Hello everyone! I'm very new to owning a pinball machine. I Purchased a Jurassic Park Machine about a month ago. This is my first machine. Im sure this question has been asked before, but the trex jaws just started to close after the trex is back in the upright position. So it does not pick up the ball anymore. Im just curious if you guys have any idea on where to start to diagnose this issue. Again im new to this so this will be my first repair lol.

Thanks in advance!
