IMPORTANT SERVICE SAFETY PRECAUTION
ËServicework should beperformed only byqualifiedservice technicians whoare thoroughly
familiar with all safety checks and the servicing guidelines which follow:
4A 125V
SERVICING OF HIGH VOLTAGE SYSTEM
AND PICTURE TUBE
When servicing the high voltage system,
remove the static charge by connecting a
10k ohm resistor in series with an insulated
wire (such as a test probe) between the pic-
ture tube ground and the anode lead. (AC
line cord should be disconnected from AC
outlet.)
1. Picture tube in this receiver employs integral
implosion protection.
2. Replace with tube of the same type number for
continued safety.
3. Do not lift picture tube by the neck.
4. Handle the picture tube only when wearing
shatterproof goggles and after discharging the high
voltage anode completely.
X-RADIATION AND HIGH VOLTAGE LIMITS
1. Be sure all service personnel are aware of the
proceduresand instructionscovering X-radiation.The
only potential source of X-ray in current solid state
TVreceiversis thepicturetube. However, thepicture
tube does not emit measurable X-Ray radiation, if
the high voltage is as specified in the "High Voltage
Check" instructions.
It is only when high voltage is excessive that X-
radiation is capable of penetrating the shell of the
picture tube including the lead in the glass material.
The important precaution is to keep the high voltage
below the maximum level specified.
2. It is essential that servicemen have available at all
times an accurate high voltage meter.
The calibration of this meter should be checked
periodically.
3. Highvoltageshould alwaysbekept atthe ratedvalue
−no higher. Operation at higher voltages may cause
a failure of the picture tube or high voltage circuitry
and;also, under certain conditions, may produce
radiation in exceeding of desirable levels.
4. Whenthehigh voltageregulatoris operatingproperly
thereisnopossibilityofanX-radiationproblem.Every
timeacolorchassisisserviced,thebrightnessshould
be tested while monitoring the high voltage with a
meter to be certain that the high voltage does not
exceed the specified value and that it is regulating
correctly.
5. Do not use a picture tube other than that specified or
make unrecommended circuit modifications to the
high voltage circuitry.
6. Whentroubleshootingandtaking testmeasurements
onareceiverwithexcessivehighvoltage,avoidbeing
unnecessarily close to the receiver.
Do not operate the receiver longer than is necessary
to locate the cause of excessive voltage.
WARNING
1. For continued safety, no modification of any circuit
should be attempted.
2. Disconnect AC power before servicing.
3. Semiconductor heat sinks are potential shock
hazards when the chassis is operating.
4. The chassis in this receiver has two ground systems
whichareseparated byinsulatingmaterial. Thenon-
isolated (hot) ground system is for the B+ voltage
regulatorcircuitand thehorizontaloutput circuit.The
isolatedgroundsystem isforthe lowB+DC voltages
and the secondary circuit of the high voltage
transformer.
To prevent electrical shock use an isolation
transformer between the line cord and power
receptacle, when servicing this chassis.
CAUTION: FOR CONTINUED
PROTECTION AGAINST A
RISK OF FIRE, REPLACE
ONLY WITH SAME TYPE 4A-
125V FUSE.

SAFETY NOTICE
Many electrical and mechanical parts in television
receivers have special safety-related characteristics.
These characteristics are often not evident from visual
inspection, nor can protection afforded by them be
necessarilyincreased byusing replacementcomponents
rated for higher voltage, wattage, etc.
Replacement parts which have these special safety
characteristics are identified in this manual; electrical
components having such features are identified by "å"
and shaded areas in the Replacement Parts Lists and
Schematic Diagrams.
IMPORTANT SERVICE SAFETY PRECAUTION
(Continued)
1. Inspect all lead dress to make certain that leads are
not pinched or that hardware is not lodged between
the chassis and other metal parts in the receiver.
2. Inspect all protective devices such as non-metallic
control knobs, insulating materials, cabinet backs,
adjustment and compartment covers or shields,
isolation resistor-capacity networks, mechanical
insulators and etc.
3. To be sure that no shock hazard exists, check for
leakage current in the following manner.
•Plug the AC cord directly into a 120 volt AC outlet,
(Do not use an isolation transformer for this test).
