Screen problem with MacBook pro 13 inch late 2016

When I started up my Macbook this morning, the screen was black.

However, on top there is a tiny stripe of the actual and responsive screen visible and I can even see the tip of my pointer move there.

But there is nothing I can do with it.

When I close the lid and open it again, I see an actual display of a random program, with random windows in it with the pointer frozen. That part is is unresponsive. Also it changes at random when I close and change the lid again. Now and then there are also horizontal stripes popping up.

And all the time there is the tiny stripe of the actual screen which seems to respond to all the keys and pointer. Problem is that, since I can not see the screen properly, I can do nothing with it.

I tried all the tricks mentioned on internet, but nothing helps.

I also cannot find a similar case as mine. There is a lot about a black screen, but nothing similar as what I experience.

Any help?
