Abstract

PURPOSE:To eliminate the need for a power supply transformer for standby for remote control, by picking up a part of an output from a horizontal output driving transformer and applying the output as the power supply for a remote control circuit. CONSTITUTION:A ternary winding 12 is provided for a horizontal drive transformer 10, a part of a horizontal output is rectified at a diode 20 and applied to a receiver 15 and a signal processing circuit 16 as a power supply for remote control. An output of a horizontal oscillation circuit 6 drives the transformer 10 via a horizontal drive transistor 9 from a horizontal drive circuit 8. The output of a secondary winding 11 of the transformer 10 is applied to a horizontal output transistor 13 via a coctact 19 of a relay 18 to give a drive pulse to a flyback transformer 5. On the other hand, an output of the circuit 16 energizes the relay 18 via a transistor 17 and the contact 19 switches the circuit of the transistor 13.
