PURPOSE:To secure an accurate correction for the distortion of the screen with use of the leakage transformer to which the special winding is applied and by controlling the phase control circuit via the output of the detector circuit which detects the fluctuation amount of the high output voltage. CONSTITUTION:The following component units are provided: horizontal output circuit 2 to supply the oscillation output of horizontal oscillator circuit 1; comparator 25 to supply the output of circuit 1 via phase control circuit 35; horizontal deflecting coil 3 connected to circit 2; and leakage transformer 30. Comparator 25 is connected to first coil L1 mounted to transformer 30, and detector circuit 38 which detects the voltage fluctuation amount of high voltage HV is connected to second coil L2 which is adjacent to coil L1. Furthermore, circuit 2 and pincushion distortion corrector circuit 15 are connected to third coil L3 mounted to transformer 30, with connection of power source 17 via circuit 15. In such connection, circuit 35 can be controlled by the output of circuit 38. |
