Abstract: PURPOSE:To completely eliminate spot burning of a CRT by providing a CRT drive circuit with a spot killer circuit and detecting the +B voltage change at the time of switching of a power switch from the turning-on state to the turning-off state and quickly cutting off the CRT cathode to extinguish a beam. CONSTITUTION:When the power switch is switched from the turning-on state to the turning-off state, the fall of the +B voltage is detected to turn on a transistor TR Tr4, and the electric charge stored in an electrolytic capacitor C1 flows to the base of a TR Tr5 to turn on the TR Tr5, and TRs Tr1, Tr2, and Tr3 for CRT drive are cut off. At this time, the electric charge stored in a capacitor C3 is not discharged by a diode D1 to keep the cut-off state, and resistances R2 and R3 of a bias circuit 1 are kept connected to the anode of the diode D1. Thus, the rise of the +B voltage is differentiated by a capacitor C2 and a resistance R1 at the time of switching of the power switch from the turning-off state to the turning-on state, and it is applied to the base of the TR Tr5 to turn on this TR, and TRs Tr1, Tr2, and Tr3 are cut off.
