Behinderungen » Radio working but no display?

Hi,

I had to give someone a jump with my car today, but I noticed later when I went to drive again that my display wasn't working. I had sound, and could move the radio presets like normal but the screen is completely blank. I have no idea if it was related to giving a jump or not but that's the only different thing that happened today with the car.
Anyone else had this?

Please help.

I didn't find the right solution from the Internet.
