These models(ColorEVFmodels) havetwomarks (Model No.
Identification Mark) suchas Aand AA forPV-D301, Dand DAforPV-
L551, etc., inthisservice manual.
Whenservicing these models, please note thepropermarkand
proceedwithservicing as shownbelow.
Howtodistinguishmarks Afrom AA, Dfrom DA, etc.:
To distinguish, "A"isprintedon theSerial No. on theRating Label
locatedon thebottomsideofthecamcorderforearlyproducts, and
isshownwithModel No. Identification Mark:AA, DA, EA, FA, GA,

GENERALGUIDELINES
1. IMPORTANTSAFETYNOTICE

Therearespecial components usedinthisequipmentwhichare
importantforsafety. These parts aremarkedby inthe
SchematicDiagrams, CircuitBoardLayout, ExplodedViewsand
ReplacementParts List. Itisessential that these critical parts
shouldbereplacedwithmanufacturer'sspecifiedparts toprevent
X-RADIATION, shock, fire, orotherhazards. Donotmodifythe
original design withoutpermission ofmanufacturer.
2. AnIsolation Transformershouldalwaysbeusedduring the
servicing ofACAdaptorwhose chassisisnotisolatedfromtheAC
powerline. Use atransformerofadequate powerrating as this
protects thetechnicianfromaccidents resulting inpersonal injury
fromelectrical shocks. Itwill alsoprotect ACAdaptorfrombeing
damagedbyaccidental shorting that mayoccurduring servicing.
3. Whenservicing, observetheoriginal leaddress. Ifashortcircuit
isfound, replace all parts whichhavebeenoverheatedor
damagedbytheshortcircuit.
4. Afterservicing, see toitthat all theprotectivedevices suchas
insulation barriers, insulation papersshieldsareproperlyinstalled.
5. Afterservicing, make thefollowing leakagecurrentchecks to
preventthecustomerfrombeing exposedtoshock hazards.
LEAKAGE CURRENTCOLDCHECK
1. Unplug theACcordand connect ajumperbetweenthetwoprongs
on theplug.
2. Measuretheresistance value, withanohmmeter, betweenthe
jumperedACplug and eachexposedmetalliccabinet parton the
equipmentsuchas screwheads, connectors, control shafts, etc.
Whentheexposedmetallicparthas areturnpathtothechassis,
thereading shouldbebetween1M and 5.2M . Whenthe
exposedmetal does nothaveareturnpathtothechassis, the
reading must beinfinity.
LEAKAGE CURRENTHOTCHECK
(See Figure1.)
1. Plug theACcorddirectlyintotheACoutlet. Donotuse an
isolation transformerforthischeck.
2. Connect a1.5k , 10 Wresistor, inparallel witha0.15 F
4

capacitor, betweeneachexposedmetallicparton theset and a
good earthground, as showninFigure1.
3. Use anACvoltmeter, with1M /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. A
leakagecurrenttester(Simpson Model 229 orequivalent) maybe
usedtomake thehotchecks, leakagecurrentmust notexceed1/2
mA. Incase ameasurementisoutsideofthe/limits specified,
thereisapossibilityofashock hazard, and theequipmentshould
berepairedand recheckedbeforeitisreturnedtothecustomer.

3. PREVENTIONOFELECTRO STATICDISCHARGE
(ESD) TO ELECTROSTATICALLYSENSITIVE (ES)
DEVICES
Somesemiconductor (solidstate)devices canbedamagedeasilybystaticelectricity. Such
componentscommonlyarecalledElectrostaticallySensitive (ES)Devices. Examples oftypical
ES devices areintegratedcircuitsand somefield-effecttransistorsand semiconductor "chip"
components. Thefollowing techniques shouldbeusedtohelpreduce theincidence of
componentdamagecausedbyelectro staticdischarge(ESD).
1. Immediatelybeforehandling anysemiconductorcomponentor
semiconductor-equippedassembly, drainoff anyESDon your
bodybytouching aknownearthground. Alternatively, obtainand
wearacommerciallyavailabledischarging ESDwrist strap, which
shouldberemovedforpotential shock reasonspriortoapplying
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 orcomparable
conductivematerial).
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).
4. X-RADIATION
(For model withMonochromeEVF)
WARNING:
1. Thepotential source ofX-Radiation inEVFsets istheHigh Voltage
section and thepicturetube.
2. Whenusing apicturetubetest jigforservice, ensurethat jigis
6

capableofhandling 10 kVwithoutcausing X-Radiation.
NOTE :
Itisimportanttouse anaccurate periodicallycalibratedhigh
voltagemeter.
3. MeasuretheHigh Voltage. Themeter(electrostatictype) reading
shouldindicate 2.2kV±0.1kV. Ifthemeterindication isoutof
tolerance, immediate service and correction isrequiredtoprevent
thepossibilityofprematurecomponentfailure. To preventanX-
Radiation possibility, itisessential touse thespecifiedpicture
tube.
