。 A vertical output circuit applies a sawtooth vertical output voltage to one end of a vertical deflection coil, and is triggered by a vertical oscillation pulse, integrates the output voltage of the vertical output circuit, and the integrated value exceeds a preset reference value. up to at least the vertical retrace period,
Furthermore, during the vertical scanning period, by supplying the mirror integral output generated by charging the feedback capacitor connected to the other end of the vertical deflection coil to the vertical output circuit, a sawtooth waveform with a vertical scanning period is generated. The output bias of the vertical output circuit is adjusted by rectifying and smoothing the voltage taken out from the wave generating circuit and the other end of the vertical deflection coil, returning it to the sawtooth wave generating circuit, and adding it to the integral value. Vertical deflection circuit consisting of a stabilized output bias stabilization circuit.
