1. SAFETYPRECAUTIONS

GENERALGUIDELINES

1. IMPORTANTSAFETYNOTICE

Therearespecial components usedinthisequipmentwhichare

importantforsafety. These parts aremarkedbyinthe

SchematicDiagrams, CircuitBoardLayout, ExplodedViewsand

ReplacementParts List. Itisessential that these criticalparts

shouldbereplacedwithmanufacturer'sspecifiedparts toprevent

X-RADIATION, shock, fire, orotherhazards. Donotmodifythe

original design withoutpermission ofmanufacturer.

2. AnIsolation Transformershouldalwaysbeusedduring the

servicing ofCombination VCR whose chassisisnotisolatedfrom

theACpowerline. Use atransformerofadequate powerrating as

thisprotects thetechnicianfromaccidents resultinginpersonal

injuryfromelectrical shocks. Itwill alsoprotect Combination VCR

frombeing damagedbyaccidental shorting that mayoccurduring

servicing.

3. Whenservicing, observetheoriginal leaddress, especiallythe

leaddress inthehigh voltagecircuits. Ifashortcircuitisfound,

replace all parts whichhavebeenoverheatedordamagedbythe

shortcircuit.

4. Afterservicing, see toitthat all theprotectivedevices suchas

insulation barriers, insulation papers, shield, and isolation R-C

combinationsareproperlyinstalled.

5. Beforeturning thereceiveron, measuretheresistance betweenB+

lineand chassisground. Connect (-) sideofanohmmetertotheB

+lines, and (+)sidetochassisground. Eachlineshouldhave

moreresistance thanspecified,as follows:

(Formodel with13 inchCRT)

6. WhentheTVset isnotusedforalong period oftime, unplug the

powercordfromtheACoutlet.

7. Potentials, as high as 25.0kV(Formodel with13 inchCRT)or30.0

kV(Formodel with20 inchCRT)or32.0kV(Formodel with25

inchCRT)arepresentwhenthisTVset isinoperation. Operation

oftheTVset withouttherearcoverinvolvesthedangerofashock

hazardfromtheTVset powersupply. Servicing shouldnotbe

attemptedbyanyonewho isnotthoroughlyfamiliarwiththe

precautionsnecessarywhenworking on high voltageequipment.

AlwaysdischargetheanodeofthepicturetubetotheCRTground

ofreceiverbeforehandling thetube.

8. Afterservicing make thefollowing leakagecurrentchecks to

preventthecustomerfrombeing exposedtoshock hazards.

LEAKAGE CURRENTCOLDCHECK

1. Unplug theACcordand connect ajumperbetweenthetwoprongs

on theplug.

2. Forphysicallyoperatedpowerswitches, turnpoweron. Otherwise

skipstep2.

3. Measuretheresistance value, withanohmmeter, betweenthe

jumperedACplug and eachexposedmetalliccabinet parton the

receiver, suchas screwheads, connectors, etc. Whentheexposed

metallicparthas areturnpathtothechassis, thereadingshould

bebetween1M and 12 M . Whentheexposedmetal does not

haveareturnpathtothechassis, thereading must beinfinity.

LEAKAGE CURRENTHOTCHECK

1. Plug theACcorddirectlyintotheACoutlet.

Donotuse aisolation transformerforthischeck.

2. Connect a1.5k , 10 Wresistor, inparallel witha0.15 F

capacitor, betweeneachexposedmetallicparton theset and a

good earthground , as showninFigure1.

3. Use anACvoltmeter, with1k /Vormoresensitivity, tomeasure

thepotential across theresistor.

4. Check eachexposedmetallicpart, and measurethevoltageat

eachpoint.

5. Reverse theACplug intheACoutlet and repeat eachoftheabove

measurements.

6. Thepotential at anypointshouldnotexceed0.75 VRMS.

Aleakagecurrenttester(Simpson Model 229 equivalent) maybe

usedtomake thehotchecks. Leakagecurrentmust notexceed1/2

mA. Incase ameasurementisoutsideofthelimits specified, there

isapossibilityofshock hazard, and thereceivershouldbe

repairedand recheckedbeforeitisreturnedtothecustomer.

2. X-RADIATION

WARNING:

1. Thepotential source ofX-Radiation inTVsets istheHigh Voltage

section and thepicturetube.

2. Whenusing apicturetubetest fixtureforservice, ensurethat the

fixtureiscapableofhandling 25.0kV(Formodel with13 inchCRT)

or30.0kV(Formodel with20 inchCRT)or32.0kV(Formodel with

25 inchCRT)withoutcausing X-Radiation.

NOTE :

Itisimportanttouse anaccurate periodicallycalibratedhigh

voltagemeter.

1. Reduce thebrightness tominimum.

2. Set theSERVICEswitchtoSERVICE.

3. MeasuretheHigh Voltage. Themeterreading shouldindicate 23.5

kV±1.5kV(Formodel with13 inchCRT)or28.5kV±1.5kV(For

model with20 inchCRT)or30.0kV±2.0kV(Formodel with25 inch

CRT).

