I need help. I am rebuilding a TZ and have some really weird stuff happening. I'm so close to being done, but am now ready to pull my hair out! Let me describe what's going on:
-At first, the left ramp switch was triggering more than just that particular switch. It was also triggering lower lock, center lock, and upper lock (as well as one of the trough switches---can't remember which one). Those individual switches all worked fine, but the ramp switch would trigger all of them as well.
-While trying to fix that, I lifted up the playfield and must have pulled on something while doing so because all of a sudden the display went out (only a few vertical lines show now). I also noticed that the game is doing some really weird things now like trying to look for the ball in the auto-fire lane and the slot kickout, and the left jet bumper isn't working. I've looked but can't find anything odd, and can't diagnose really because the display won't work!
-In an effort to fix that, I thought, "hey maybe I just blew one of the switch matrix chips. I know, I'll pop my working Whitewater board in (with the TZ ROM) and see if that fixes it." Well, now that board isn't working either so I've definitely got a blown chip on both of those board, as well as something touching that shouldn't be somewhere.
Any help appreciated!
