Abstract
A convergence method for color television receiver comprises the steps of emitting a test signal from a control circuit to a first convergence channel to generate a current of a predetermined intensity in a convergence coil assigned thereto. The control circuit emitting a zero signal to the other convergence channels to generate zero current in the assigned convergence coils. Measuring and comparing with a reference potential a potential at a reference point of each convergence coil of channels driven by the zero signal. Generating a reference signal responsive to the comparison step b), for each case for the relevant convergence channel and coupling to the control circuit. Repeating steps a) to c) for each convergence channel, the convergence channels being driven in an alternating fashion one after another once in each case by a test signal.
