, set values that the adjusted value of Cool

    plus the figures wrote below.
