1 Safety Precautions1.1. General Guidelines
1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated ordamaged by the short circuit.
2. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properlyinstalled.
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 U1 and 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 2.0mA 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 berepaired and rechecked before it is returned to the customer.

2 Warning2.1. 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 andsemiconductor [chip] components. The following techniques should be used to help reduce the incidence of component damagecaused by electrostatic discharge (ESD).
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on yourbody 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 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 brush-
ing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) sufficientto damage an ES device).4
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, 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. Pleaseuse 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 theopposite 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.5

1. Remove all connector between SC board and SU/SD board to isolate SC board from both SU and SD board electrically.Note: The board will be damaged if all connector is not removed (for example; remove connector only for SU board and stayconnecting with SD board. The board will be damaged.)
2. Connect SC jig to connector SC50 at left bottom side of SC board3. Turn of the TV/Display Unit and confirm the power LED blinking.
LED blinking: Possible cause of failure is in SC boardNo LED blinking (Lighting or no lighting): Possible cause of failure is in SU or SD board
4. After inspection, turn off the TV/Display Unit and wait a few minutes to discharge.5. Remove SC jig from SC board.
Remark: This SC jig can be used for all 2009 Plasma TV and Plasma Display.19
