Abstract
PURPOSE: To make easy cut off adjustment, by drawing out the terminals from the vertical driving circuit and the video amplifying circuit respectively, and shortening them.
CONSTITUTION: When the terminals T1 and T2 are shortened for cut off adjustment, the vertical driving transistor Tr4 is conductive, and the voltage at the junction point P is almost at ground level. Thus, Tr2 constituting the differential amplifier of the video amplifying circuit 2 is non-conductive, and the gain of the video signal is zero, and the video signal to the video output circuits 100 to 300 is cut off. On the other hand, the conduction of Tr4 turns on Tr61 of the vertical output circuit 600 and the collector output is almost a given level close to zero. Accordingly, no current flows to the deflection coil 70 and the vertical oscillation is stopped.
