Have an Embryon that worked fine until about an hour ago. Played every ball etc. Now, after I rebuilt the power supply and replaced the two large caps on the solenoid driver, the game will not send a ball into the shooter lane. It will also fire the upper outhole several times at random upon first start up. If you start a game and hit the flippers, the outhole will also occasionally fire. I still do not have any sound either. Thoughts?
