1.Precaution

Toavoidpossibledamage,electricshocksorexposuretoradiation,followtheinstructionsbelowwithregardtosafety, installation,serviceandESD.

1.1.SafetyPrecautions

1)Makesureallprotectivedevicesareproperlyinstalledincludingnon-metallichandlesandcompartmentcoverswhen installingorre-installingthechassisorchassisassemblies.

2)Makesurethatnogapsexistbetweenthecabinetsforchildrentoinserttheirngersintopreventchildrenfrom receivingelectricshocks.GapsmentionedaboveincludeventilationholesofatoogreatmagnitudebetweenthePDP moduleandthecabinetmask,andtheimproperinstallationoftherearcabinet.

Errorsmayoccurwhentheresistanceisbelow1.0MΩorover5.2MΩ.Inthesecases,makesurethatthedeviceis repairedbeforesendingitbacktothecustomer.

3)CheckforElectricityLeakage(ACLeakageT est)

WARNING

Donotuseaninsulatedtransformerforcheckingtheleakage.Useonlythosecurrentleakagetestersormirroring systemsthatcomplywithANSIC101.1andtheUnderwriterLaboratory’sspecications(UL1410,59.7).

4)Ahighvoltageismaintainedwithinthespeciedlimitsusingsafetyparts,calibrationandtolerances.Whenvoltage exceedsthespeciedlimits,checkeachspecialpart.

5)W arningforEngineeringChanges:

Nevermakeanychangesoradditionstothecircuitdesignortheinternalpartforthisproduct.

Ex:Donotaddanyaudioorvideoaccessoryconnectors.Thismightcausephysicaldamage.

Furthermore,anychangesoradditionstotheoriginaldesign/engineeringwillinvalidatethewarranty.

6)W arning-HotChassis:

SomeTVchassisaredirectlyconnectedtooneendoftheACpowercordforelectricalreasons.Withoutinsulated transformers,theproductcanonlyberepairedsafelywhenthechassisisconnectedtotheearthedendoftheAC powersource.

TomakesuretheACpowercordisproperlyconnected,followtheinstructionsbelow.Usethevoltmetertomeasurethe voltagebetweenthechassisandtheearthedground.Ifthemeasurementisover1.0V ,unplugtheACpowercordand changethepolaritybeforereinsertingit.Measurethevoltagebetweenthechassisandthegroundagain.

7)SomeTVchassisareshippedwithanadditionalsecondarygroundingsystem.Thesecondarysystemisadjacentto theACpowerline.Thesetwogroundingsystemsareseparatedinthecircuitusinganunbreakable/unchangeable insulationmaterial.

8)Whenanyparts,materialorwiringappearoverheatedordamaged,replacethemwithnewregularonesimmediately. Whenanydamageoroverheatingisdetected,correctthisimmediatelyandmakearegularcheckofpossibleerrors.

9)Checkfortheoriginalshapeofthelead,especiallythatoftheantennawiring,anysharpedges,theACpowerandthe highvoltagepower.Carefullycheckifthewiringistootight,incorrectlyplacedorloose.Neverchangethespace betweenthepartandtheprintedcircuitboard.ChecktheACpowercordforpossibledamages.Keepthepartorthe leadawayfromanyheat-emittingmaterials.

1.2.ServicingPrecautions

WARNING

1)Firstcarefullyreadthe“SafetyInstruction”inthisservicemanual.

Whenthereisaconictbetweentheserviceandthesafetyinstructions,followthesafetyinstructionatalltimes.

2)Anyelectrolyticcapacitorwiththewrongpolaritywillexplode.

1)Theserviceinstructionsareprintedonthecabinet,andshouldbefollowedbyanyservicepersonnel.

2)MakesuretounplugtheACpowercordfromthepowersourcebeforestartinganyrepairs.

a)Removeorre-installpartsorassemblies.

b)Disconnecttheelectricplugorconnector,ifany.

c)Connectthetestpartinparallelwiththeelectrolyticcapacitor.

3)Somepartsareplacedatahigherpositionthantheprintedboard.Insulatedtubesortapesareusedforthispurpose. Theinternalwiringisclampedusingbucklestoavoidcontactwithheatemittingparts.Thesepartsareinstalledback totheiroriginalposition.

4)Aftertherepair,makesuretocheckifthescrews,partsorcablesareproperlyinstalled.Makesurenodamageiscaused totherepairedpartanditssurroundings.

1.Precaution

5)CheckforinsulationbetweenthebladeoftheACplugandthatofanyconductivematerials(i.e.themetalpanel, inputterminal,earphonejack,etc).

6)InsulationCheckProcess:

UnplugthepowercordfromtheACsourceandturntheswitchon.Connecttheinsulatingresistancemeter(500V)to theACplugblade.TheinsulatingresistancebetweenthebladeoftheACplugandthatoftheconductivematerial shouldbemorethan1MΩ.

7)AnyB+interlockshouldnotbedamaged.

Ifthemetalheatsinkisnotproperlyinstalled,noconnectiontotheACpowershouldbemade.

8)Makesurethegroundingleadofthetesterisconnectedtothechassisgroundbeforeconnectingtothepositivelead. Thegroundleadofthetestershouldberemovedlast.

9)Bewareofrisksofanycurrentleakagecomingintocontactwiththehigh-capacitycapacitor.

10)Thesharpedgesofthemetalmaterialmaycausephysicaldamage,soprotectyourselfbywearingglovesduringthe repair.

11)Duetothenatureofplasmadisplaypanels,partialafter-imagesmayappearifastillpictureisdisplayedonthescreen foralongperiodoftime.
