About a year ago purchased a hardly used 2015 Super Chexx Home Edition with non split base to go into gameroom. Long story short moved to bigger house that I had to split the base to get into my new house basement. Game went back together however every time I hit the boo button (either one) it triggers the eject solenoid as well as BOOOO sounds. I know this isn't right....read somewhere else that it may be the grounds are touching. I will say this I did wing nut all the grounds together on one of the posts holding the circuit board to base....might that be it. Game plays perfect otherwise.
