Olympus OM-D E-M10 front curtain flutters?

Hi everyone,

I got this problem with my EM 10. When the camera is off, the front shutter curtain stays shut (normally it is open). When I turned the camera on, the curtain will flickers for a few times (make some noise) then it stays shut and the camera will shut itself off.

I can't access the LCD menu and cannot take a picture.

Anyone know how i solve this?

It is similar to this problem on youtube -> https://www.youtube.com/watch?v=dhmzvbxO...
