PURPOSE: To attain almost all change related with vertical deflection by inputting a prescribed program to a microcomputer in a television receiver, and changing the position of the vertical deflection and the constant of a frequency or the like. CONSTITUTION: A microcomputer in a controller 1 of a vertical deflecting circuit 16 has a first stage for inspecting whether or not a bus(BUS1) for control and adjustment is used after initialized. When the BUS1 is used in the first stage, an operation in the state of the BUS1 is executed, a color picture tube(CPT) image inputted from a television camera 14 set in front of a CPT is converted into digital data by an A/D converter 7, and this digital signal is transmitted to an adjusting equipment 6. This digital signal is processed by the adjusting equipment 6, a vertical deflection state is inspected, a value by which a correct state can be obtained is decided, this value is transmitted through the BUS to a controller 1, and the vertical deflection is corrected. This correction operation is repeatedly operated, and the adjustment is ended until an optimal state can be obtained. |
