PROBLEM TO BE SOLVED: To perform proper correction without using plural correction coils or its switching circuit network for a correction circuit for correcting horizontal linearity concerning various kinds of horizontal synchronizing signals. SOLUTION: A correction coil Lx is serially connected to a horizontal deflection coil Lh connected to a horizontal deflection circuit composed of a transistor Q1, diode D1 and resonant capacitor C1. Besides, a resistor circuit network Rx is parallelly connected to the correction coil Lx, and a deflecting current flowing through the horizontal deflection coil Lh is varied by this resistor circuit network Rx. Even when the releasing state of current is generated inside the resistor circuit network in the case of switching the resistance value of a resistor circuit network Rx, because of the existence of a correction coil Lx, no transient phenomenon occurs at the horizontal deflection coil Lh. |
