消磁回路。 A switching element is connected in series in a resonant circuit consisting of a capacitor and a degaussing coil, which start charging when the power is turned on, and a drive signal is applied to the control electrode of this switching element, which rises after charging of the capacitor is completed and falls after a certain period of time. In such a degaussing circuit, the drive signal is generated only when a predetermined period of time has elapsed from the time when the power supply was cut off immediately before, and the fall time of the drive signal is earlier than the time when the picture tube outputs an image. A degaussing circuit for a color television receiver, characterized in that the degaussing circuit is set to
