A CRT protector circuit for detecting an overcurrent or an overvoltage to a CRT to protect the CRT. A detector circuit is provided for detecting the overcurrent and the overvoltage, and when such is detected an abnormality detection output from the detector circuit is supplied to a control circuit which in turn controls a horizontal output circuit. The operation of the horizontal output circuit, provided on a primary side of a flyback transformer is, instantaneously broken by the control circuit according to the abnormality detection output from the detector circuit. When the frequency of generation of the abnormality detection output becomes a predetermined value or more, the operation of the horizontal output circuit is continuously inhibited. Accordingly, when the abnormal condition is temporary, a normal high-voltage generating operation can be automatically restored.
