In a projection television receiver, a common switch mode power supply energizes the convergence circuits, and other load circuits of the projection television receiver. In normal operation, a switch couples a supply voltage produces in the common switch mode power supply to the convergence circuits. When, as a result of a fault, a supply current in the convergence circuits is excessive, the common switch mode power supply is decoupled from the convergence circuits and other load circuits remain energized and operative.
