1 SAFETY PRECAUSIONS1.1. GENERAL GUIDELINES1. 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 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, shield, and isolation 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 prevent the customer from being exposed to shock hazards. Caution: Use a separate Isolation Transformer for this unit when servicing.

not exceed 1/2 mA. In case a measurement is outside of the limits specified, there is a possibility of shock hazard, and the receiver should be repaired and rechecked before it is returned to the customer.

Figure 1

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 when replacing the Lamp Unit. 3. The lamp emits small amounts of UV-Radiation. Avoid direct-eye contact by covering the Lamp and wearing the UV cut protective glass. 4. The high pressure lamp involves a risk of explosion.

1.2.

LEAKAGE CURRENT COLD CHECK

1. Unplug the AC cord and connect a jumper between the two prongs on the plug. 2. For physically operated power switches, turn power on. Otherwise skip step 2. 3. Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on the receiver, such as screwheads, connectors, etc. When the exposed metallic part has a return path to the chassis, the reading should be between 1 M and 12 M. When the exposed metal does not have a return path to the chassis, the reading must be infinity.

1.3.

LEAKAGE CURRENT HOT CHECK

Figure 2

1. Plug the AC cord directly into the AC outlet. Do not use a isolation transformer for this check. 2. Connect a 1.5 k, 10 W resistor, in parallel with a 0.15 F capacitor, between each exposed metallic part on the set and a good earth ground, as shown in Figure 1. 3. Use an AC voltmeter, with 1 k/V or more sensitivity, to measure the potential across the resistor. 4. Check each exposed metallic part, and measure the voltage at each point. 5. Reverse the AC plug in the AC outlet and repeat each of the above 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 3

2 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 Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor "chip" components. The following techniques should be used to help reduce the incidence of component damage caused 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 as aluminum 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 antistatic solder removal device. Some solder removal devices not classified as "antistatic (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 comparable conductive material). 7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to 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 harmless 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 to damage an ES device).

REPLACEMENT OF LAMPLamp Time Reset Procedure:Be sure to reset the Lamp time to "0" after replacing the new Lamp. 1. Plug in the AC Cord, and turn on the power by pressing the POWER button. 2. Press and hold the VOLUME DOWN button on the unit and the PIP key on the remote together for over 5 seconds in power on condition. When the reset is finished, the display as shown in Fig. 51 appears and the LAMP LED goes out.

Lamp Replacement Procedure:1. Press the POWER button on the remote to turn off the power. 2. Wait for about 1 minute until the cooling fan stops. Note: The lamp cooling fan will continue to operate for about 1 minute after the power is turned off. Do not unplug the AC Cord from the outlet until the fan has stopped. Avoid interrupting the power by using circuit breakers or switchable power strips. 3. After the cooling fan has stopped, unplug the AC Cord from the outlet. Note: Please wait more than one hour before replacing the lamp. [ Forced cooling function ] If you need to replace the lamp more urgently: The Projection display has a forced cooling feature. After the POWER button is turned OFF, and sometime during about the first minute of the normal cooling fan operation, press the VOLUME UP button on the unit and CH UP key on the remote at the same time for more than 5 seconds. The cooling fan will operate for about 10 minutes. (LAMP LED will flash 5 times every 5 second and POWER LED will flash red for 10 minutes.) 4. Remove the Front Cover Unit from the latches. 5. Remove the Lamp Cover by loosening the Screw.

Fig. 5-1 Note: 1. The unit will detect when the Lamps end of life is approaching and the following message will be displayed. And the LAMP indicator light will be lit when the Lamps end of life is approaching.

Lamp Cover Screw

Fig. 5-2 2. Influences of frequent lighting, continuous light use for over 24 hours, the number of times lit, the length of time between lightings, etc. may shorten lamp life. (Because of this, we recommend having a replacement lamp on hand.) WARNING: The lamp could rupture if dropped and lamp fragments could cause injury. Because the lamp unit is hot immediately after its use, touching it may cause burns. Please allow the lamp to cool before handling or replacing the lamp unit. If replacement of the lamp unit becomes necessary during the operation of the Device Display, follow the procedure to turn off the power 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 your finger can cause the glass to weaken where touched and the bulb can crack or explode.

Fig. 5-3 6. Loosen the Screw on the Lamp. Then, pull the Lamp. Note: Because the Lamp may still be hot, use caution when handling.Lamp Screw

Fig. 5-4 7. Install the new Lamp, and tighten the Screw. 8. Install the Lamp Cover securely, and tighten the Screw. 9. Install the Front Cover Unit. Note: After replacing the Lamp, use caution to reset the Lamp time.14
