PURPOSE:To perform stable vertical synchronizing operation and to attain a stable picture, by superimposing a synchronizing signal component of a vertical deflection output signal on a vertical syncrhonizing signal via a capacitor, in a vertical deflector of a television receiver. CONSTITUTION:A terminal 18 appears a vertical syncrhonizing signal and a terminal 15 appears a vertical deflection output signal are connected with a capacitor 5 so as to superimpose the synchronizing signal component of a vertical deflection output waveform on the vertical synchronizing signal. Thus, the vertical synchronism is synchronized at one point and the picture is stabilized. Since the rise of the vertical synchronizing signal is made steep. the pulse width is sharpened and the amplitude of the vertical synchronizing signal itself is increased, the picture is stahilized by sincbronizing the vertical sinchronize signal at one point, even if noise is mixed in the vertical synchronizing signal. |
