PRECAUTIONSDURINGSERVICING
1. Inaddition tosafety,otherpartsand assembliesare
specified forconformancewithsuchregulationsas
thoseapplying tospuriousradiation.Thesemust
alsobe replaced onlywithspecified replacements.
Examples:RFconverters,tunerunits,antenna
selection switches,RFcables,noise-blocking
capacitors,noise-blocking filters,etc.
2.Usespecified internalWiring.Noteespecially:
1)Wirescovered withPVCtubing
2)Doubleinsulated wires
3)High voltage leads
3.Usespecified insulating materialsforhazardous
liveparts.Noteespecially:
1)Insulating Tape
2)PVCtubing
3)Spacers(insulating barriers)
4)Insulating sheetsfortransistors
5)Plasticscrewsforfixing microswitches
4.When replacing ACprimaryside components
(transformers,powercords,noiseblocking
capacitors,etc.),wrap endsofwiressecurelyabout
the terminalsbeforesoldering.
5.Makesurethatwiresdo notcontactheatgenerating
parts(heatsinks,oxide metalfilmresistors,fusible
resistors,etc.)
6.Check ifreplaced wiresdo notcontactsharplyedged
orpointed parts.
7.Makesurethatforeign objects(screws,solder
droplets,etc.)do notremaininside the set.

WARNING:
Beforeservicing thisTVreceiver,read the X-RAY
RADIATIONPRECAUTION,SAFETYINSTRUCTION
and PRODUCTSAFETYNOTICE.
X-RAYRADIATIONPRECAUTION
1.Excessivelyhigh can producepotentiallyhazardous
X-RAY RADIATION.Toavoidsuchhazards,the high
voltage mustnotexceed the specified limit. The
normalvalue ofthe high voltage ofthisTVreceiver
is27 KV atzerobean current(minimumbrightness).
The high voltage mustnotexceed 30 KV underany
circumstances.Eachtimewhen areceiverrequires
servicing,the high voltage shouldbe checked.The
reading ofthe high voltage isrecommended tobe
recorded asapartofthe servicerecord,It is
importanttousean accurateand reliablehigh
voltage meter.
2.The onlysourceofX-RAY RADIATIONinthisTV
receiveristhe picturetube.Forcontinued X-RAY
RADIATIONprotection,the replacementtube mustbe
exactlythe sametype asspecified inthe partslist.
3.SomepartsinthisTVreceiverhavespecialsafety
related characteristics forX-RADIATIONprotection.
Forcontinued safety,the partsreplacementshould
be undertaken onlyafterreferring the PRODUCT
SAFETYNOTICE.
SAFETYINSTRUCTION
The serviceshouldnotbe attempted byanyone
unfamiliarwiththe necessaryinstructionson thisTV
receiver.The following arethe necessaryinstructions
tobe observed beforeservicing.
1.Anisolation transformershouldbe connected inthe
powerline between the receiverand the ACline
when aserviceisperformed on the primaryofthe
convertertransformerofthe set.
2.Complywithall caution and safetyrelated provided
on the back ofthe cabinet, inside the cabinet, on the
chassisorpicturetube.
3.Toavoidashock hazard,always discharge the
picturetube'sanode tothe chassisground before
removing the anode cap.
The lightning flashwitharrowhead symbol,

Thesecharacteristics areofferpassed unnoticed by
visualspection and the protection afforded bythem
cannotnecessarilybe obtained byusing replacement

4.Completelydischarge the high potentialvoltage ofthe
picturetube beforehandling.The picturetube isa
vacuumand ifbroken,the glass will explode.
5.When replacing aMAINPCBinthe cabinet, always
be certainthatall protectiveareinstalled properly
suchascontrolknobs,adjustmentcoversorshields,
barriers,isolation resistornetworks etc.
6.When servicing isrequired,observethe originallead
dressing.Extraprecaution shouldbe given toassure
correctlead dressing inthe high voltage area.
7.Keep wiresawayfromhigh voltage orhigh tempera
turecomponents.
8.Beforereturning the settothe customer,always
perform an ACleakage currentcheck on the exposed
metallicpartsofthe cabinet, suchasantennas,
terminals,screwheads,metaloverlay,controlshafts,
etc., tobe surethe setissafetooperatewithout
dangerofelectricalshock.Plug the ACline cord
directlytothe ACoutlet(do notusealine isolation
transformerduring thischeck).Usean ACvoltmeter
having 5Kohmsvoltsensitivityormoreinthe
following manner.
Connecta1.5Kohm10 watt resistorparalleled bya
0.15µFACtype capacitor,between agood earth
ground (waterpipe,conductoretc.,)and the exposed
metallicparts,one atatime.
Measurethe ACvoltage across the combination of
the 1.5Kohmresistorand 0.15 uFcapacitor.Reverse
the ACplug atthe ACoutletand repeatthe AC
voltage measurementsforeachexposed metallic
part.
The measured voltage mustnotexceed 0.3VRMS.
Thiscorrespondsto0.5mAAC.Anyvalue exceeding
thislimitconstitutesapotentialshock hazardand
mustbe corrected immediately.
The resistancemeasurementshouldbe done
between accessibleexposed metalpartsand power
cordplug prongswiththe powerswitch"ON".The
resistanceshouldbe morethan 6Mohms.
