ESDDWARNUNGAlle ICs und viele andere Halbleiter sindempfindlich gegenber elektrostatischenEntladungen (ESD).Unsorgfltige Behandlung im Reparaturfall kandie Lebensdauer drastisch reduzieren.Veranlassen Sie, dass Sie im Reparaturfall berein Pulsarmband mit Widerstand verbundensind mit dem gleichen Potential wie die Massedes Gertes.Bauteile und Hilfsmittel auch auf dieses gleichePotential halten.NLWAARSCHUWINGAlle ICs en vele andere halfgeleiders zijngevoelig voor electrostatische ontladingen(ESD).Onzorgvuldig behandelen tijdens reparatie kande levensduur drastisch doen verminderen.Zorg ervoor dat u tijdens reparatie via eenpolsband met weerstand verbonden bent methetzelfde potentiaal als de massa van hetapparaat.Houd componenten en hulpmiddelen ook opditzelfde potentiaal.IAVVERTIMENTOTutti IC e parecchi semi-conduttori sonosensibili alle scariche statiche (ESD).La loro longevit potrebbe essere fortementeridatta in caso di non osservazione della pigrande cauzione alla loro manipolazione.Durante le riparazioni occorre quindi esserecollegato allo stesso potenziale che quello dellamassa dellapparecchio tramite un braccialettoa resistenza.Assicurarsi che i componenti e anche gli utensilicon quali si lavora siano anche a questopotenziale.“Pour votre scurit, ces documentsdoivent tre utiliss par des spcia-listes agrs, seuls habilits rparervotre appareil en panne”.GBSafety regulations require that the set be restored to its originalcondition and that parts which are identical with those specified,be used.NLVeiligheidsbepalingen vereisen, dat het apparaat bij reparatie inzijn oorspronkelijke toestand wordt teruggebracht en dat onderdelen,identiek aan de gespecificeerde, worden toegepast.FLes normes de scurit exigent que lappareil soit remis ltatdorigine et que soient utiliss les pices de rechange identiques celles spcifies.DBei jeder Reparatur sind die geltenden Sicherheitsvorschriften zubeachten. Der Original zustand des Gerts darf nicht verndert werden;fr Reparaturen sind Original-Ersatzteile zu verwenden.I Le norme di sicurezza esigono che lapparecchio venga rimessonelle condizioni originali e che siano utilizzati i pezzi di ricambioidentici a quelli specificati.After servicing and before returning set to customer perform aleakage current measurement test from all exposed metal parts toearth ground to assure no shock hazard exist. The leakage currentmust not exceed 0.5mA.CLASS 1LASER PRODUCT3122 110 03420GBWarning !Invisible laser radiation when open.Avoid direct exposure to beam.SVarning !Osynlig laserstrlning nr apparaten r ppnad och sprrenr urkopplad.

Use anAC voltmeter, having 5000 per volt or more sensitivity.Connect a 1500 10W resistor,paralleled by a 0.15uF150V AC capacitor between a knomn good earth ground(water pipe, conduit, etc.) and all exposed metal parts ofcabinet (antennas, handle bracket, metal cabinetscrewheads, metal overlays, control shafts, etc.).SAFTY PRECAUTIONSLEAKAGE CURRENT CHECKMeasure the AC voltage across the 1500 resistor.The test must be conducted with the AC switch on andthen repeated with the AC switch off. The AC voltageindicated by the meter may not exceed 0.3V.A readingexceeding 0.3V indicates that a dangerous potentialexists, the fault must be located and corrected.Repeat the above test with the DVD VIDEO PLAYERpower plug reversed.NEVER RETURN A DVD VIDEO PLAYER TO THECUSTOMER WITHOUT TAKING NECESSARYCORRECTIVE ACTION.READING SHOULD NOT EXCEED 0.3VDVD VIDEO PLAYERAC OUTLETAC VOLTMETERTest all exposed metal.Voltmeter Hook-up for Leakage Current Check0.15uF 150V AC150010W(5000 per voltor more sensitivity)Good earth groundsuch as a water pipe,conduit, etc.The lightning flash with arrowhead symbol, within anequilateral triangle, is intended to alert the user to thepresence of uninsulated dangerous voltage within theproducts enclosure that may be of sufficient magnitude toconstitute a risk of electric shock to persons.The exclamation point within an equilateral triangle isintended to alert the user to the presence of importantoperating and maintenance (servicing) instructions in theliterature accompanying the appliance.2-3 3-1 3-1 BLOCK DIAGRAM 4-1 4-1 WIRING DIAGRAM 5-1 5-1 CIRCUIT DIAGRAM- POWER BOARD 5-2 5-2 CIRCUIT DIAGRAM - MAIN BOARD 6-1 6-1 LAYOUT DIAGRAM - TOP VIEW 6-2 6-2 LAYOUT DIAGRAM - BOTTOM VIEW 7-1 7-1 EXPLODE VIEW DIAGRAM
