Screen freezes but external works after dropped

Sadly I dropped my A1707 and it landed flat on it’s “feet”. Now the screen and cursor freezes after 10 sec when starting the computer. But, when connecting to my external screens, everything works fine. If disconnecting, and open lid, it freezes after 10 sec, the menu bar changes and gets half transparent, I can se a bit of the cursor at the top, moving horizontally when using trackpad, bud not vertical.

Is it the screen that’s gone bad, or the graphic card or?
