HIGH VOLTAGE CHECK

Note: +B (+130V) Voltage Check and Grayscale Adjustment must

be completed before attempting High Voltage Check.

1. Connect high voltage voltmeter negative lead to ground, and

c lead to anode of picture tube.

2. Tune receiver to an active channel and confirm TV is

operating properly.

3. Maximize the beam current by adjusting the contrast and

brightness controls to maximum. Confirm high voltage is with-
in 20.0 KV and 22.0 KV at maximum beam current.

4. Eliminate the beam current by adjusting the contrast and

brightness controls to minimum. Confirm high voltage does
not exceed 23.5 KV at zero beam current.

If reading is not within range, check horizontal circuit.

No high-voltage adjustment is provided on this chassis.

C436

HORIZ. WIDTH ADJUSTMENT

1. Receive a monochrome circular pattern.
2. Set the brightness and contrast to maximum.
3. If the picture is too wide, remove

“C436”

on the main unit.
