PURPOSE:To suppress the useless power consumption and to obtain the sufficient safety by stopping an output of a horizontal deflecting circuit, and also, stopping an output of a power source circuit, when abnormality of an anode voltage is detected. CONSTITUTION:When abnormality of an anode voltage is detected, since an output of a horizontal drive pulse is stopped by a protector circuit, a detecting transistor 40 is flipped to an OFF state and a control transistor 41 becomes an ON state, therefore, a control voltage of an H level from a remote control IC 38 is bypassed and a driving transistor 37 becomes an OFF state. Subsequently, supply of a commercial AC power by a power relay 36 is stopped, and as a result, an output of a power source circuit is stopped, and the power source supply to a voice system/video system circuit comes not to be executed. In such a way, when abnormality of the anode voltage is detected, the power consumption is suppressed, and the safety can be secured enough. |
