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(ACLeakageTest)

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.

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.
