DESCRIPTION OF SCHEMATIC DIAGRAM

NOTES:
1. The unit of resistance "ohm" is omitted
H
(K:1000 ohms, M:1 Meg ohm).
2. All resistors are 1/8 watt, unless otherwise noted.
3. All capacitors are µ F, unless otherwise noted P: µµ F.
4. (G) indicates ± 2% tolerance may be used.
VOLTAGE MEASUREMENT CONDITIONS:
1. All DC voltages are measured with DVM connected
G
between points indicated and chassis ground, line
voltage set at 120V AC and all controls set for normal
picture unless otherwise indicated.
2. All voltages measured with 1000 µ V B&W or Color
signal.

WAVEFORM MEASUREMENT
1. Photographs taken on a standard gated color bar
signal, the tint setting adjusted for proper color. The
wave shapes at the red, green and blue cathodes of
the picture tube depend on the tint, color level and
picture control.
2. indicates waveform check points (See chart,
waveforms are measured from point indicated to
chassis ground.)
