Well, this kinda sucks but here it is.
Everything was working as expected until I moved the game into the lineup. When I powered it up there, the display did not come on and I found that F3 was blowing on the PS board.
I decided to remove the display board and inspect the display units and found that a mounting screw (a something screw) had fallen into the area between the displays and the display PCB, assuming it was causing a short resulting in the fuse blowing.
I pulled it out and reconnected everything, the fuse is still blowing. Where should I go from here?
