SAFETY PRECAUTIONS
WARNING: The chassis of this receiver has a floating ground
with the potential of one half the AC line voltage in respect to
earth ground. Service should not be attempted by anyone not
familiar with the precautions necessary when working on this
type of equipment.
The following precautions must be observed:
1. An isolation transformer must be connected in the power line
between the receiver and the AC line before any service is
performed on the receiver.
2. Comply with all caution and safety-related notes provided on
the side of the cabinet, inside the cabinet, on the chassis, and
the picture tube.
3. When replacing a chassis in the cabinet, always be certain
that all the protective devices are installed properly, such as
control knobs, adjustment covers, shields and barriers.
DO NOT OPERATE THIS TELEVISION RECEIVER
WITHOUT THE PROTECTIVE SHIELD IN POSITION AND
PROPERLY SECURED.
4. Before replacing the back cover of the set, thoroughly inspect
the inside of the cabinet to see that no stray parts or tools
have been left inside.
Before returning any television to the customer, the
service technician must perform the following safety checks
to be sure that the unit is completely safe to operate without
danger of electrical shock.
ANTENNA COLD CHECK
Remove AC plug from the 220 VAC outlet and place a jumper
across the two blades. Connect one lead of an ohmmeter to the
jumpered AC plug, and touch the other lead to each exposed
antenna terminal (UHF and VHF antenna terminals). The resistance must measure 10M ohm or over. Any resistance value
below this range indicates an abnormality which requires corrective action.
LEAKAGE CURRENT CHECK
Plug the AC line cord directly into a 220 VAC outlet. (Do not use
an isolation transformer for this check.) Use an AC voltmeter,
that has 5000 ohms per volt or more sensitivity. Connect a 2000
ohm 10 watt resistor, between a known good earth ground
(water pipe, conduit, etc.) and all exposed metal parts of the
cabinet (antennas, earphone jack, screwheads, metal overlays,
control shafts, etc.). Measure the AC voltage across the 2000
ohm resistor.
The AC voltage should not exceed 1400 mV. A reading exceeding 1400 mV indicates that a dangerous potential exists. The
fault must be located and corrected. Repeat the above test with
the receiver power plug reversed.
NEVER RETURN A RECEIVER TO THE CUSTOMER
WITHOUT TAKING THE NECESSARY CORRECTIVE
ACTION.
X-RADIATION PRECAUTION
The primary source of X-RADIATION in solid-state receivers is the
picture tube. The picture tube is specially constructed to limit X-Ray
emission. For continued X-RADIATION protection, the replacement
tube must be the same type as the original (including the suffix letter in the part numbers). Excessive high voltage may produce
potentially hazardous X-RADIATION. To avoid such hazards, the
high voltage must be maintained within specific limits. Refer to the XRADIATION WARNING NOTE on the CHASSIS SCHEMATIC in
this service manual for specific high voltage limits. If the high voltage exceeds specified limits, check the components specified on
the chassis schematic diagram and take the necessary corrective
action. Carefully follow the instructions for the +B Voltage Check
and the High Voltage Check to maintain the high voltage within the
specified limits.
PRODUCT SAFETY NOTICE
When replacing components in a receiver, always keep in mind
the necessary product safety precautions. Pay special attention
to the replacement of components marked with a star (★) in the
parts list and in the schematic diagrams. To ensure safe product
operation, it is necessary to replace those components with the
exact same PARTS.
SAFETY INSTRUCTIONS
READING SHOULD NOT EXCEED 1400 mV.

