Fuji XPro-1 Problem
 

Troubleshooting my daughter's Fuji XPro-1 camera. When switched "on", LCD turns on with gray screen, otherwise wholly unresponsive. Removing/replacing battery, trying w/ and w/out memory card, lens makes no difference. Tested battery, reads 7.1 v, spec is 7.5 v. You think this voltage is low enough that the battery is the culprit? Should I order a new battery?

That'd sure be the place I'd start.
Isn't it a rechargeable battery?

The fella that runs it runs the Sony forum I'm on and it's a pretty nice group. They'd probably know the answer.

I had problems with my fujifilm x100. The aperture blades were stuck open. It was a design defect and they covered the repair. I suggest you check the online forums/google.
