Abstract: -11-                RCA 75,604 ABSTRACT OF THE DISCLOSURE In a remote controlled color television receiver, the television receiver power supply is responsive to the state of an on/off command signal.  A DC supply voltage is applied to an input terminal of the power supply during both states of the on/off command signal, with the power supply developing an operating voltage at an output terminal only during the on-state of the command signal.  A relay type switch is coupled to a degaussing winding and a source of alternating polarity voltage.  The switch is responsive to the presence of the operating voltage and applies the alternating polarity voltage to the degaussing winding to generate degaussing current during the occurrence of, illustratively, the on-state of the command signal.
