PROBLEM TO BE SOLVED: To prevent a crosstalk pulse, which is induced on a convergence coil by a crosstalk field from a horizontal deflecting coil, from being inputted to a convergence output amplifier. SOLUTION: Concerning the convergence output circuit, an inputted convergence control voltage is inverted, amplified by a convergence output amplifier 10 and supplied to a convergence coil 8 installed on a deflecting yoke 6 and a convergence field is generated. In this case, the circuit is provided with a crosstalk cancel coil 1A installed adjacently to the convergence coil 8 so as to generate a crosstalk cancel pulse (the inverted pulse of the crosstalk pulse) on a node E with the crosstalk field and resistors R1 and R2 for adding the crosstalk cancel pulse to a node C so that the peak value thereof can be equal to that of a crosstalk pulse added through a resistor R3 to the node C. |
