ABSTRACT OF THE DISCLOSURE A degaussing circuit for a video apparatus incorporates circuitry that controls various aspects of the degaussing operation. The control circuitry causes the degaussing current to be terminated after a period of time to eliminate the flow of residual degaussing current. The control circuit also causes the degaussing circuit to be reset, to enable degaussing to occur. The control circuit also prevents degaussing from occurring after a brief interruption of power to the video apparatus.
