Abstract

PURPOSE:To prevent surely the generation of an abnormal high tension by making a horizontal output circuit into a self-oscillation state at an anomaly time of this circuit in a TV receiver. CONSTITUTION:When the secondary-side voltage of fly-back transformer 10 is increased and the pulse voltage of coil 14 is detected by detector 21, switch 20 is turned off and the negative pulse voltage is applied to the base of horizontal drive transistor TR2. Then, TR2 is turned on in time T1, when TR2 should be turned off normally, by the voltage applied in time T2 by coil 12. When TR2 is turned on forcedly in the off time, horizontal output TR5 is changed to be turned off from an onstate, and a fly-back pulse is generated. Therefore, TR2 is turned off again; and when the pulse time is over, TR2 is turned on. By repeating this operation, horizontal output circuit 17 becomes a self-oscillation state, and a repeated frequency is increased, so that the high tension applied to CRT13 may be lowered.
