ABSTRACT:
A horizontal deflection high-voltage circuit using the diode modulation horizontal deflection circuit is provided with a means detecting the high voltage output from the flyback transformer for supplying the input terminal of the flyback transformer with a control signal which controls the high voltage to be kept constant and a means detecting a variation in the control signal for supplying one end of a modulation coil with a control signal which controls the horizontal deflection current to be kept constant, whereby a horizontal deflection high-voltage circuit practically free from irregularity of adjustment and deterioration due to aging is provided.
