PURPOSE:To determine the phase and pulse width of a drive voltage easily by connecting an output of two-input OR circuit to an input of a horizontal drive circuit and inputting a horizontal oscillation output voltage and a horizontal output pulse voltage to the OR circuit. CONSTITUTION:A horizontal drive circuit has a drive transistor (TR) 2 and a drive transformer 3, and a horizontal output TR5, a horizontal deflection coil 9, and a flyback transformer 10 are connected to the secondary side of a drive transformer 3. A 2-input OR circuit 1 is connected to the base of the TR2. A horizontal oscillation output voltage is inputted to one input of the OR circuit 1 and a horizontal output pulse voltage from the flyback transformer 10 is inputted to the other input. |
