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 su

19、ch as insulation barriers, insulation papers shields are properly installed. 3. After servicing, carry out the following leakage current checks to prevent the customer from being exposed to shock hazards. 1.1.1.Leakage Current Cold Check 1. Unplug the AC cord and connect a jumper between the two pro

20、ngs on the plug. 2. Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on the equipment such as screwheads, connectors, control shafts, etc. When the exposed metallic part has a return path to the chassis, the reading should be between

21、 1M and 5.2M. When the exposed metal does not have a return path to the chassis, the reading must be 1.1.2.Leakege Current Hot Check 1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check. 2. Connect a 1.5k, 10 watts resistor, in parallel with a 0.15F cap

22、acitors, between each exposed metallic part on the set and a good earth ground such as a water pipe, as shown in Figure 1. 3. Use an AC voltmeter, with 1000 ohms/volt or more sensitivity, to measure the potential across the resistor. 4. Check each exposed metallic part, and measure the voltage at ea

23、ch 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 volts RMS. A leakage current tester (Simpson Model 229 or equivalent) may be used to make the hot checks, leakage current must not exceed 1/2 milliamp. In

24、 case a measurement is outside of the limits specified, there is a possibility of a shock hazard, and the equipment should be repaired and rechecked before it is returned to the customer. Figure 1 1.2.Before Use Be sure to disconnect the mains cord before adjusting the voltage selector. Use a minus(

25、-) screwdriver to set the voltage selector (on the rear panel) to the voltage setting for the area in which the unit will be used. (If the power supply in your area is 110V 127V or 220V 240V, set to the “110V 127V or 220V 240V” position.) Note that this unit will be seriously damaged if this setting

26、 is not made correctly. (There is no voltage selector for some countries, the correct voltage is already set.) 1.3.Caution For Fuse Replacement 1.4.Before Repair and Adjustment Disconnect AC power to discharge unit AC Capacitors as such (C5701, C5703, C5704, C5705, C5706, C5707, C5708) through a 10

27、, 10 W resistor to ground. Caution: DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices. After repairs are completed, restore power gradually using a variac, to avoid overcurrent. 5 Current consumption at AC 110127 V / 220240 V, 50/60 Hz in

28、 NO SIGNAL mode volume minimal should be 500 mA. 1.5.Protection Circuitry The protection circuitry may have operated if either of the following conditions are noticed: No sound is heard when the power is turned on. Sound stops during a performance. The function of this circuitry is to prevent circui

29、try damage if, for example, the positive and negative speaker connection wires are “shorted”, or if speaker systems with an impedance less than the indicated rated impedance of the amplifier are used. If this occurs, follow the procedure outlines below: 1. Turn off the power. 2. Determine the cause

30、of the problem and correct it. 3. Turn on the power once again after one minute. Note: When the protection circuitry functions, the unit will not operate unless the power is first turned off and then on again. 1.6.Safety Parts Information Safety Parts List: There are special components used in this

31、equipment which are important for safety. These parts are marked by in the Schematic Diagrams,Exploded View & Replacement Parts List. It is essential that these critical parts should be replaced with manufacturers specified parts to prevent shock, fire or other hazards. Do not modify the original de

36、amaged easily by static electricity. Such components commonly are called Elec- trostatically 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

37、incidence of component damage caused by electrostatic 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
