。In a television receiver in which a voltage divider circuit for extracting focus or screen voltage is provided between the stages of a multi-voltage rectifier circuit connected to the high voltage winding of a flyback transformer, a DC low voltage is supplied from the voltage divider circuit. A horizontal hold-down circuit for a television receiver is designed to stop the horizontal output circuit when the low DC voltage rises above a predetermined value.
