The vertical output pump-up circuit for varying a vertical output voltage according to the flyback time and scanning time of the vertical output circuit to reduce the consumption power, includes a transistor (Q1) connected to a vertical output circuit (1) through a resistor (R2); a transistor (Q2) connected to the circuit (1) through a resistor (R3); a power terminal (Vcc) connected to a base of the transistor and a collector of the transistors (Q3)(Q5)(Q7); and a diode (D1) connected between the base and emitter of the transistor (Q1). The vertical output circuit (1) outputs a high voltage for flyback time (T1) and a low voltage for scanning time (T2).
