650d Power switcher out of order

[Nils_650d]

My 650d has the Probleme that I stuck in the Video Mode.
If I put the battery in and the power button is off,on or video, she starts always in the video and
on the display stands "the camera was not clearly sthut down skipping module loading"
When i want to change now to the normal mode nothing hapend.

I have deinstalled magic lantern and installed it but nothing happend. I updated the camera software and put all settings to factory settings, too.
In ML I have turn off all mode.
But nothing helps.
