IMPORTANT SERVICE SAFETY INFORMATION

- 2 -

Operation of receiver outside of cabinet or with 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 connecting ground lead
connections between chassis, escutcheon, picture tube dag
and tuner cluster when operating 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.

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 25 kV 

1.0kV at zero beam current with a line voltage of 120V AC.
Higher voltage may also increase possibility of failure in HV
supply.

PROTECT YOUR CUSTOMER

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. Replace all protective devices such as non-metallic control knobs,
insulating fishpapers, cabinet backs, adjustment and compartment covers
or shields, isolation resistor capacitor networks, mechanical insulators, etc.

3. 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 following manner.

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. (Use
Standard Item No. 25086,21641) Any reading of 0.4 mA or more is
excessive and indicates a potential shock hazard which must be corrected
before returning the receiver to the owner.

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 MF 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 0.61 volt RMS or more is excessive and indicates a potential
shock hazard which must be corrected before returning the receiver to the
owner.

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 or identified by the safety mark 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-radiation or other hazard.

To determine the presence of high voltage, use an accurate
high impedance HV meter connected between second anode
lead and the CRT dag grounding device. When servicing the
High Voltage System remove static charge from it by connecting
10K ohm resistor in series with an insulated wire (such as a
test probe) between picture tube dag and 2nd anode lead (AC
line cord disconnected from AC supply).

The picture tube used in this receiver employs integral implosion
protection. Replace with tube of the same type number for
continued safety. Do not lift picture tube by the neck. Handle the
picture tube only when wearing shatter-proof goggles and after
discharging the high voltage completely. Keep others without
shatter-proof goggles away.

When removing springs or spring mounting parts from tuner,
tuner cluster or chassis, shatter-proof goggles must be worn.
Keep others without shatter-proof goggles away.

INSTALLATION AND SERVICE INSTRUCTION

CAUTION: Use an isolation transformer when performing any service on this chassis.
SHUTDOWN CIRCUIT: When the high voltage rises, there are simultaneous voltage increase

developed at terminal 6 of the Horizontal Output Transformer ( T671 ) and applied to pin 29 of IC301. If
excessive high voltage is produced, the increased voltage developed exceeds the rating of zener diode
D552 causing the Horizontal Oscillator to stop functioning and the high voltage system to shut down.

COLOR PURITY ADJUSTMENT

For best results, it is recommended that the purity adjustment be made in the final receiver location. If
the receiver will be moved, perform this adjustment with it facing East.
The receiver must have been operating 15 minutes prior to this procedure and the face plate of the CRT
must be at room temperature. The following procedure is recommended while using a Dot/Bar
Generator.

1. Check correct location of all neck components. ( Refer to Figure 3 )

2. Rough -in the static convergence at the center of the CRT, as explained in the static convergence
procedure.

3. Set the Contrast control to minimum position and Brightness control as far maximum as possible

without causing the picture to “bloom”.

4. Apply green raster signal from Dot/Bar Generator to receiver.

5. Loosen the deflection yoke clamp screw and pull the deflection yoke toward the rear of the CRT.

6. Begin the following adjustment with the tabs on the round purity magnet rings set together. Slowly
separate the two tabs while at the same time rotating them to adjust for a uniform green vertical
band at the center of the CRT screen.

7. Carefully slide the deflection yoke forward to achieve green purity (Uniform green screen).

NOTE: Center purity is obtained by adjusting the tabs on the round purity magnet rings. Outer edge
purity is obtained by sliding the deflection yoke forward.

8. Check for red and blue field purity by applying red and blue raster signal alternately from Dot/Bar

Generator to receiver. Repeat steps 2 through 7, if required.

9. Tighten deflection yoke clamp screw.

10. Perform BLACK AND WHITE ADJUSTMENT procedure.

( CW : clockwise, CCW : counterclockwise )

FIG. 3

- 7 -

STATIC CONVERGENCE ADJUSTMENT ( Refer to Figure 3 and 4 )

IMPORTANT: Before proceeding, make sure the location of the convergence magnet assembly on the
neck of the CRT is as shown in Figure 3. The rear edge of this assembly must be positioned 65 mm
from the tip of the CRT base. If not properly positioned, convergence adjustment may be difficult, if not
impossible.

1. Apply dot or crosshatch pattern from Dot/Bar Generator to receiver. Reduce setting of Brightness
and/or Contrast controls to eliminate any blooming in pattern.

2. Observe the blue and red pattern appearing on the CRT screen. Locate the 4 pole magnet rings
and separate their adjusting tabs approximately the width of one tab.

3. Now rotate this pair of magnet rings as a unit without re-adjusting the spacing between the tabs.
This will minimize the separation between the blue and red dots (lines).

4. If the blue and red dots are not completely converged at this point, readjust the spacing between the
two tabs to complete convergence of the blue and red dots (lines), thus producing magenta dots
(lines).

5. If necessary, repeat step 2, 3 and 4 until proper convergence is achieved.

6. Observe the magenta (B/R) and green pattern now appearing on the CRT screen.

7. Locate the 6 pole magnet rings and separate their adjusting tabs approximately the width of one tab.

8. Rotate this pair of magnet rings as a unit without re-adjusting the spacing between the tabs. This
will minimize the separation between the magenta (B/R) and green dots ( lines).

9. If the magenta and green dots (lines) are not completely converged at these points, readjust the

spacing between the two tabs to complete convergence of the magenta and green dots (lines).

10. If necessary, repeat step 7, 8 and 9 until proper convergence is obtained.

To prevent accidental mis-adjustment of the magnets, apply a stripe of paint across all six rings and
onto the neck of the CRT.

FIG. 4

DYNAMIC CONVERGENCE ADJUSTMENT ( Refer to Figure 5)

Dynamic convergence (convergence of the three edges of the CRT screen) is accomplished by proper
insertion and positioning of three rubber wedges between the edges of the deflection yoke and funnel of
the CRT. This is accomplished in the following manner.

1. Turn the receiver ON and allow it to warm up for 15 minutes.

2. Apply crosshatch pattern from Dot/Bar Generator to receiver. Observe spacing between lines around

edges of CRT screen.

3. For the misconvergence shown in Figure 5 ( A ), tilt the deflection yoke down and insert wedge A
between deflection yoke and CRT.

4. For the misconvergence shown in Figure 5 ( B ), tilt the deflection yoke up and insert wedge B
between deflection yoke and CRT.

5. For the misconvergence shown in Figure 5 ( C), tilt left side of the deflection yoke and slightly insert
wedge C between deflection yoke and CRT. Then, deeply insert wedges A and B between deflection
yoke and CRT.

6. For the misconvergence shown in Figure 5 ( D ), tilt right side of the deflection yoke and deeply insert
wedge C between deflection yoke and CRT. Then, slightly insert and/or extract wedges A and B
between deflection yoke and CRT.

7. Alternately change spacing between and depth of insertion of the three wedges until proper dynamic
convergence is obtained.

8. Use a strong adhesive tape to firmly secure each of the three rubber wedges to the funnel of the
CRT.
