Hello everyone. Im new to the arcade scene and just picked up this carnevil under false pretense of it working. The game itself boots up and works fine. The picture was a bit fuzzy and color was off, so we fumbled with the pots? and got it looking decent. My problem is with the guns. The fella I got it from says he replaced both guns and boards in the guns, and that they just needed to be calibrated. The boards in the guns look to be new. The dates on the stickers say 2011, and the "old" boards that were taken out say 2009. When in the calibration menu's, the trigger and pump action will register, but the guns say off screen. I have a total of 5 gun boards, none of which fix the problem when installed into either gun. There are 3 leds on the board that the guns plug into, is this called the I/O board? The green and yellow are steady, but the red is flashing. Here are a few pics of the machine. Any help would be greatly appreciated as the wife isnt happy about a non working machine in my theater room lol.
