1 SAFETY PRECAUSIONS1.1. GENERAL GUIDELINES 1. For continued safety, no modification of any circuit should
be attempted. 2. Disconnect AC Plug before disassembling this unit. 3. It is advisable to use an isolation transformer in the AC
supply before servicing. 4. When servicing, observe the original lead dress. If a short
circuit is found, replace all parts which have beenoverheated or damaged by the short circuit.
5. After servicing, see to it that all the protective devices suchas insulation barriers, insulation papers, shield, andisolation R-C combinations etc. are properly installed.
6. After servicing, be sure to restore the wires, leads,insulation barriers, shields, etc.
7. After servicing, make the leakage current checks to preventthe customer from being exposed to shock hazards.
Caution:Use a separate Isolation Transformer for this unit whenservicing.
1.2. LEAKAGE CURRENT COLDCHECK
1. Unplug the AC cord and connect a jumper between the twoprongs on the plug.
2. For physically operated power switches, turn power on.Otherwise skip step 2.
3. Measure the resistance value, with an ohmmeter, betweenthe jumpered AC plug and each exposed metallic cabinetpart on the receiver, such as screwheads, connectors, etc.When the exposed metallic part has a return path to thechassis, the readingshouldbebetween 1 MΩ and 12 MΩ.When the exposed metal does not have a return path to thechassis, the reading must be infinity.
1.3. LEAKAGE CURRENT HOTCHECK
1. Plug the AC cord directly into the AC outlet.Do not use a isolation transformer for this check.
2. Connect a 1.5 kΩ, 10 W resistor, in parallel with a 0.15 µFcapacitor, between each exposed metallic part on the setand a good earth ground, as shown in Figure 1.
3. Use an AC voltmeter, with 1 kΩ/V or more sensitivity, tomeasure 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 V RMS.A leakage current tester (Simpson Model 229 equivalent)may be used to make the hot checks. Leakage current must
not exceed 1/2 mA. In case a measurement is outside ofthe limits specified, there is a possibility of shock hazard,and thereceivershouldbe repaired and rechecked before itis returned to the customer.
Figure 1
1.4. UV-PRECAUTION 1. Be sure to disconnect the AC Plug when replacing the
lamp. 2. Since the lamp reaches a very high temperature during its
operation, wait until it has completely cooled off whenreplacing the Lamp Unit.
3. The lamp emits small amounts of UV-Radiation.Avoid direct-eye contact by covering the Lamp and wearingthe UV cut protective glass.
4. The high pressure lamp involves a risk of explosion.

2 PREVENTION OFELECTROSTATICDISCHARGE (ESD) TOELECTROSTATICALLYSENSITIVE (ES) DEVICES
Some semiconductor (solid state) devices can be damagedeasily by static electricity. Such components commonly arecalled Electrostatically Sensitive (ES) Devices. Examples oftypical ES devices are integrated circuits and some field-effecttransistorsandsemiconductor"chip" components. The followingtechniques should be used to help reduce the incidence ofcomponent damage caused by electro static discharge (ESD). 1. Immediately before handling any semiconductor
component or semiconductor-equipped assembly, drain offany ESD on your body by touching a known earth ground.Alternatively, obtain and wear a commercially availabledischarging ESD wrist strap,whichshouldbe removed forpotential shock reasons prior to applying power to the unitunder test.
2. After removing an electrical assembly equipped with ESdevices, place the assembly on a conductive surface suchas aluminum foil, to prevent electrostatic charge buildup orexposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolderES devices.
4. Use only an antistatic solder removal device. Some solderremoval devices not classified as "antistatic (ESDprotected)" can generate electrical charge sufficient todamage ES devices.
5. Do not use freon-propelled chemicals. These can generateelectrical charges sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protectivepackage until immediately before you are ready to install it.(Most replacement ES devices are packaged with leadselectrically shorted together by conductive foam, aluminumfoil or comparableconductivematerial).
7. Immediately before removing the protective material fromthe leads of a replacement ES device, touch the protectivematerial to the chassis or circuit assembly into which thedevice will be installed.CAUTION :
Be sure no power is applied to the chassis or circuit, andobserve all other safety precautions.
8. Minimize bodily motions when handling unpackagedreplacement ES devices. (Otherwise harmless motion suchas the brushing together of your clothes fabric or the liftingof your foot from a carpeted floor can generate staticelectricity (ESD)sufficienttodamage an ES device).

Fig. 5-2
2. Influences of frequent lighting, continuous light use forover 24 hours, the number of times lit, the length of timebetween lightings, etc. may shorten lamp life. (Becauseof this, we recommend having a replacement lamp onhand.)
WARNING:• The high-pressure lamp could explode if not properly
handled and lamp fragments could cause injury.• Because the temperature of the lamp unit is elevated
immediately after its use, touching it may cause burns.Please allow the lamp to cool before handling or replacingthe lamp unit.
• Wear gloves and safety eyeglasses when replacing thelamp unit.
• If replacement of the lamp unit becomes necessary duringthe operation of the TV, follow the procedure to turn off thepower and wait until the lamp unit cools completely.
Cautions for Lamp Unit Replacement:• Do not disassemble the Lamp.• The lamp may be hot. Be careful when handling. Wear
gloves.• Under no circumstance should you touch the actual bulb.
At this high operating temperature the natural oil on yourfinger can cause the glass to weaken where touched andthe bulb can crack or explode.
