If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the set is defective. Be sure to test for leakage current with the AC plug in both polarities, in addition, when the sets power is in each state (on,offandstandbymode),ifapplicable.CAUTION Please heed the following cautions and instructions during servicing and inspection. Heed the cautions!Cautions which are delicate in particular for servicing are labeled on the cabinets, the parts and the chassis, etc. Be sure to heed these cautions and the cautions described in the handling instructions. Cautions concerning electric shock!(1) AnACvoltageisimpressedonthisset,soifyoutouch internal metal parts when the set is energized, youmaygetanelectricshock.Avoidgettinganelectricshock,byusinganisolatingtransformerand wearing gloves when servicing while the set is energized,orbyunpluggingthepowercordwhenreplacing parts, for example.(2) Therearehighvoltagepartsinside.Handlewithextra care when the set is energized.

Make a safety check after servicing!Check that all screws, parts and wires removed or disconnected when servicing have been put back in their original positions, check that no serviced parts have deteriorate the area around. Then make an insulation check on the external metal connectors and between the blades of the power plug, and otherwise check that safetyisensured.(Insulationcheckprocedure)Unplug the power cord from the power outlet, disconnect the antenna, plugs, etc., and on the power. Using a 500V insulation resistance tester, check that the insulation resistancevaluebetweentheinplugandtheexternallyexposedmetalparts(antennaterminal,headphonesterminal,inputterminal,etc.)is1Morgreater.Ifitisless, the set must be inspected and repaired.Manyoftheelectricandthestructuralpartsusedinthesethavespecialsafetyproperties.Inmostcasesthesepropertiesaredifficulttodistinguishbysight,andtheuseofreplacementpartswithhigherratings(ratedpowerandwithstandvoltage)doesnotnecessarilyguaranteethatsafetyperformancewillbepreserved.Partswithsafetypropertiesareindicatedasshownbelowonthewiring diagrams and the parts list in this service manual.
