  • Measurement-free G2 calibration of color picture tubes
    Patent number: 6433827
    Abstract: A method for calibrating a screen grid voltage of the color picture tube in a color television set having automatic cut-off regulation. The method comprises the steps of, changing a normal operating potential at control electrodes of the color picture tube; adjusting the screen grid voltage about a value until values causing a fly-back line to be alternately visible and extinguished converge on the value; and, resetting the normal operating potential at the control electrodes of the color picture tube.
