Hi all - I have just bought an old pinball machine - Cosmic Princess. It is complete but it won't start a new game. I insert coins and the credit comes up and I start the game but the ball doesn't pop out. Flippers work and everything, and I can hand-start the game but when the ball goes to the bottom, the plastic targets in a row buzz and some stay up but it keeps going through the reset cycle. Any suggestions welcomed. Thanks in advance. Rossco
