ABSTRACT:
An intermediate tap 31 is provided on a vertical deflection coil 22 of a deflection yoke and the intermediate tap is connected to a chassis ground through a high-pass filter 32 which can pass only a ringing current to form a current path, thereby the the ringing current is prevented from passing through the vertical deflection coil 22 so that the raster ringing is substantially reduced.
