ABSTRACT:
A color television receiver with luminance and chrominance signal channels includes an automatic kinescope beam current limiter, an automatic white level drive control network, and an automatic black level bias control network. A switching network is timed to operate such that a control signal developed by the beam current limiter is coupled to the luminance and chrominance channels during normal picture intervals, decoupled from at least the luminance channel during white level drive control intervals, and coupled to at least the chrominance channel during black level bias control intervals.
