ABSTRACT:
A video display apparatus incorporates a start-up and control circuit that is responsive to a bilevel signal indicative of the desired operating state of the video display apparatus. One state of the bilevel signal is effective to permit operation of the horizontal deflection circuitry and to generate a gating pulse for a voltage regulator circuit. The other state of the bilevel signal disables the horizontal deflection circuit which in turn disables the video display apparatus load circuits.
