Hi all
I had a scoring fault on my QD, in two player mode, that started happening recently, sometimes 3 hundred points was being added to the score of the next player before their ball had been launched. This was intermmitent and would happen to both player one or two. I have no idea why it was 3 hundred points as there is no target etc that scores this value. Anyway after having a poke around, I widened the gap on the "trough" switch and this appears to have fixed problem. Looking at the schematics I assume there is a race between the "ball return" switch and the "trough" switch. Thought I'd mention it here in case someone has similar score problem down the track.
Cheers
Dave
