Abstract
In a vertical sawtooth generator of a D.C. coupled vertical deflection circuit, a vertical deflection amplifier generates a sawtooth signal. Magnitudes of the sawtooth signal in first and second instants of its trace period are determined in accordance with first and second D.C. signals, respectively. The first and second D.C. signals are adjusted during service to control the raster height and the raster centering such that while the raster height is adjusted, raster centering is not significantly affected, and vice versa.
