Hi, my Sinbad pinball is not working. It seems like it should be something simple. When it starts up, all of the lights come on and everything acts like it is working. I can give credits by pushing the lever...and then when I push the start button it makes the sound like it does when it starts, but nothing happens. No flippers, no ball, no reset of targets, nothing...and the credit doesn't go away. If I restart, the credit goes away. Any ideas? I have family in and we would really like to play. Thanks in advance!
