Makesureall protectivedevicesare properlyinstalled

includingnon-metallichandlesandcompartmentcovers

wheninstallingor re-installingthe chassisor chassis

Warningfor EngineeringChanges:

Nevermakeany changesor additionsto the circuit

designorthe internalpartfor this product.

Ex: Do notaddany audioor videoaccessory

connectors.Thismightcausephysicaldamage.

Furthermore,anychangesor additionsto theoriginal

design/engineeringwill invalidatethe warranty.

Warning— HotChassis:

SomeTV chassisaredirectlyconnectedto oneendof

theAC powercordfor electricalreasons.

Withoutinsulated transformers,the productcanonly be

repairedsafelywhen thechassisis connectedto the

earthedend of theAC powersource.

TomakesuretheAC powercord is properlyconnected,

followthe instructionsbelow.Usethe voltmeterto

measurethe voltagebetweenthe chassisandthe

earthedground.If the measurementis over 1.0V,unplug

theAC powercord andchangethe polaritybeforere-

insertingit. Measurethe voltagebetweenthe chassis

andthe groundagain.

SomeTV chassisareshippedwithan additional

secondarygroundingsystem.Thesecondarysystemis

adjacentto theAC powerline.Thesetwogrounding

systemsareseparatedin the circuitusingan

unbreakable/unchangeableinsulationmaterial.

Whenany parts,materialor wiringappearoverheatedor

damaged,replacethemwithnew regularones

immediately.Whenany damageor overheatingis

detected,correctthisimmediatelyand makea regular

checkof possibleerrors.

,A highvoltageis maintainedwithinthe specifiedlimits

,Checkfor the originalshapeof the lead,especiallythat

of the antennawiring,anysharpedges,the AC power

andthe highvoltagepower.Carefullycheck if the wiring

is too tight, incorrectlyplacedor loose.Neverchangethe

spacebetweenthe partand the printedcircuitboard.

ChecktheAC powercordfor possibledamages.Keep

the partor the leadawayfromany heat-emitting

materials.

1-2Servicing Precautions

Warning1: Firstcarefullyreadthe «Safety Instruction»inthisservicemanual,

Whenthereis a conflictbetweenthe serviceandthe safetyinstructions,followthe safetyinstructionat all times,

Warning2:Any electrolyticcapacitorwiththe wrongpolaritywill explode,

,

,

,

,

The serviceinstructionsare printedon the cabinet,and

shouldbefollowedby any servicepersonnel,

Makesureto unplugtheAC powercordfromthe power

sourcebeforestartingany repairs,

(a) Removeorre-installpartsor assemblies,

(b) Disconnectthe electricplugor connector,if any,

(c) Connectthe test partin parallelwiththe electrolytic

capacitor.

Somepartsareplacedat a higherpositionthan the

printedboard.Insulatedtubesortapesare usedfor this

purpose.The internalwiringis clampedusing bucklesto

avoidcontactwithheat emittingparts,Thesepartsare

installedbackto theiroriginalposition.

Afterthe repair,makesureto checkif the screws,parts

or cablesare properlyinstalled.Makesure nodamageis

causedto the repairedpartand itssurroundings,

Checkfor insulationbetweenthe bladeof the AC plug

andthatof anyconductivematerials(i,e,the metal

panel,inputterminal,earphonejack, etc),

6, InsulationCheckProcess:Unplugthe powercord from

theAC sourceand turnthe switchon. Connectthe insu-

latingresistancemeter(500v)to the AC plugblade,

The insulatingresistancebetweenthe bladeof theAC

plugandthatof the conductivematerialshouldbemore

than 1 M_,

7, Any B+interlockshouldnot be damaged,

If the metalheatsinkis not properlyinstalled,no

connectionto theAC powershouldbemade,

,Makesurethe groundingleadof the testeris connected

to the chassisgroundbeforeconnectingto the positive

lead.The groundleadof the testershouldberemoved

last.

