My TZ started having an issue where it resets mid-play. I can consistently get this to occur by simply shooting the ball such that it ejects out the slot machine. Immediately upon ejecting the ball, the machine will reset.
Any help on this one would be appreciated.
Managed to get a consistent failure each time with a "check switch F3 & F7". Reseated J101 and the power issue went away.
Of course it was followed by "Clock is Broken". Disassembled clock and realigned the hands.
Back to playing pinball again.
