problem with gtb biatch of a thing

[Olivia_jason]

ok weird problem, my machine had a screw that holds the solenoid braket on break, not biggy taped a new screw in, all should be fine and flipper mech all replaced like the 1000 times i have done in the past.
anyways turned machine onto test thing fired up worked a few seconds then the solenoids cut out. hmm checked fuse no problem fuses fine, then went into test mode and all solenoids worked fine, and everything came up good no faults shown.
ok turned machine off, pushed start and the start button added a credit and entered its self into test mode from the start button, lol
ok weird, turned it off again started fine, then went to hit start button and again added another credit when i pushed the start button lol and then pushed it again and it went into test mode from the start button.
WTF is with this??

also the weird part was you could cycle through test mode from start button, that has never happened before
