ABSTRACT:
In a multiple scanning type television receiver in which a horizontal frequency of a horizontal deflection circuit and a capacity value of an S-shaping capacitor are both switched by an output signal from a frequency to voltage converter which detects a horizontal frequency of an input signal and converts the same to a voltage changing in response to the frequency, a horizontal deflection circuit of a multiple scanning type television receiver being characterized in that a detector is provided for detecting said switching time point and during a transient period obtained from said detector, the power source of said horizontal deflection circuit is cut off.
