Abstract
A vertical deflection circuit includes a first pin which receives a forward scanning voltage having a first level and a first frequency. During a flyback period a second pin receives a flyback voltage having a second level higher that the first level and a second frequency higher than the first frequency. A third voltage source provides a first pulse. A switch means selectively couples the first pin and the third voltage source in response to a vertical blanking signal. The vertical blanking signal is differentiated to provide a differentiated signal and a voltage divider applies the differentiated signal to the switch to apply the first pulse to the first pin.
