Design & specification are subject to change without notice.
Operating the receiver outside of its cabinet or with its
back removed involves a shock hazard. Work on
these models should only be performed by those who
are thoroughly familiar with precautions necessary
when working on high voltage equipment.
Exercise care when servicing this chassis with power
applied. Many B plus and high voltage RF terminals are
exposed which, if carelessly contacted, can cause
serious shock or result in damage to the chassis.
Maintain interconnecting ground lead connections
between chassis, escutcheon, picture tube dag and
tuner cluster when operating the chassis.
These receivers have a "polarized" AC line cord. The AC
plug is designed to fit into standard AC outlets in one
direction only. The wide blade connects to the "ground
side" and the narrow blade connects to the "hot side" of
the AC line. This assures that the TV receiver is properly
grounded to the house wiring. If an extension cord must
be used, make sure it is of the "polarized" type.
Since the chassis of this receiver is connected to one
side of the AC supply during operation, service should
not be attempted by anyone not familiar with the
precautions necessary when working on these types
When it is necessary to make measurements or tests with
AC power applied to the receiver chassis, an Isolation
Transformer must be used as a safety precaution and to
prevent possible damage to transistors. The Isolation
Transformer should be connected between the TV line
cord plug and the AC power outlet.
Certain HV failures can increase X-ray radiation.
Receivers should not be operated with HV levels
exceeding the specified rating for their chassis type. The
maximum operating HV specified for the chassis used in
these receivers is 32.5kV 1.0kV at zero beam current
with a line voltage of 120V AC. Higher voltage may also
increase the possibility of failure in the HV supply.
It is important to maintain specified values of all
components in the horizontal and high voltage circuits
and anywhere else in the receiver that could cause a rise
in high voltage, or operating supply voltages. No changes
should be made to the original design of the receiver.
Components shown in the shaded areas on the
schematic diagram and/or identified by ! in the
replacement parts list should be replaced only with
exact factory recommended replacement parts. The
use of unauthorized substitute parts may create
shock, fire, X-ray radiation, or other hazards.
To determine the presence of high voltage, use an
accurate high impedance HV meter connected
between the second anode lead and the CRT dag
grounding device. When servicing the High Voltage
System, remove static charges from it by connecting a
10k ohm resistor in series with an insulated wire (such
as a test probe) between the picture tube dag and 2nd
anode lead (have AC line cord disconnected from AC
The picture tube used in this receiver employs integral
implosion protection. Replace with a tube of the same
type number for continued safety. Do not lift picture
tube by the neck. Handle the picture tube only when
wearing shatterproof goggles and after discharging the
high voltage completely. Keep others without
shatterproof goggles away.
When removing springs or spring mounted parts from the
tuner, tuner cluster or chassis, shatterproof goggles must
be worn. Keep others without shatterproof goggles away.
Before returning the receiver to the user, perform the
following safety checks:
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.
Replace all protective devices such as nonmetallic
control knobs, insulating fishpapers, cabinet backs,
adjustment and compartment covers or shields,
isolation resistor-capacitor networks, mechanical
To be sure that no shock hazard exists, a check for
the presence of leakage current should be made at
each exposed metal part having a return path to the
chassis (antenna, cabinet metal, screw heads,
knobs and/or shafts, escutcheon, etc.) in the
Plug the AC line cord directly into a 120V AC receptacle.
(Do not use an Isolation Transformer during these
checks.) All checks must be repeated with the AC line
cord plug connection reversed. (If necessary, a
nonpolarized adapter plug must be used only for the
purpose of completing these checks.)
If available, measure current using an accurate leakage
current tester. Any reading of 0.35mA or more is
excessive and indicates a potential shock hazard which
must be corrected before returning the receiver to the
If a reliable leakage current tester is not available, this
alternate method of measurement should be used.
Using two clip leads, connect a 1500 ohm, 10 watt
resistor paralleled by a 0.15 F capacitor in series with
a known earth ground, such as a water pipe or conduit
and the metal part to be checked. Use a VTVM or
VOM with 1000 ohms per volt, or higher, sensitivity to
measure this AC voltage drop across the resistor. Any
reading of 0.35 volt RMS or more is excessive and
indicates a potential shock hazard which must be
corrected before returning the receiver to the owner.
SPECIFIC SERVICE INSTRUCTIONS
1. REMOVAL OF ANODE CAP
Read the following NOTED items before starting work.
After turning the power off there might still be a potential
voltage that is very dangerous. When removing the
Anode Cap, make sure to discharge the Anode Cap's
Do not use pliers to loosen or tighten the Anode Cap
terminal, this may cause the spring to be damaged.
1. Follow the steps as follows to discharge the Anode Cap.
(Refer to Fig. 1-1.)
Connect one end of an Alligator Clip to the metal part of a
flat-blade screwdriver and the other end to ground.
While holding the plastic part of the insulated Screwdriver,
touch the support of the Anode with the tip of the
A cracking noise will be heard as the voltage is discharged.
Flip up the sides of the Rubber Cap in the direction of the
arrow and remove one side of the support.
(Refer to Fig. 1-2.)
GND on the CRT
GND on the CRT
3. After one side is removed, pull in the opposite direction to
remove the other.
Take care not to damage the Rubber Cap.
1. Clean the spot where the cap was located with a small
amount of alcohol. (Refer to Fig. 1-3.)
Location of Anode Cap
Confirm that there is no dirt, dust, etc. at the spot where
the cap was located.
Arrange the wire of the Anode Cap and make sure the
wire is not twisted.
Turn over the Rubber Cap. (Refer to Fig. 1-4.)
4. Insert one end of the Anode Support into the anode button,
then the other as shown in Fig. 1-5.
Confirm that the Support is securely connected.
Put on the Rubber Cap without moving any parts.
NOTE FOR THE REMOVAL OF MAIN PCB
Remove the bindings of Fig. 1 and Fig. 2. After the unplugging of all connectors, remove Main PCB.
Note : When installing of the Main PCB, bind them as they were bound.
Cut the unnecessary section of the binding band.
