Abstract

A deflection generator (21) of a television receiver includes a trace switch (27) that during normal mode of operation is switched at a deflection rate to generate scanning current in a deflection winding (LH). The deflection generator includes a retrace capacitance (CR) for forming a retrace resonant circuit with the deflection winding to produce a retrace pulse voltage. A load circuit (at Vb) is coupled to the deflection generator and is energized by the retrace pulse voltage during normal operation. A remote control circuit (30) develops a remote ON-OFF command signal. A standby circuit (Q2) is series coupled with the deflection generator (21) and is responsive to a remote ON-OFF command signal for producing substantially a short circuit through the trace switch (27) upon receipt of the OFF-state of the command signal. The retrace pulse voltage then collapses and places the load circuit in a standby mode of operation. <IMAGE>
