I have a Upright Discs of Tron I purchased non-working. I was able to get it to come up by swapping out the MCR power supply. Now it can play, but has no sound or spinner control. I ran the test function, and it showed no errors. During the input test, the spinner would not show up. The spinner did show up when you pulled up on it or pushed down on it but not on any rotational movement. The sound test did not produce any audio results. As part of troubleshooting, I put the DOT board stack into my Tron and it did the same thing. No sound or spinner movement. So I am guesing this is not a cabinet issue unless the Tron and DOT are not that easily interchangable. I did change out the old original ribbon cables to the new computer type. It still does the same thing - no audio or spinner. I had originally thought it was a connection issue since I had a similiar issue with my Tron (Tron could not move right & partial spinner control) I found two loose wire connectors. But since it follows the boardset, I am guessing it is something else.
I have included pics of the boardset in the Upright Discs of Tron. Hopefully someone has seen this issue before or knows what I need to check or causes this.
