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 followingleakagecurrent checks to prevent the customerfrom being exposedto shock hazards.
4.When conducting repairs and servicing, donot attempt to modify the equipment, its parts or its materials.
5.When wiring units (withcables, flexible cables or lead wires) are supplied asrepair parts and only one wire or some of thewires havebeenbroken or disconnected, do not attempt torepair or re-wire the units. Replace the entire wiring unit instead.
6.When conducting repairs andservicing, donot twist the Faston connectors but plugthemstraight in or unplug themstraightout.
1.1.1.Leakage Current Cold Check
1.Unplug the AC cord and connect a jumper between thetwo prongs on the plug.
2.Measure the resistance value, with an ohmmeter,between the jumpered AC plug and each exposedmetallic cabinet part on the equipment such asscrewheads, connectors, control shafts, etc. When theexposed metallic part has areturnpathto the chassis, thereading should be8.5Mohm to 13Mohm.When the exposed metal does not have a return path to the chassis, thereading must be .
1.1.2.Leakage Current Hot Check (SeeFigure 1.)
1.Plug the AC cord directly into the AC outlet. Do not usean isolation transformer for this check.
2.Connect a 1.5kohm, 10 watts resistor, in parallel with a
0.15μF capacitors, between each exposed metallic parton the set and a good earth ground such as a water pipe,as shown in Figure 1.
3.Use an AC voltmeter, with 1000 ohms/volt or moresensitivity, to measure the potential across theresistor.
4.Check each exposed metallic part, and measure thevoltage at each point.
5.Reverse the AC plug in the AC outlet and repeat each ofthe abovemeasurements.
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. Incase ameasurement is outside of the limits specified, there isapossibility of a shock hazard, and the equipment shouldbe repaired and rechecked before it is returned to thecustomer.

2Warning
2.1.Prevention of Electrostatic Discharge (ESD) to Electrostatically
Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called
Electrostatically Sensitive (ES) Devices. Examples of typicalES devices are integrated circuits and some field-effect transistors andsemiconductor [chip] components. Thefollowing techniques should be used to help reducethe incidence of component damagecaused by electrostatic discharge(ESD).
1.Immediately before handling any semiconductor component orsemiconductor-equippedassembly, drain off any ESDon yourbody bytouching a known earth ground. Alternatively,obtainand wear a commercially available discharging ESD wrist strap,which should be removedfor 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 onaconductive surface such asaluminum foil, toprevent electrostatic charge builduporexposure of theassembly.
3.Useonly a grounded-tip solderingiron tosolder or unsolder ES devices.
4.Use only an anti-staticsolder removal device. Some solder removal devices not classified as [anti-static (ESD protected)] cangenerate electrical chargesufficient 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. (Mostreplacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil orcomparable conductive material).
7.Immediately before removing the protective material fromtheleads of a replacement ES device, touch the protective materialto the chassis or circuit assembly into which the device will beinstalled.
Caution
Besurenopower is appliedto the chassis or circuit, and observe all other safety precautions.
8.Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as thebrushingtogether of your clothes fabric or the lifting 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 it’s manufacture dueto environmental conservation issues. For service and repair work, we’dsuggest the use of Pb freesolder as well, althoughPb solder may beused.
PCBs manufactured using leadfree solder will have the PbF within a leaf Symbol PbFstamped on the back of PCB.
Caution
•Pb free solder has a higher melting pointthan standard solder. Typically the melting point is 50 ~ 70 °F (30~40°C) higher. Pleaseuse a high temperature solderingiron and set it to 700 ± 20°F(370 ± 10 °C).
•Pb free solder will tend tosplash when heatedtoo high (about 1100 °F or 600 °C).If you must use Pb solder, please completely remove all of the Pb free solderon the pins or solder area before applying Pbsolder. If this is not practical, besureto heat the Pb free solder until it melts, beforeapplying 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)

Purpose:
To find the possible failure point where in LCD Panel or Printed Circuit Boardwhen the abnormal picture is displayed.
How to Enter:
While pressing [VOLUME ( - )] button ofthe main unit, press [YELLOW] buttonof the remotecontrol three times within 2 seconds.
How to Exit:
Switchoff the powerwith the [POWER] button onthe main unit or the [POWER] button onthe remote control.
How to confirm:
If the abnormal picture is displayed, go intoLCDPanel test mode to display the several test patterns.And then, judge by the following method.Still abnormal picture is displayed: The cause must be in LCD Panel.Normal picture is displayed: The cause must beinA board.
Remarks:
Thetest patternis createdby the circuit in LCD Panel.In LCD Panel test mode, this test pattern is displayed unaffectedbysignal processing for RF or input signal.If thenormal picture is displayed, LCD Panel must be okay and thecause of failure must beinA board.
