Warning2:Anyelectrolyticcapacitorwiththe wrongpolaritywillexplode,

Precaution

Theserviceinstructionsare printedonthecabinet,and shouldbefollowedbyanyservicepersonnel,

Makesureto unplugtheAC powercordfromthe power sourcebeforestartinganyrepairs, (a) Removeorre-installpartsor assemblies, (b) Disconnecttheelectricplugor connector,if any, (c)Connectthetest partin parallelwiththeelectrolytic capacitor.

Somepartsareplacedata higherpositionthanthe printedboard.Insulatedtubesortapesare usedfor this purpose.Theinternalwiringis clampedusingbucklesto avoidcontactwithheatemittingparts,Thesepartsare installedbackto theiroriginalposition.

Aftertherepair,makesuretocheckif thescrews,parts or cablesare properlyinstalled.Makesurenodamageis causedtotherepairedpartand itssurroundings,

Checkfor insulationbetweenthebladeofthe AC plug andthatof anyconductivematerials(i,e,themetal panel,inputterminal,earphonejack,etc),

1-3Static Electricity Precautions

Somesemi-conductive("solidstate")devicesare vulnerableto staticelectricity.Thesedevicesareknown as ESD.ESDincludestheintegratedcircuitandthefield effecttransistor.To avoidanymaterialsdamagefrom

electrostaticshock,followtheinstructionsdescribed below.

Removeany staticelectricityfromyour bodyby connectingthe earthgroundbeforehandlingany semi-conductivepartsor ass'ys.Alternatively,weara dischargeablewrist-belt. (Makesuretoremoveanystaticelectricitybefore connectingthe powersource- this isa safetyinstruction foravoidingelectricshock)

Removethe ESDass'yand placeiton a conductive surfacesuchas aluminumfoilto preventaccumulating staticelectricity.

Donot use anyFreon-basedchemicals. Suchchemicalswillgeneratestaticelectricitythat causesdamagetotheESD.

5. Useonlygrounded-tipironsfor solderingpurposes.

Useonlyanti-staticsolderremovaldevices. Mostsolderremovaldevicesdonotsupportan

anti-staticfeature.A solderremovaldevicewithoutan anti-staticfeaturecan storeenoughstaticelectricityto

causedamageto the ESD.

DonotremovetheESDfromthe protectiveboxuntilthe replacementis ready.MostESD replacementsare

coveredwithlead,whichwillcausea shorttotheentire unitdueto the conductivefoam,aluminumfoilor other

conductivematerials.

RemovetheprotectivematerialfromtheESD replacementleadimmediatelyafterconnectingitto the chassisor circuitass'y.

TakeextremecautioninhandlinganyuncoveredESD replacements.Actionssuchasbrushingclothesorlifting yourlegfromthecarpetfloorcan generateenoughstatic electricitytodamagethe ESD.

1-4 Installation Precautions

Precaution

Forsafetyreasons,morethan twopeopleare required forcarryingtheproduct.

Keepthepowercordawayfromanyheatemitting devices,as a meltedcoveringmaycausefireorelectric

shock.

Wheninstallingthe product,makesureto keepit away fromthewall (morethan10cm/4inches)forventilation purposes.

Poorventilationmaycausean increasein theinternal temperatureof the product,resultinginashortened componentlife anddegradedperformance.

Bendtheexternalantennacablewhen connectingitto theproduct.Thisis a measuretoprotectitfrombeing exposedto moisture.Otherwise,itmaycausea fireor

electricshock.

Makesuretoturnthepoweroffand unplugthe power cordfromtheoutletbeforerepositioningtheproduct.

Alsochecktheantennacableortheexternalconnectors iftheyare fullyunplugged.Damagetothecordmay

causefireor electricshock.

Keeptheantennafar awayfromanyhigh-voltagecables andinstallit firmly.Contactwiththehigh-voltagecableor theantennafallingovermaycausefire or electricshock.

WhenconnectingtheRFantenna,checkfor a DTV receivingsystemandinstalla separateDTVreception antennaforareaswithno DTVsignal.

Checkthe basicsof the screentest.
