SCHEMATIC DIAGRAMS
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
29.0KV AT ZERO BEAM CURRENT AT 120 VOLTS AC LINE, AND MUST NOT EXCEED 30.0KV UNDER ANY
OPERATING CONDITION. SEE HIGH VOLTAGE CHECK ON PAGE 8.

NOTES ON SCHEMATIC DIAGRAMS
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 VHF channel 5, all controls at normal. Line voltage at 120
volts. Some voltages may vary with signal strength.
4. Waveforms were taken with color-bar signal and controls adjusted for normal picture. Waveforms marked
with an
✽
may vary with signal strength.
5. The Symbol indicates a fusible resistor, which protects the circuit from possible short circuits.
WAVEFORMS
NOTE: Waveforms were taken with color-bar signal and the controls adjusted for normal picture.
