ABSTRACT:
Apparatus for reducing transient beam current conduction of a kinescope of a television receiver. Means are included for providing control signals representative of transient increases in beam current of predetermined duration. The magnitude of successively recurring control signals is altered (e.g., reduced) in progressive increments. The altered magnitude control signals are coupled to the kinescope to reduce the conduction of the kinescope in accordance with the magnitude of the control signals, so that the visually perceived effect of the operation of the apparatus is less pronounced.
