Service work should be performed only by qualified service technicians who are
thoroughly familiar with all safety checks and the servicing guidelines which follow:

IMPORTANT SERVICE SAFETY PRECAUTION

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
which are separated by insulating material. The non­isolated (hot) ground system is for the B+ voltage
regulator circuit and the horizontal output circuit. The
isolated ground system is for the low B+ 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

5A 125V

ONLY WITH SAME TYPE 5A­125V FUSE.

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 pic­ture 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
procedures and instructions covering X-radiation. The
only potential source of X-ray in current solid state
TV receivers is the picture tube. However, the picture
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 X­radiation 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. High voltage should always be kept at the rated value

−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. When the high voltage regulator is operating properly
there is no possibility of an X-radiation problem. Every
time a colour chassis is serviced, the brightness
should 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. When trouble shooting and taking test measurements
on a receiver with excessive high voltage, avoid being
unnecessarily close to the receiver.
Do not operate the receiver longer than is necessary
to locate the cause of excessive voltage.

36K-X2000 CK36S60

BEFORE RETURNING THE RECEIVER
(Fire & Shock Hazard)

Before returning the receiver to the user, perform
the following safety checks.

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, 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
resistor paralleled by a 0.15µF capacitor in series with
all exposed metal cabinet parts and a known earth
ground, such as electrical conduit or electrical ground
connected to earth ground.

• Use an AC voltmeter having with 5000 ohm per volt,
or higher, sensitivity to measure the AC voltage drop
across the resistor.

• Connect the resistor connection to all exposed metal
parts having a return to the chassis (antenna, metal
cabinet, screw heads, knobs and control shafts,
escutcheon, etc.) and measure the AC voltage drop
across the resistor.
AII checks must be repeated with the AC ine cord
plug connection reversed. (If necessary, a non­polarized adapter plug must be used only for the
purpose of completing these check.)
Any current measured must not exceed 0.5 milliamp.
Any measurements not within the limits outlined
above indicate of a potential shock hazard and
corrective action must be taken before returning the
instrument to the customer.

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
necessarily increased by using replacement components
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

Schematic Diagrams

PRECA UTIONS 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
le circuit secondaire du transformateur haute tension.
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.

PRECAUTION: POUR LA
PROTECTION CONTINUE
CONTRE LES RISQUES

5A 125V

D'INCENDIE, REMPLACER LE
FUSIBLE PAR UN FUSIBLE DE
MEME TYPE 5A-125V.

REPARATION DU SYSTEME A HAUTE TEN­SION ET DU TUBE-IMAGE

Lors de la réparation de ce systéme, supprimer
la charge statique en branchant une résistance
de 10 kΩ en série avec un fil isolé (comme une
sonde d'essai) entre la mise à la terre du tube­image et le fil d'anodel. (Le corden
d'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. Ne manipuler le tube-image qu'en porant des 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
rayons mesurables si la haute tension est maintenue
à un niveau préconisé dans la section "Vérification
de la haute tension".
C'est seulement quand la haute tension est excessive
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
voltmètre à 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. Ne pas utiliser un tube-image autre que celui spécifié
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.

PRECAUTIONS A PRENDRE LORS DE LA REPARATION

(Suite)

VERIFICATIONS CONTRE L'INCEN-DIE ET
LE CHOC ELECTRIQUE

Av ant de rendre le récepteur à l'utilisateur, effectuer les
vérifications suivantes.

1. Inspecter tous les faisceaux de câbles pour s'assurer
que les fils ne soient pas pincés ou qu'un outil ne soit
pas placé entre le châssis et les autres pièces
métalliques du récepteur.

2. Inspecter tous les dispositifs de protection comme
les boutons de commande non-métalliques, les
isolants, le dos du coffret, les couvercles ou blindages
de réglage et de compartiment, les réseaux de
résistance-capacité, les isolateurs mécaniques, etc.

3. S'assurer qu'il n'y ait pas de danger d'électrocution
en vérifiant la fuite de courant, de la facon suivante:

• Brancher le cordon d'alimentation directem-ent à une
prise de courant de 120V. (Ne pas utiliser de
transformateur d'isolation pour cet essai).

• A l'aide de deux fils à pinces, brancher une résistance
de 1,5 kΩ 10 watts en parallèle avec un condensateur
de 0,15µF en série avec toutes les pièces métalliques
exposées du coffret et une terre connue comme une
conduite électrique ou une prise de terre branchée à
la terre.

• Utiliser un voltmètre CA d'une sensibilité d'au moins
5000Ω/V pour mesurer la chute de tension en travers
de la résistance.

• Toucher avec la sonde d'essai les pièces métalliques
exposées qui présentent une voie de retour au
châssis (antenne, coffret métallique, tête des vis,
arbres de commande et des boutons, écusson, etc.)
et mesurer la chute de tension CA en-travers de la
résistance. Toutes les vérifications doivent être
refaites après avoir inversé la fiche du cordon
d'alimentation. (Si nécessaire, une prise d'adpatation
non polarisée peut être utilisée dans le but de terminer
ces vérifications.)
Tous les courants mesurés ne doivent pas dépasser
0,5 mA.
Dans le cas contraire, il y a une possibilité de choc
électrique qui doit être supprimée avant de rendre le
récepteur au client.

INSTALLATION AND SERVICE INSTRUCTIONS

Note: (1) When performing any adjustments to resistor controls and transformers use non-metallic

screwdrivers or TV alignment tools.

(2) Before performing adjustments, the TV set must be on at least 15 minutes.

CIRCUIT PROTECTION
The receiver is protected by a 5.0A fuse

(F701), mounted on PWB-C, wired into one
side of the AC line input.

X-RADIATION PROTECTOR CIRCUIT TEST

After service has been performed on the horizontal
deflection system, high voltage system, B+ system,
test the X-Radiation protection circuit to ascertain
proper operation as follows:

1) Apply 120V AC using a variac transformer for
accurate input voltage.

2) Allow for warm up and adjust all customer controls
for normal picture and sound.

3) Receive a good local channel.

4) Connect a digital voltmeter to TP653 and make sure
that the voltmeter reads 11.8 ±0.7V.

5) Apply external 14.5V DC at TP653 by using an
external DC supply, TV must be shut off.

6) To reset the protector, unplug the AC cord and plug
the AC cord power on. Now make sure that normal
picture appears on the screen.

7) If the operation of the horizontal oscillator does not
stop in step 5, the circuit must be repaired before the
set is returned to the customer.

HIGH VOLT A GE CHECK

High voltage is not adjustable but must be checked
to verify that the receiver is operating within safe
and efficient design limitations as specified checks
should be as follows:

1. Connect an accurate high voltage meter between
ground and anode of picture tube.

2. Operate receiver for at least 15 minutes at 120V AC
line voltage, with a strong air signal or a properly tuned
in test signal.

3. Enter the service mode and select the service No.
"S21" and Bus data "01" (Y-mute on).

4. The voltage should be approximately, 32.8kV(32K­X2000,CK32S60),33.4kV(36K-X2000,CK36S60).

(at zero beam)

If a correct reading cannot be obtained, check circuitry
for malfunctioning components. After the voltage test,
make Y-mute off to the normal mode.
