Let me preface this by saying I'm a newbie - just learn about EM maintenance & repair, so please dumb down any responses. (I do have the schematic for this game)
I bought this game a couple months ago - my first. It's in pretty decent shape, no major issues. Except for one: double bonus. I noticed the machine was only giving me 1.5 times the bonus amount. So if I have bonus maxed at 15,000 and have double bonus, it only gives me 22,000 points, rather than 30,000. If I have 10,000 bonus, double bonus gives me 15,000 points rather than 20,000.
When I noticed this, I started paying attention to how it was counting down bonus. And it chimed: ding..ding-ding...ding...ding-ding...ding...ding-ding... all the way down. In other words, it was giving me double bonus every other time as it counted down. Then, the other night, on one random ball, I noticed a different sound: ding-ding...ding-ding...ding-ding...ding-ding...ding-ding... all the way down until it got to 1,000 and then it gave me a single ding (and a single 1,000). The next ball, it was back to giving me double bonus every other time as it counted down (or 1.5x bonus).
Anyone ever have this issue before? Suggested solutions?