11. Adjust the angle between the two purity magnet tabs to
center the vertical green belt in the picture tube. Do not
rotate tabs. See Figure 3.
12. Slowly slide the deflection yoke forward until a uniform
green screen is obtained.
13. Check the purity of the red and blue screens for uniformity.
Turn off other colors to check (use bias controls) or use
generator. If necessary, readjust the yoke position until all
screens are pure.
14. If bias controls and screen control were used to set purity,
reset Grayscale. Refer to Grayscale Adjustment on page 6.
15. Confirm that the yoke is not tilted. Tighten the yoke
mounting screw. Adjust convergence next.
CAUTION: Purity and Convergence adjustments have been made at the factory. Readjustments should be made

SERVICE HINTS
POWER FAILURE DETECTOR
This set is equipped with a Power Failure Detector function included in the CPU which checks for an abnormal condition in the
chassis power supplies, including the power supply derived from the Horizontal Output Transformer.
If, while the power is on, a failure is caused by any of the following that results in a low voltage supply, the CPU will turn the unit of f in
1.5 seconds to prevent unnecessary damage:
•
Failure within the power supply circuits.
•
A short circuit in the load side from the supply.
•
Stoppage of the Horizontal Output Oscillator caused by the X Radiation protection Hold-Down Circuit.
If, while the power is off, the power is switched on and any of these failures remains uncorrected, the CPU will shut off the power
within three seconds.
Check the following if the unit is turned off by the power failure detector.
1. Disconnect the AC power cord (120V AC line) for at least 10 seconds.
2. Connect a DC Voltmeter to the following TEST POINTS.
TJ6 5V
D429 Cathode 5V
3. Press the power key and check for the proper voltage supplies.
4. If any of these voltages is low, the power failure detector should turn the set off within three seconds.
5. Check all circuits listed above.
Note:This unit is equipped with a Power Surge Protection feature included in the CPU. If power Failure occurs three times within 15
minutes, the CPU will automatically stop functioning to help prevent secondary damage. (TV will not turn on by pressing the
power key.) To reset the operating programs within the CPU, disconnect the AC power cord for at least 10 seconds.

SCHEMATIC DIAGRAMS
VOLTAGE CHARTS
Note: Voltages were measured with color-bar signal and controls set for normal picture.
NOTES ON SCHEMATIC DIAGRAM
1. All resistance values in ohms K=1,000 M=1,000,000.
2. Unless otherwise noted on schematic, all capacitor values less than 1 are expressed in µF (Micro Farad), and the
values more than 1 are in pF.
3. Unless otherwise noted on schematic, voltage reading taken with VOM from point indicated to chassis ground.
Voltage reading taken using color bar-signal on VHF channel 5, all controls at normal. Line voltage at 220 volts.
Some voltages may vary with signal strength.
4. Waveforms were taken with color-bar signal and controls set for normal picture. Waveforms marked with an ✽ may
vary with signal strength.
5. Symbol indicates a fusible resistor, which protects the circuit from possible short circuits.
SERVICE NOTES:
1. When replacing parts on circuit boards, clamp the lead wires to terminals before soldering.
2. When replacing high wattage resistors on circuit board, keep the resistor body 10 mm (3/8”) from circuit board.
3. Keep wires away from high voltage and high temperature components.
PRODUCT SAFETY NOTICE
THE COMPONENTS DESIGNATED BY A STAR (★) ON THIS SCHEMATIC DIAGRAM DESIGNATE COMPONENTS
WHOSE VALUES ARE OF SPECIAL SIGNIFICANCE TO PRODUCT SAFETY. SHOULD ANY COMPONENT
DESIGNATED BY A STAR NEED TO BE REPLACED, USE ONLY THE PART DESIGNATED IN THE PARTS LIST. DO
NOT DEVIATE FROM THE RESISTANCE, WATTAGE AND VOLTAGE RATINGS SHOWN.
X-RADIATION WARNING NOTE
THIS TV CONTAINS CRITICAL PARTS TO PROTECT AGAINST X-RADIATION. NOMINAL 2ND ANODE VOLTAGE IS
26.5KV AT ZERO BEAM CURRENT AT 120 VOLTS AC LINE, AND MUST NOT EXCEED 28.0KV UNDER ANY
OPERATING CONDITION. SEE HIGH VOLTAGE CHECK ON PAGE 8.
