I need help. In the middle of a game, one of the coils started acting up and seemed to fire on its own. The game screen then went dark. I shut down the game and restarted it. When it started up, the game seemed ok but very quickly into my first plunge, multiple coils started firing. I heard a pop and smelled burning. I turned off the game again quickly. I looked inside the box, and the only thing I saw out of the ordinary was this burnt looking chip on the I/O board (see picture below).
Note that I recently converted the game to the 2.0 lighting system. However, I played multiple games since doing that and everything played well. More recently, I waxed the game, and this was my first game after waxing. Not that waxing would do anything, but I did pull out the playfield a bit to get everywhere.
Any ideas? Is this just bad luck, and my I/O board went? Do I have some other issue that caused the I/O board to go? I'm really bummed out as I just spent all that time on the 2.0 upgrade only to have this happen a week later. Thanks in advance for the help.
