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 within 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.
