Hey everyone. Hoping for some advice here. I picked up 2 poker machines ( pictured), that weren't working. They both had no power cords, so I took a chance at $100 each. They both have very clean 3902 boards, both have no bill validators, and both have coin simulators. I found some power cords I had , and powered them up. Both work 100%. Touch screen works. Games played. They even had credits on them. The coin simulators on both work fine. .and are set at $25 per press.
I noticed that the button for the coin simulator was added on, and the original service button is still there, but it's connected under the button panel. (See pics). Unusual. The button lights aren't on. Both machines. The buttons do work on both machines. .just not lit. Nor is "machine accepts tickets" lights . I do have other igames and swapped out the i/o cards, but nothing. (Meaning I put in known working i/o cards. .but no change)
What else should I be looking for??
