Replace the input IC
If you are sure that both the switch and the connections are
good to the board, its possible that the input IC that controls
the input of the sensor may be corrupt. Player # 1 Input IC is
U08. Player # 2 Input IC is U09. Since U10, U11, & U12 are not
used in this game, you may try and swap one of these with the
IC believed to be faulty and then test again. If this fixes the
problem - BE SURE TO MARK THE DEFECTIVE IC SO THAT YOU
DO NOT USE IT AGAIN IN THE FUTURE!
