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.

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
