SAFETY PRECAUTIONS

NOTICE: Comply with all cautions and safety-related

notes located on or inside the cabinet and on the chasis or
picture tube.

WARNING: Since the chasis of this receiver is connected
to one side of the AC power supply during operation,
whenever the receiver is plugged in, service shoul d not be
attempted by anyone unfamiliar with the precautions
necessary when working on this type of receiver.

The following precautions should be observed:

1. Do not install, remove, or handle the picture tube in any
manner unless shatterproof goggles are worn. People
not so equipped should be kept away from the picture
tube while handling.

2. When service is required, an isolation transformer
should be inserted between power line and the receiver

before any service is performed on a “HOT” chassis
receiver.

3. When replacing a chassis in the receiver, all protective
devices must be put back in place, such as barriers,
nonmetallic knobs, adjustment and compartment
covershields, isolation resistors, capacitors, etc.

4. When service is required, observe the original lead
dress in the high voltage circuitry area.

Leakage Current Hot Check

Plug the AC cord directly into a 120V AC 60Hz outlet (do
not use an isolated transformer for this check). Turn the
AC power ON. Using a Leakage Current Tester
(Simpson’s Model 229 or equivalent), measure for current
from all exposed metal parts of the cabinet (antennas,
screwheads, overlays, control shafts, etc.). Any current
measured must not exceed 0.5 milliamps.

5. Always use the manufacturer’s replacement
components. Critical components as indicated on the
circuit diagram should not be replaced by another
manufacturer’s. Furthermore, where a short circuit has
occurred, replace those components that indicate
evidence of overheating.

6. Before returning a serviced receiver to the customer, the
service technician must thoroughly test the unit to be
certain that it is completely safe to operate without
danger of electrical shock, and be sure that no
protective device built into the receiver has become
defective, or inadvertently defeated during servicing.

Therefore, the following checks should be performed for
the continued protection of the customer and service
technician.

Leakage Current Cold Check

With the AC plug removed from the 120V AC 60Hz source,
place a jumper across the two plug prongs. Turn the AC
power switch ON. Using an insulation tester (DC500V),
connect one lead to the jumpered AC plug and touch the
other lead to each exposed metal part (antennas,
screwheads, metal overlays, control shafts, etc.),
particularly any exposed metal part having a return path to
the chassis should have a minimum resistor reading of

0.24MΩ and a maximum resistor reading of 12MΩ. Any

resistance value below or above this range indicates an
abnormality which requires corrective action. An exposed
metal part not having a return path to the chassis will
indicate an open circuit.

AC LEAKAGE TEST
ANY MEASUREMENTS NOT WITHIN THE LIMITS

OUTLINED ABOVE ARE INDICATIVE OF A
POTENTIAL SHOCK HAZARD AND MUST BE
CORRECTED BEFORE RETURNING THE
RECEIVER TO THE CUSTOMER.

High voltage

This receiver is provided with a hol d down circuit for clearly
indicating that voltage has increased in excess of a
predetermined value. Comply with all notes described in
this service manual regarding this hold down circuit when
servicing, so that this hold down circuit is operated
correctly.

Serviceman Warning

With minimum BRIGHTNESS, CONTRAST,
SHARPNESS, and COLOR, the operating high voltage in
this receiver is lower than 28.30kV ±1.25kV. In case any
component having influence on the high voltage is
replaced, confirm that high voltage with minimum
BRIGHTNESS, CONTRAST, SHARPNESS, and COLOR
is lower than 28.30kV ±1.25kV. To measure high voltage
use a High Impedance High Voltage meter. Connect (-) to
chassis earth and (+) to the CRT ANODE button. (See the
connection diagram on page 4.)

Note: Turn power switch OFF without fail before the
connection to the Anode Button

Service Notes

IMPORTANT: To protect against possible damage to

the solid state devices due to arcing or static
discharge, make certain that all gro und wires and CRT
DAG wire are securely connected.

Equipment needed to check the disabled circuit:

1. Voltmeter (0 - 200V scale)

2. High Voltage Meter (0- 50kV)

CAUTION: The power supply circuit is above earth
ground and the chassis cannot be polarized. Use an
isolation transformer when servicing the Receiver to
avoid damage to the test equipmen t or to the chassis.
Connect the test equipment to the proper ground ( ) or

( ) when servicing, or incorrect voltages will be
measured.

WARNING: This Receiver has been designed to mee t
or exceed applicable safety and X-ray radiation
protection as specified by government agencies and
independent testing laboratories.

Purity and Convergence Procedure

Adjustment is necessary only if the CRT or the
deflection yoke is replaced or if the setting was
disturbed. The complete procedure consists of:

1. Vertical Raster Shift Adjustment. (Only for Models

with Purity/Convergence Assembly with 4 Pairs
of Rings).

2. Initial static convergence.

3. Setting the purity.

4. Final static convergence.

When the CRT or the Yoke is Replaced

Place the yoke on the CRT neck (do not tighten
the clamp).

For a 2-piece assembly (see Fig. 4):

Position purity/convergence assembly as shown and
tighten clamp snugly. Remove the hot-melt glue seal
on assembly and position like tabs of purity device

together at 12 o’clock to reduce its magnetic field
effect.

