I shopped out a Bally Game show pin a long time ago and it has been sitting for a while now because when it was re-assembled, it had an issue with 2 flashers being stuck on. I have come back to this and want to get it working again. Any idea what would cause this? Maybe as simple as an incorrectly plugged in connector?
The noise after the adjust failure is cleared is the left slingshot firing. I believe that is unrelated (but still not sure why it did that)
Here is a short video of the issue. The machine will play after boot up but I don't want to leave it on like it is.
