It sounds like the safety timer has tripped. This happens when the hopper does not have enough coins to pay off a jackpot. The safety timer is located behind the hopper in the left lower rear of the cabinet. Your machine should have a flat bar that runs under the hopper to the safety. It should just stick out from under your coin hopper. Push that bar back towards the rear of the machine. That should reset the safety time. You will need to put the coins back into the hopper so it can continue to payoff the 100 coins. If your machine does not have the flat reset bar, then pull out the hopper and push the white button switch. That should start your machine. You might see a red light on next to the push switch, that's normal and will go out once you restore the power by resetting the timer.
