Abstract
PURPOSE:To prevent the abonormal high tension from being applied to a Braun tube by stopping the horizontal oscillation of a horizontal output circuit at an anomaly time of this circuit. CONSTITUTION:When anomaly has occurred in horizontal output circuit 26, the pulse voltage of coil 22 of fly-back transformer 20 is increased, and therefore, detection transistor 29 is turned off. Then, horizontal oscillation transistor 8 becomes a saturation state, and the oscillation output disappeara. As a result, the operation of horizontal output circuit 26 is stopped to stop the generation of a high tension.
