I have a WD Premium that is acting strangely. When pressing the start button to start a new game, the prison targets start firing without even plunging the ball, PRISON spells out on its own after about 15 seconds. It seems that if I reseat the ribbon cable that connects the main two circuit boards in the backbox, the problem goes away every 20 games or so, then the problem starts all over again.
Ive replaced the ribbon cable once already and that did nothing to solve the problem. It seems that the sensor in front of the prison house is clean with out any obstructions breaking the beam. No technician alerts display when I go into the system menu.
I have absolutely no idea how to fix this problem, please help!
