Hello! I have a Gottlieb Joker Poker machine that stopped functioning today and I don't know why. All the sound has stopped working and the flipper buttons won't work. The drop down targets don't pop back up after they've all been knocked down (I knocked them down manually with the glass off). Most of the time when turning on the machine, it was necessary to turn it off and back on before it would properly boot and allow me to start a game. I'm not sure if this is related or not (likely not because I've been using the machine this way for over 10 years). Any advice you can give me is much appreciated! Thanks in advance!
