In case a measurement is outside of the limits specified, there is a possibility of shock hazard, and thereceivershouldbe repaired and rechecked before it is returned to the customer. 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 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. Figure 1 7. After servicing, make the leakage current checks to prevent the customer from being exposed to shock hazards. 1.4. 1. Be sure to disconnect the AC Plug when replacing the lamp. Caution: 2. Since the lamp reaches a very high temperature during its operation, wait until it has completely cooled off when replacing the Lamp Unit. Use a separate Isolation Transformer for this unit when servicing. 1.2. UV-PRECAUTION 3. The lamp emits small amounts of UV-Radiation. LEAKAGE CURRENT COLD CHECK 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. 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 readingshouldbebetween 1 MΩ and 12 MΩ. 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 kΩ, 10 W resistor, in parallel with a 0.15 µF 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 kΩ/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 PT-43LC14 / PT-50LC14 / PT-60LC14 2 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 typical ES devices are integrated circuits and some field-effect transistorsandsemiconductor"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,whichshouldbe 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 comparableconductivematerial). 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)sufficienttodamage an ES device). 4 PT-43LC14 / PT-50LC14 / PT-60LC14 3 ABOUT LEAD FREE SOLDER (PbF) 5 PT-43LC14 / PT-50LC14 / PT-60LC14 4 SERVICE NOTES LED INDICATIONS FOR ERROR CONDITION Each LED indication facilitates finding the cause of the error.
