The purpose of this invention is to simplify the power circuit in providing the convergence correction for the 3 colors by digital non-linear image mapping circuit at video signal level, (no power dissipation) and to provide the vertical trapezium correction with magnets on the yokes (no power dissipation) and advantageously the common North-South correction with a single power amplifier for the three color tubes.
