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 following leakage current checks to prevent the customer from being exposed to shock hazards. 4. When servicing, observe the original lead dress.

After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed. 6. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards. 1.1.1. Leakage Current Cold Check 1.1.2. Leakage Current Hot Check (See 1. Unplug the AC cord and connect a jumper between the Figure 1.) two prongs on the plug. 1. Plug the AC cord directly into the AC outlet. Do not use 2. Measure the resistance value, with an ohmmeter, an isolation transformer for this check. between the jumpered AC plug and each exposed metal- 2. Connect a 1.5kohm, 10 watts resistor, in parallel with a lic cabinet part on the equipment such as screwheads, 0.15F capacitors, between each exposed metallic part connectors, control shafts, etc. When the exposed metal- on the set and a good earth ground such as a water pipe, lic part has a return path to the chassis, the reading as shown in Figure 1. should be 100 Mohm and over. 3. Use an AC voltmeter, with 1000 ohms/volt or more sensi- When the exposed metal does not have a return path to tivity, to measure the potential across the resistor. the chassis, the reading must be . 4. Check each exposed metallic part, and measure the volt- age 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
