Service Adjustments

Following adjustments are not required to readjust when replacing the memory IC.

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 24.0 KV and 26.5 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 28.0 KV at zero beam current.

If reading is not within range, check horizontal circuit.

No high-voltage adjustment is provided on this chassis.
