信機。 a switching regulator comprising a converter transformer, an oscillation transistor connected to the primary side of the converter transformer, and a control circuit that controls the base current of the oscillation transistor;
In a television receiver that is provided with a horizontal deflection circuit that inputs the output of the switching regulator as a power source, and a protector circuit that stops the operation of the horizontal deflection circuit, the protector circuit and the switching regulator are controlled. An abnormality detection circuit having a photocoupler is provided between the converter transformer and the converter transformer, and when an abnormality occurs on the secondary side of the converter transformer, a stop signal output from the protector circuit is sent to the control circuit via the abnormality detection circuit, and the oscillation operation of the oscillation transistor is controlled. A television receiver characterized by controlling.
