To provide a television receiver having no image strain even if there is a change in high voltage.
The television receiver comprises a CRT for displaying an image, a vertical deflection circuit for generating a vertical drive signal for vertically deflect an electron beam irradiated on the screen of the CRT, a horizontal deflection circuit for generating a horizontal drive signal for horizontally deflecting the electron beam irradiated on the CRT screen, and a horizontal amplitude correction circuit for correcting the amplitude of the horizontal drive signal based on the vertical drive signal. By correcting the amplitude of the horizontal drive signal by the horizontal amplitude correction circuit, image strain generated at both ends of the CRT screen can be corrected. The horizontal amplitude correction circuit 8 is equipped with a clip circuit 20 for limiting the amplitude of the vertical drive signal to a prescribed value.
