Television receiver protection circuit

In a television receiver having an image display device, a horizontal deflection winding associated therewith, a horizontal delfection circuit connected to said winding, an output transformer connected to said deflection circuit, a low voltage supply including a first winding of said output transformer, and a high voltage supply including a second winding of said output transformer, an improved protection circuit comprising a switching means connected to said horizontal deflection circuit for disabling said horizontal deflection circuit in response to fault conditions and plural sensing means including a first sensing means connected to said low voltage supply and to said switching means for providing a disablement signal to said switching means in response to current flow through said low voltage supply in excess of a predetermined magnitude wherein said improvement comprises:

• a second sensing means connected to said high voltage supply and to said switching means for providing a disablement signal to said switching means in response to current flow through said high voltage supply in excess of a predetermined magnitude;
• and
• a third sensing means connected to said switching means and including a third winding of said output transformer for providing a disablement signal to said switching means in response to voltage pulses across said third winding in excess of a predetermined magnitude.
