PROBLEM TO BE SOLVED: To provide an inspection method for a circuit board for preventing an advance a flyback transformer mounted on the circuit board from producing a high voltage in an inspection process in a factory production line. SOLUTION: Circuit components related to a television function and a video function such as a video IC 21, a microcomputer 22, a tuner circuit 25, a television IC 26, a flyback transformer FBT 27, and a power supply circuit 28 are mounted on one board 11, an opening 12 is provided onto the board 11, and a signal wire 13 for outputting a horizontal drive signal from the television IC 26 to the FBT 27 and an earth wire 14 are placed in parallel in a way of bridging over the opening 12. Then in the inspection process, an alligator clip short-circuits both the wires 13, 14 placed in parallel on the opening 12. COPYRIGHT: (C)2003,JPO
