  • Page 2 SAFETY PRECAUTIONS GENERAL GUIDELINES 1. When servicing, observe the original lead dress. If a short / circuit is found, replace all parts which have been over-heated 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.
  • Page 3 The resistance value must be more than 5M Figure1 LEAKAGE CURRENT HOT CHECK (See Figure 1) 1. Plug the AC cord directly into the AC outlet. / Do not use an isolation transformer for this check. 2. Connect a 1.5k , 10W resistor, in parallel with a 0.15 capacitor, between each exposed metallic part on the set an a good earth ground such as a water pipe, as shown in Figure1.
  • Page 4 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. / Alternatively, obtain and wear a commercially available discharging wrist trap device, which should be removed for potential shock reasons prior to applying power to the unit under test.
  • Page 5 X-RADIATION WARNING 1. The potential source of X-radiation in EVF sets is the High Voltage section and the picture tube. 2. When using a picture tube test jig for service, ensure that jig is capable of handling 10kV without causing x-radiation. Note : It is important to use an accurate periodically calibrated high voltage meter.
