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,soifyou touch internal metal parts when the set is energized, youmaygetanelectricshock.Avoidgettingan electricshock,byusinganisolatingtransformer and wearing gloves when servicing while the set is energized,orbyunpluggingthepowercordwhen replacing parts, for example. (2) Therearehighvoltagepartsinside.Handlewith extra care when the set is energized. Caution concerning disassembly and assembly! Through great care is taken when parts were manufacturedfromsheetmetal,theremaybeburrson theedgesofparts.Theburrscouldcauseinjuryiffingers are moved across them in some rare cases. Wear gloves toprotectyourhands. Use only designated parts! Thesetspartshavespecificsafetyproperties(fire resistance,voltageresistance,etc.).Besuretouseparts which have the same properties for replacement. The burrs have the same properties. In particular, for the importantsafetypartsthatareindicatedbythez mark on schematic diagrams and parts lists, be sure to use the designated parts. Be sure to mount parts and arrange the wires as they were originally placed! Forsafetyseasons,somepartsusetapes,tubesorother insulatingmaterials,andsomepartsaremountedaway from the surface of printed circuit boards. Care is also takenwiththepositionsofthewiresbyarrangingthem andusingclampstokeepthemawayfromheatingand highvoltageparts,sobesuretoseteverythingbackas itwasoriginallyplaced. 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 resistancevaluebetweentheinplugandtheexternally exposedmetalparts(antennaterminal,headphones terminal,inputterminal,etc.)is1Morgreater.Ifitis less, the set must be inspected and repaired.

Be sure to replace them with the parts which have the designated part number. (1)Schematicdiagrams .Indicatedbythez mark. (2)Partslists .Indicatedbythez mark. The use of parts other than the designated parts could cause electric shocks,firesorotherdangerous situations.
