lcd – How can I repair an Olympus OM-D E-M5 with a black screen, take a picture and turn it off?

Suddenly, the LCD screen of my camera does not work when it is on but I can still take a picture. But after a click the camera turns off automatically.

The previous times when I use it, I realize that when shooting with the shutter low, the camera jams from time to time, but usually an on / off resolves it.

Now my camera is unusable. How can i fix this?
