Blew the flasher fuse in my freddy pinball while back. Now freddys head flashers and lightbox eye are not flashing. Leds work but dont flash. Changed out q21 sol 20 mosfet because it looked burned, had low mm reading and had read other forums of similar issues. Mosfet not issue still have same issue. Is there something else on that trace that might be causing issue? Please help.

When mosfet burns, it also could came from a bad connection at ground wires connector on top left of the tranformator. You better did the ground update as it is preconized on http://www.pinrepair.com/sys3/

If already done you might check any solders link to the ground wire that activate Q21 Sol20 (got nothing there on Stargate schematic)
