Game powers on but does not boot, appears to be stuck. But before this I had a tech over because it would stop the game and reboot every time you hit all three flipper buttons at the same time. But then today after he worked on it all the lights were on, the dot matrix (new) was not working at all, and now I'm stumped and so is he. New coils were put in it as well. It was still resetting when all three flippers were engaged before this newest freeze up....says he's going to go back to the drawing board. I'm thinking its a power issue at this point, but I'm not techie at all. Luckily this is being taken care of money-wise by an arcade in town who I traded 5 arcade machines with for this machine. Frustrated as hell. Anything you pros out there can think of that I can pass on? I appreciate you reading this. Thank you
