You're power supply isn't putting out the voltage it should. look inside the lower cabinet under the table (there's a lever inside the coin door that unlocks the front plate so you can slide the glass out and lift up the table). there should be a silver box towards the back on one side. look on the side of that box for a potentiometer (small silver knob) that adjusts the output voltage. turn it slightly clockwise to increase. if you have a voltmeter, put the black probe in the power supply molex plug (white plug with multicolored wires) in any black wire and the red probe in the red or yellow wires. the red should be 5.2 volts dc and the yellow should be under 13 volts dc. be careful, though. much of the game takes dc voltage, but the flippers take 120 volts ac (just like the outlet).
