Hello all! My uncle dropped off an IGT Reel Slot machine for what he claimed was a problem with the lights. I'm not used to working on slot machines so please forgive my ignorance. I'm used to arcade and Pachinko machines.
So the machine powers on, lights up, and seems to cycle through a series of clicks. The yellow light on the top of the unit is flashing. The boards look clean and the fans run. Dropping a quarter into the slot dumps straight to the pan. Looks like the solenoid behind the coin mech is diverting the quarter.
Any advice on where to start would be appreciated. I haven't been able to find any manuals or schematics for the machine.
Below are some pictures of the insides. Super clean looking machine.
