My camera won't turn on.

My camera won't turn on but it'll let me view all my pictures just fine. I think their might be a problem with the shutter because it sticks out a bit. When I try to turn my camera on it'll show the FujiFilm Welcome Screen and then just go to a black screen. If there is anyone who knows how to fix this without taking it to get fixed professionally please tell me, i would be very grateful of that! If not, and you know where they can fix it (other then sending it back to the company) please inform me! Thanksss(:
