PURPOSE:To reduce the power consumption of a vertical deflecting circuit by using the bias current of a transistor TR of a vertical outputs stage as a centering current supplied to a vertical deflecting coil. CONSTITUTION:In the vertical deflecting circuit, a collector bias current base on a base bias voltage set by resistances 23, 24, and 25 is always flowed to the collector of a TR22 which is the vertical output element, and this bias current is used as the centering current of a vertical deflecting coil 26. Thus, the bias current is used as the centering current to prevent the loss of the power consumption in the vertical deflecting circuit.
