In a top-bottom pincushion correction circuit having a saturable reactor with a control winding coupled to a source of deflection current at a horizontal scan frequency and an output winding coupled to a source of deflection current at a vertical scan frequency, a means coupled to the control winding unbalances the waveform applied thereto from the source of deflection current at a vertical scan frequency to provide asymmetric top-bottom pincushion correction.

Assymetric top-bottom pincushion correction circuit

A protection circuit for a television receiver which disables the television receiver by disabling the horizontal deflection circuit in response to fault conditions is shown. The protection circuit detects excessive current drain by a low voltage supply, excessive current drain by a high voltage supply, and excessive high voltage. In response to any one of these fault conditions, the horizontal deflection circuit is disabled.