Ifthemeterindication isoutoftolerance, immediate service and

correction isrequiredtopreventthepossibilityofpremature

componentfailure.

4. To preventanX-Radiation possibly, itisessential touse the

specifiedpicturetube.

HORIZONTALOSCILLATORDISABLE CIRCUITTEST

SERVICE WARNING:

Thetestmustbemadeas afinal check beforesetisreturnedtothecustomer.

1. Withtherearcoverremoved, supplyabouta90 VACpower

source totheset, turnon theset.

2. Set thecustomercontrolstonormal operating positions.

3. Shortbothsides ofR804 on theMaincircuitboardwithajumper

wire. Confirm that thepicturegoes outofhorizontal sync.

4. Ifthisdoes notoccur, thehorizontal oscillatordisablecircuitis

notoperating. Follow theRepairProcedures ofhorizontal

oscillatordisablecircuitbeforetheset isreturnedtocustomer.

REPAIRPROCEDURES OFHORIZONTALOSCILLATORDISABLE CIRCUIT

1. Connect aDC voltmeterbetweencapacitorC513 (+)on theMain

circuitboardand chassisground.

2. Ifapproximately+21.0V(Formodel with13 inchCRT)or+21.9V

(Formodel with20 inchCRT)or+23.5V(Formodel with25 inch

CRT)isnotpresentat that pointwhen120 VACisapplied, find the

cause. Check R503,R5505, C5507, C513 and D503.

3. Carefullycheck abovespecifiedparts and relatedcircuits and

parts. Whenthecircuitisrepaired, trythehorizontal oscillator

disablecircuittest again.

CIRCUITEXPLANATION

HORIZONTALOSCILLATORDISABLE CIRCUIT

Thepositive DC voltage, suppliedfrom theD503 cathodefor monitoring high voltage, isapplied

totheIC5301 Pin11 through R503 and R5504. Undernormal conditions, thevoltageatIC5301 Pin

11 isless thanapprox3V. Ifthehigh voltageatFlybackTrPin5exceedsthespecifiedvoltage,

thepositive DC voltagewhichissuppliedfrom theD503 cathodealsoincreases. Theincreased

voltageisappliedtoIC5301 Pin11 through R503 and R5504. Duetotheincreasedvoltageat

IC5301 Pin11, thehorizontaloscillator frequency increases, thepicturegoes outofhorizontal

sync, thebeam currentdecreases and thepicturebecomes darkinordertokeepX-radiation

underspecification.

3. PREVENTIONOFELECTROSTATICDISCHARGE

(ESD) TO ELECTROSTATICALLYSENSITIVE (ES)

DEVICES

Somesemiconductor (solidstate)devices canbedamagedeasilybystaticelectricity. Such

componentscommonlyarecalledElectrostaticallySensitive (ES)Devices. Examples oftypical

ES devices areintegratedcircuitsand somefield-effecttransistorsaresemiconductor "chip"

components. Thefollowing techniques shouldbeusedtohelpreduce theincidence of

componentdamagecausedbyelectrostaticdischarge(ESD).

1. Immediatelybeforehandling anysemiconductorcomponentor

semiconductor-equippedassembly, drainoff anyESDon your

bodytouching aknownearthground. Alternatively, obtainand

wearacommerciallyavailabledischarging ESDwrist strap,

whichshouldberemovedforpotential shock reasonspriorto

applying powertotheunitundertest.

2. Afterremoving anelectrical assemblyequippedwithES devices,

place theassemblyon aconductivesurface suchas aluminum

foil, topreventelectrostaticchargebuildup orexposureofthe

assembly.

3. Use onlyagrounded-tipsoldering iron tosolderorunsolderES

devices.

4. Use onlyanantistaticsolderremoval device. Somesolderremoval

devices notclassifiedas "antistatic(ESDprotected)"cangenerate

electrical chargesufficienttodamageES devices.

5. Donotuse freon-propelledchemicals. These cangenerate

electrical charges sufficienttodamageES devices.

6. DonotremoveareplacementES device fromits protective

packageuntil immediatelybeforeyou arereadytoinstall it. (Most

replacementES devices arepackagedwithleadselectrically

shortedtogetherbyconductivefoam, aluminumfoil or

comparableconductivematerial).

7. Immediatelybeforeremoving theprotectivematerial fromthe

leadsofareplacementES device, touchtheprotectivematerial to

thechassisorcircuitassemblyintowhichthedevice will be

installed.

CAUTION:

Besureno powerisappliedtothechassisorcircuit, and observe

all othersafetyprecautions.

8. Minimizebodilymotionswhenhandling unpackagedreplacement

ES devices. (Otherwise harmless motion suchas thebrushing

togetherofyourclothes fabricorthelifting ofyourfootfroma

carpetedfloorcangenerate staticelectricity(ESD)sufficientto

damageanES device).

"NOTE toCATV system installer:

Thisreminderisprovidedtocall theCATV system installer's attention toArticle820-40 ofthe

NECthatprovides guidelines for propergrounding and, inparticular, specifies thatthecable

ground shall beconnectedtothegrounding systemofthebuilding, as close tothepointofcable
