Abstract
Three vertical deflection windings of corresponding three deflection yokes that are mounted on three cathode ray tubes of a projection video are coupled in series through corresponding three connector pairs. Three horizontal deflection windings of the corresponding three deflection yokes are coupled in parallel through the corresponding three connector pairs. When any of the three connector pairs is left disengaged, a disabling signal that is indicative of a loss of a vertical deflection current in the series coupled vertical deflection windings is generated. The disabling signal is coupled to a corresponding video driver of each of the cathode ray tubes for providing beam current blanking to protect the screens of the tubes against a screen burn damage.
