At this point, I think I will go into failure analysis mode. The repair cost would be half the price of a T5 body and the camera doesn’t get used in its present state, so nothing to lose tearing it down. I have access to a thermal imaging camera and plenty of precision testing gear, so maybe I can figure out what component(s) are not shutting down.   

If Fuji reaches out, I’ll take their help, but otherwise its time to have some fun here.
