I have a Sinbad Solid State pinball. I am having 2 problems. One I have had since I got it is, All of the targets don't score so you can never get more than double bonus. After I bought it they all worked for one night and then no more. This also keeps you from getting extra ball, special, etc.

My second problem is that when you use the right flipper it sticks in the up position. When you turn it off it goes down and will stay that way until you turn it on and flip again.

As a side note I was reading something about a grounding setup that can be put on these Gottlieb System 1 machines that helps. I couldn't find an example though.

Thanks for the help.
