The invention relates to a method for convergence correction in a television set, and to a television set, in particular a projection television set, having a monochromatic tube for each of the three primary colours, red, green and blue, whose images can be projected on a screen. Each tube has an associated correction device, which comprises a convergence circuit. The fundamental idea of the method according to the invention consists in the manufacturer already taking account of differences which result from convergence setting by means of an image acquisition system on the part of the manufacturer and such setting by means of optical sensors in the set. In this way, mechanical tolerances and also optical imaging defects can be taken into account equally with little outlay. As a result, it is possible for the user to obtain improved convergence setting.
