Abstract
There is provided a stabilizing circuit for stabilizing the horizontal picuture size on the display of a television receiver, wherein a video signal containing a horizontal synchronizing signal having a horizontal scanning frequency is inputted. Said stabilizing circuit comprises: a horizontal output circuit for receiving a signal sychronizing with said synchronizing signal and corresponding to said horizontal scanning frequency, and for supplying a horizontal deflection current; a power source for supplying an electric power to the above horizontal output circuit; a control transistor connected between the power source and the horizontal output circuit; an output voltage generating circuit for generating an output voltage corresponding to an output pulse from the horizontal output transistor; a multiplier for multiplying the output from the control transistor with a predetermined multiple; an adder for adding together the output from the multiplier and the output from the output voltage generating circuit, thereby controlling the control transistor by virtue of the output from the adder.
