PURPOSE:To dispense with a switching circuit, etc., by changing a source voltage by a voltage control part at every MUSE system or NTSC system. CONSTITUTION:The appropriate value of a supply source voltage is set at every MUSE system and NTSC system, or every horizontal deflection circuit 10 and high voltage generation circuit 2. Furthermore, voltages different at every system and circuit from the voltage control part 4 which inputs a DC voltage Vcc, right and left pin-cushion distortion correction voltage, and a system switching signal are supplied to the high voltage generation circuit 2 and the horizontal deflection circuit 10, and the required high voltage and horizontal defecting current can be obtained. Thereby, it is possible to dispense with the switching circuit and a coil. |
