I have a couple of year old PS3 SF 103 FP45. I'm hoping I don't have to find the box to get the number but I can if needed, it was a preorder. Anyway it's been working great and then one day recently nothing, no lights, sound, movement. DCS can't find it, factory and feature resets therefore don't work. Will not run conventional.
Took off shell, have AC voltage to both pickups and the PCB. Good ground to PCB as well. No obvious burning smell or dark areas on PCB. Motors and gears turn freely.
Thoughts?
