PURPOSE:To improve the efficiency of the adjustment of the entire television receiver by controlling a focus variable resistor and a screen variable resistor with an electronic adjustment means employing a low voltage. CONSTITUTION:Voltage division is attained by employing resistors 3d11, 3d12, 3d21, 3d22 in a flyback transformer 3. A focus voltage and a screen voltage are extracted accordingly based on an input voltage applied to control elements 3k1, 3k2. |