R&B Convergence Rings

R&B&G Convergence Rings

For a 1-piece assembly (see Fig. 7):

Position like tabs of purity devices together at 12

o’clock to reduce any magnetic field effect. (For better
results, note part number and loo k for specifi cations at
Service Center)

Figure 7. Positioning of Purity/Convergence

Assembly (1-piece assembly)

For either assemblies:

Turn the Receiver ON. Operate the Receiver for 60
minutes using the first Purity Check field (white screen)
to stabilize the CRT.

Fully degauss the Receiver by using an external
degaussing coil .

Slide the deflecti on yoke bac k and forth on the nec k of
the CRT until it produces a near white, uniform raster.

Apply a green pattern wi th a horizontal line, a djust the
Deflection Yoke so that has no tilt, then secure it.
Adjust center line of the pattern with the mechanical
center of the CRT, this center is determined by two
marks at the side edges of the screen. To adjust the
line, once the vertical raster shift tabs are place at 3
o’clock to reduce its magnetic field effect (see Fig. 5
and Fig. 6) open the tabs the same angle from the
center, until the center line of the pattern becomes a
straight line, ce ntered with the mar ks of the CRT. (see
Fig. 8)

Initial Center Static Convergence

NOTES:

1. CRT warm up with white screen
(three guns activated) is needed
to stabilize the shadow mask
expansion.

2. Initial center static convergence
(roughly centers three gun
beams) is required in order to
perform purity adjustment.

Figure 9. Green Raster Adjustment

Green Raster

Connect a dot/cross hatch generator to the Receiver
and tune in a signal. Observe misconvergence at
center of the screen only.
Adjust the R&B pole magnets; by separa ting tabs and
rotating to converge blue with red.
Adjust the R&B and R&B&G pole magnets: by
separating tabs and rotating to converge blu e and red
(magenta) with green.

Note: Precise convergence at this point is

not important.

Purity Adjustment

When the Receiver is in the Serviceman Mode for
making electronic adjustments, press the Recall button
on the Remote Control to enter Pu rity Check. (See the

Service Adjustments Electronic Controls

procedure).
Operate the Receiver for 60 minutes using the first
Purity Check field (white screen) to stabilize the CRT.
Fully degauss the Receiver by using an external
degaussing coil.
Press the Recall button on th e Remote Control again
until the Purity Check (green screen) appears.

For a 2-piece assembly (see Fig. 4):
Loosen the deflection y oke clamp sc rew and move the
deflection yoke back as close to the purity magnet

as possible.
Adjust the Purity rings to set the vertical green raster
precisely at the center of the screen (see Fig. 9).

Final Convergence Procedure (see Fig. 10

through Fig. 12):

Note: Vertical size and focus adjustments must be
completed prior to performing the convergence
adjustment. Connect a dot pattern generator to the
Receiver. The Brightness level should not be higher
than necessary to obtain a clear pattern.

Converge the red and the blue dots at the center of the
screen by rotating the R&B pole Static Convergence
Magnets.
Align The converged red/blue dots with th e green dots
at the center of th e s c reen by rotating the R&B& G po le
Static Convergence Magnets. Melt wax with soldering
iron to reseal the magnets.
Slightly tilt ve rtical ly and horizon tally (d o not rotate) the
deflection yoke to obtain a good overall convergence.
If convergence is not reached at the edges, insert
permalloy (see following section) from the DY corners
to achieve proper convergence. Recheck for purity and
readjust if necessary.
After vertical adjustment of the yoke, insert wedge at

11 o’clock position, then make the horizontal
tilt adjustment.
Secure the deflection yoke by inserting two side
wedges at 3 and 7 o’clock positions.
Apply adhesive between tab (thin portion) of wedge
and CRT and place tape over the tab to secure to
the CRT.

Permalloy Convergence Corrector Strip
(Part No. 0FMK014ZZ)

Slowly move the deflec tion yoke forward until the best
overall gre en screen is displayed.

For a 1-piece assembly (see Fig. 7):
Slowly move the deflection yoke and purity rings

assembly toward the CRT board and adjust the purity
magnet rings to set vertical green raster at center of
screen (see Fig. 9).
Gradually move the deflection yoke & purity rings
forward and adjust for best overall green screen.

Continue from here for either assemblies:

Tighten the deflection yoke clamp screw.
Press the Recall button on th e Remote Control again
until the purity check (blue screen) and (red screen)
appear and observe that good purity is obtained on
each respective field.
Press the Recall button on th e Remote Control again
until Purity chec k (white screen ) appears. Obs erve the
screen for uniform white. If purity has not been
achieved, repeat the above procedure.

This strip is use d in some sets to matc h the yoke and
CRT for optimum convergen ce. If the yoke or CRT is
replaced, the strip may not be required.
First converge the set without the strip and observe
the corners.

If correction is needed:

1. Place strip between CRT and yoke, in quadrant
needing correction. Slowly move it around for
desired results.

2. Press adhesive tightly to the CRT and secure
with tape.
