What's up everyone. I am experiencing some issues with my Indy and would greatly appreciated your collective help/advice.
The Problem:
All of a sudden, while playing a game, the colorDMD went out and balls starting rapid firing out of trough, into the shooter lane, and plunged into play. The coil (not the once that fires the vuk to launch balls into the idol lock, the one before it inside the subway) inside the subway once you hit the center ball lock is also firing every 3-4 seconds. I've checked/tested the F116 fuse and all other fuses for continuity and it's fine, but replaced anyways based on some previous troubleshooting posts. I also checked the wiring for the idol lock opto lights to see if anything looks strange...nada. Also looked at the diode for the lower right POA switch as that comes up in many troubleshooting posts for switch matrix issues but it's not smashed and looks fine. The led status indicator on the 10 opto board is out. I can hear that there are multiple credit dots as I'm sure a row or column in the switch matrix is likely out, but can't see what they are because the dmd is out.
This happened several months ago and the F116 fuse was blown so I replaced it and haven't had an issue since. I'm running a pinsound in addition to the colorDMD and the jackpot light mod, but all of those components have been in the game for several months so nothing was newly added. I recently added an LED under the playfield to light the mode start hole, so perhaps that led touched metal and shorted but it's still working.
This is frustrating and I'd love to get indy back up and running.
Thanks!
