1. Safety Precautions

1.1. General Guidelines

1. When servicing, observe the original lead dress. Ifashort circuit

isfound, replace all parts which have been overheated or

damaged bythe short circuit.

2. After servicing, see to itthat 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.

1.1.1. Leakage Current ColdCheck

1. Unplug the AC cord and connect ajumper between the two

prongs on the plug.

2. Measure the resistance value, with an ohmmeter, between the

jumpered AC plug and each exposed metalliccabinet part on the

equipment such as screwheads, connectors, control shafts, etc.

When the exposed metallicpart has areturn path to the chassis,

the reading shouldbe between 1M and 5.2M .

When the exposed metal does not have areturn path to the

chassis, the reading must be .

Figure 1

1.1.2. Leakage Current Hot Check (See Figure 1.)

1. Plug the AC cord directlyinto the AC outlet. Donot use an

isolation transformer for thischeck.

2. Connect a1.5k , 10 watts resistor, inparallel with a0.15 F

capacitors, between each exposed metallicpart on the set and a

good earth ground such as awater pipe, as shownin Figure 1.

3. Use an AC voltmeter, with 1000 ohms/voltor more sensitivity, to

measure the potential across the resistor.

4. Check each exposed metallicpart, and measure the voltage at

each point.

5. Reverse the AC plug inthe AC outlet and repeat each of the above

measurements.

6. The potential at anypoint shouldnot exceed 0.75 volts RMS. A

leakage current tester (Simpson Model 229 or equivalent) maybe

used to make the hot checks, leakage current must not exceed 1/2

milliamp. Incase ameasurement isoutside of the limits specified,

there isapossibilityof ashock hazard, and the equipment should

be repaired and rechecked before itisreturned to the customer.

2. Prevention of Electro Static Discharge (ESD) to

Electrostatically Sensitive (ES) Devices

Some semiconductor(solidstate) devices canbe damagedeasilybystatic electricity. Such

components commonlyare calledElectrostaticallySensitive (ES) Devices. Examples of typical

ES devices are integratedcircuits and some field-effect transistors and semiconductor"chip"

components. The following techniques shouldbe usedtohelpreduce the incidence of

component damage causedbyelectrostatic discharge (ESD).

1. Immediatelybefore handling anysemiconductor component or

semiconductor-equipped assembly, drainoff anyESDon your

bodybytouching aknownearth ground. Alternatively, obtainand

wear acommerciallyavailabledischarging ESDwrist strap, which

shouldbe removed for potential shock reasons prior to applying

power to the unitunder test.

2. After removing an electrical assemblyequipped with ES devices,

place the assemblyon aconductive surface such as alminum foil,

to prevent electrostaticcharge buildup or exposure of the

assembly.

3. Use onlyagrounded-tipsoldering iron to solder or unsolder ES

devices.

4. Use onlyan anti-staticsolder removal device. Some solder

removal devices not classified as "anti-static(ESDprotected)"

can generate electrical charge sufficient to damage ES devices.

5. Donot use freon-propelled chemicals. These can generate

electrical charges sufficient to damage ES devices.

6. Donot remove areplacement ES device from its protective

package until immediatelybefore you are readyto install it. (Most

replacement ES devices are packaged with leads electrically

shorted together byconductive foam, alminum foil or comparable

conductive material).

7. Immediatelybefore removing the protective material from the

leads of areplacement ES device, touch the protective material to

the chassisor circuitassemblyinto which the device will be

installed.

Caution

Besure no power isapplied to the chassisor circuit, and observe

all other safetyprecautions.

8. Minimize bodilymotions when handling unpackaged replacement

ES devices. (Otherwise hamless motion such as the brushing

together of your clothes fabricor the lifting of your foot from a

carpeted floor can generate staticelectricity(ESD)sufficient to

damage an ES device).

4. Self Check Function

4.1. SelfCheck

1. Self-Check isused to automaticallycheck the bus lines and

hexadecimal code of the TV set.

2. To get into the Self-Check mode press the Down( )button on

the customer controlsat the front of the set, at the same time

pressing the MENU button on the remote control, and the screen

will show :

3. Turn off the TV to reset JPEG Viewer mode after SELF-CHECK.

If the CCU ports have beencheckedand found tobe incorrect ornot locatedthen“--” will

appearinplace of “O.K.”.
