The inline drop targets on my Fathom are giving me problems and I’m not sure where to begin trying to fix them. I have a new Altech MPU board and I have rebuilt all the connectors on the MPU.
At the start of each ball the game has no problem resetting the drop targets but sometimes fails to drop them down again as part of the cycle before ball launch.
Sometimes it will drop all but one of the top drops and none of the lower green drops.
Sometimes dropping the alternate colored drops on the left hand side will reset the upper inline drops instead of dropping one. Sometimes the left bank of alternating drops will kick out a locked ball in the upper saucer instead of dropping a drop target.
Sometimes the game will function flawlessly for hours. Sometimes it will be a non-stop train wreck.
It’s got issues for sure. Any ideas what to check?
