I have a bally special force. The commas in the displays that dived the scores into the thousands and millions keep looking like mini electrical charges coming out of them. it happens on any of the 4 displays and most of the time all the commas at the same time. never happens to the number. Don't know what this issue is called so it's hard to look it up. I've included pictures I hope they help.20151207_162924.jpg20151207_162952.jpg20151207_162958.jpg

It was working fine for the last month or 2 just started in the middle of a game Saturday.

Thanks Chris I'll check the voltages on the weekend. Appreciate the help.

can't find the connector your talking about

Checked it today was reading 189. As i was checking it though i bumped some of the connectors and noticed the screws holding the power supply board were loose. Then the game stop registering the ball when it went in the drain and wouldn't start a new game.
I tightened the screws on the board and reseated all the connectors now everything is working fine and the display isnt acting up anymore. If it starts acting up again ill post here.

Thanks again chris