9, Bewareof risksof any currentleakagecominginto

contactwiththe high-capacitycapacitor,

10, The sharpedgesof the metalmaterialmaycause

physicaldamage,so ensurewearingprotectivegloves

duringthe repair.

1-3Static Electricity Precautions

,

,

,

Somesemi-conductive(«solidstate»)devicesare

vulnerableto staticelectricity.Thesedevicesare known

as ESD.ESDincludesthe integratedcircuitandthefield

effecttransistor.To avoidanymaterialsdamagefrom

electrostaticshock,followthe instructionsdescribed

below.

Removeany staticelectricityfromyour bodyby

connectingthe earthgroundbeforehandlingany

semi-conductivepartsor ass’ys.Alternatively,weara

dischargeablewrist-belt.

(Makesure to removeany staticelectricitybefore

connectingthe powersource- this is a safetyinstruction

for avoidingelectricshock)

Removethe ESDass’yand placeit on a conductive

surfacesuchas aluminumfoil to preventaccumulating

staticelectricity.

,

,

g,

Useonly anti-staticsolderremovaldevices.

Mostsolderremovaldevicesdo not supportan

anti-staticfeature.A solderremovaldevicewithoutan

anti-staticfeaturecan storeenoughstaticelectricityto

causedamageto the ESD.

Do not removethe ESDfromthe protectivebox untilthe

replacementis ready.MostESD replacementsare

coveredwith lead,whichwill causea shortto the entire

unit dueto the conductivefoam,aluminumfoil or other

conductivematerials.

Removethe protectivematerialfrom the ESD

chassisor circuitass’y.

Takeextremecautionin handlingany uncoveredESD

replacements.Actionssuchas brushingclothesor lifting

Donot use any Freon-basedchemicals.

1-4 Installation Precautions

,

,

,

Forsafetyreasons,morethan twopeopleare required

for carryingthe product.

Keepthe powercord awayfromany heat emitting

devices,as a meltedcoveringmaycausefire orelectric

shock.

Wheninstallingthe product,makesureto keepit away

fromthewall (morethan 10cm/4inches)for ventilation

purposes.

Poorventilationmaycausean increasein the internal

temperatureof the product,resultingin ashortened

componentlife anddegradedperformance.

,

,

Makesureto turn the poweroffand unplugthe power

cordfromthe outletbeforerepositioningthe product.

Alsocheckthe antennacable orthe externalconnectors

if theyare fullyunplugged.Damageto the cordmay

causefire or electricshock.

Keeptheantennafar awayfromany high-voltagecables

andinstallit firmly.Contactwiththe high-voltagecableor

the antennafallingover maycausefire or electricshock.

Whenconnectingthe RFantenna,checkfor a DTV

receivingsystemandinstalla separateDTVreception

antennafor areaswithno DTVsignal.

Checkthe basicsof the screentest.

3, Noise:

Internalnoisemaybe causedby aforeignsubstanceon the fan or drivingdevice.

For a DLPTV,the lampfan,DMDboardfan and colorwheelarevulnerableto noise.Sometimesthe connectorwire aroundthe

lampor DMDfan makescontactwith thefan, whilethe colorwheelis protectedinsidethe moduleandcannotmakecontactwith

any nearbywires. Howeverthe colorwheelsensoror the drive motormaycausenoiseby makingcontactwiththe colorwheel.

As the colorwheelusesan air bearingsystem,it hasa veryslightpossibilityof creatinginternalnoise.

Whenirregularnoiseoccursfor noparticularreason,checkthe insideof the TV for anyforeignsubstances.

The DLPprojectionTV maycausenoiseas the physicalscreenis emptyinside,causinga resonanceto a particularfrequency.

Thusa lowvibrationis nota malfunction.

Any ‘creaking’noiseis mostlyfromthe structureof the deviceitself.Ashort, harshnoisemayoccurfroma distortionor

malformationdueto thermalexpansionbetweenthe metaljoints,screwsandloadedparts,respectively.Any intermittent‘creaking’

noisecan be removedby looseningthescrews.
