Tried the "taped straw fix", alcohol cleaning etc with old optos. Finally installed new transmitter and receiver tonight but no better. Still can't get consistent signal break recognition during game play or test mode. Is alignment this tough to get? Could there be an electronic or wiring component causing this? These optos just refuse to regularly see the ball....or my hand in test mode. Very finicky and inconsistent.
"FLIPPERS, USE THE FLIPPERS" is killing me