•Using two clip leads, connect a 1.5k ohm, 10 watt
resistorparalleledbya0.15µFcapacitorinserieswith
all exposed metal cabinet parts and a known earth

PRECAUTIONS A PRENDRE LORS DE LA REPARATION
Ne peut effectuer la réparation qu' un technicien spécialisé qui s'est parfaitement
accoutumé à toute vérification de sécurité et aux conseils suivants.
AVERTISSEMENT
1. N'entreprendre aucune modification de tout circuit.
C'est dangereux.
2. Débrancher le récepteur avant toute réparation.
3. Les déversoirs thermiques à semi-conducteurs
peuvent présenter un danger de choc électrique
lorsque le réceqteur est en marche.
4. Le châssis de ce récepteur possède deux systèmes
de masse qui sont séparées par du matériel
d'isolation. Le système de masse non-isolée (sous
tension) est pour le circuit du régulateur de tension
B+ et le circuit de sortie horizontale. Le système de
masse isolée est pour les tensions DC B+ basses et
lecircuitsecondairedutransformateur hautetension.
Pour éviter tout risque d'électrocution lors de
l'entretien de ce châssis, utiliser un transformateur
d'isolation entre le cordon de ligne et la prise de
courant.
4A 125V
PRECAUTION: POUR LA
PROTECTION CONTINUE
CONTRE LES RISQUES
D'INCENDIE, REMPLACER LE
FUSIBLE PAR UN FUSIBLE DE
MEME TYPE 4A-125V.
REPARATION DU SYSTEMEAHAUTE TEN-
SION ET DU TUBE-IMAGE
Lors de la réparation de ce systéme,
supprimer la charge statique en branchant
une résistance de 10 kΩen série avec un fil
isolé (comme une sonde d'essai) entre la
mise à la terre du tube-image et le fil
d'anodel.(Le cordend'alimentation doit être
retiré de la prise murale.)
1. Le tube image dans ce récepteur emploie une
protection intégrée contre l'implosion.
2. Par mesure de sécurité, changer le tube-image pour
un tube du même numéro de type.
3. Ne pas lever le tube-image par son col.
4. Nemanipulerletube-imagequ'en porantdes lunettes
incassables et qu'après avoir déchargé totalement
la haute tension.
LIMITES DES RADIATIONS X ET DE LA
HAUTE TENSION
1. Tout le personnel réparateur doit être instruit des
instructions et procédés relatifs aux radiations X.
Le tube-image, seule source de rayons X dons les
téleviseurs transistorisés, n'émet pourtant pas de
rayonsmesurablessi lahautetension est maintenue
à un niveau préconisé dans la section "Vérification
de la haute tension".
C'estseulementquandlahautetensionestexcessive
que les rayons X peuvent entrer dans l'enveloppe du
tube-image y compris le conducteur de verre. Il est
important de maintenir la haute tension en-dessous
du niveau spécifié.
2. Il est essentiel que le réparateur ait sous la main un
voltmètreà haute tension qui doit être périodiquement
étalonné.
3. La haute tension doit toujours être maintenue à la
valeur de régime -et pas plus haute. L'opération à
des tensions plus élevées peut entraîner une panne
du tube-image ou du circuit à haute tension et, dans
certaines conditions, peut entraîner une radiation
dépassant les niveaux préscrits.
4. Quand le régulateur à haute tension fonctionne
correctement, il n'y a aucun problème de radiation
X. Chaque fois qu'un châssis couleurs est réparé, la
luminosité doit être examinée bout en contrôlant la
haute tension à l'aide d'un voltmètre pour s'assurer
que la haute tension ne dépasse pas la valeur
spécifiée et qu'elle soit correctement réglée.
5. Nepas utiliser un tube-imageautre que celuispécifié
et ne pas effectuer de modifications déconseillées
du circuit à haute tension.
6. Lors de la recherche des pannes et des mesures
d'essai sur un récepteur qui présente une haute
tension excessive, éviter de s'approcher inutilement
du récepteur.
Ne pas faire fonctionner le récepteur plus longtemps
que nécessaire pour localiser la cause de la tension
excessive.
