ABSTRACT OF THE DISCLOSURE A system for compensating for mislanding of electron beams on the screen of a color cathode ray tube resulting from thermal expansion of a beam selecting structure in the tube which comprises electromagnetic devices provided on the tube for producing respective magnetic fields by means of a current supplied thereto so as to change the paths of the electron beams passing through the beam selecting structure, and a circuit for supplying to the electro-magnetic devices a first correcting current varying substantially in response to changes in the temperature of the beam selecting structure and a second correcting current varying in accordance with a predetermined change in value during the initial period of the operating condition of the tube.
