A Fliptronics flipper does not fire when its button is pressed, and the coil, driver transistor and wiring are fine.
Fliptronics flipper does not work: test the flipper opto board
Cause: A failed U-shaped opto on the flipper opto board. Each board has two optos even on two-flipper games.
Checks
- Check the opto with an infrared sensor card.
- Or exchange the two flipper opto boards between sides; a fault that follows the board is on the board.
- Both boards must be plugged in for either to work: opto power runs from the backbox through the left board to the right one, and ground runs through the right board to the left one.
Fix
- Replace the failed opto.
- On a two-flipper game you can move the good unused opto into the used position, but see the note on switch errors.
