IMPORTANT SERVICE SAFETY PRECAUTION
Service workshould be performed only by qualified service technicians who are thoroughly
familiar withall safety checks and the servicing guidelines which follow:
4A 125V
SER VICING 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 withan 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
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 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.High voltage should alwaysbe kept at the rated value
-no higher. Operationat 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.Whenthe high voltage regulator is operating properly
there is no possibility of an X-radiation problem.
Every time acolorchassis is serviced,the brightness
should be tested while monitoring the high voltage
witha 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
troubles hooting
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.
WARNING
1. For continued safety, no modification of any circuit
should be attempted.
2. Disconnect AC powerbefore servicing.
3.Semiconductor heat sinks are potential
shock
hazards when the chassis is operating.
4. The chassis in this receiver has two
ground
systems
whichare separatedby insulating material. The
non-
isolated (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.
Toprevent 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
ONLYWITH SAME TYPE 4A-
125V FUSE.

SAFETY NOTICE
Many electrical and mechanical parts in television
recevers have special safety-related characteristics.
These characteristics are often not evident from visual
inspection, nor can protection afforded by them be
necessarily increased byusing replacement components
rated for higher voltage, wattageand etc.
Replacement parts which have these special safety
characteristics are identified in this manual; electrical
components havingsuch features are identified by " "
and shaded areas in the Replacement Parts Lists and
Schematic Diagrams.
IMPORTANT SER VICE SAFETY PRECAUTION
(Continued)
1. Inspect all lead dress to make certain that leads are
not pinchedor that hardwareis not lodgedbetween
the chassis and other metal parts in the receiver.
2. Inspect all protectivedevices such as non-metallic
control knobs, insulating materials, cabinet backs,
adjustment and compartment covers or shields,
isolation resistor-capacity networks, mechanical
insulatorsand etc.
3. To be sure that no shock hazard exists, check for
leakage currentin 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 conduitor 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.
For continued protection, replacement parts must be
identical to those used in the original circuit.The use of
substitute replacement parts which do not have the same
safety characteristics as the factory recommended
replacement parts shown in this service manual, may
create shock, fire, X-radiation or other hazards.
BEFORE RETURNING THE RECEIVER
(Fire Shock Hazard)
Before returning the receiver to the user, perform
the following safety checks.
Connectthe resistorconnection to all exposed metal
parts having a returnto the chassis (antenna, metal
cabinet, screw heads, knobs and control shafts,
escutcheon and etc.) and measure the AC voltage
drop across the resistor.
AII checks must be repeated with the AC line cord
plug connection reversed. (If necessary, a non-
polarized adapter plug must be used only for the
purposeof 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 mustbe taken before returning the
instrument to the customer.

CIRCUIT PROTECTION
The receiver is protected by a 4.0A fuse (F701),
mounted on PWB-A, wired into one side of the AC
line input.
X-RADIATION PROTECT OR 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 normalpicture and sound.
3. Receive a good local channel.
4. Connect a digital voltmeter to TP653 and make sure
that the voltmeter reads 21.4 ±1.5V.
5.Apply external 27.2V DC at TP653 by using an
external DC supply, TV must be shut of f.
6. To reset the protector , unplug the AC cord and make
a short circuit between TP651 and TP652. 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 VOLTAGE 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
adjustment "S03" and Bus data "01" (Y-mute on).
4.The voltage should be approximately 26.0kV (at zero
beam).
If a correct reading cannot be obtained, check
circuitry for malfunctioning components. After the
voltage test, make Y-mute of f to the normal mode.
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.
