Pink Lines on iPad Pro

I was working on my iPad Pro, and suddenly pink flickering started and eventually froze. Since then, the machine has been unresponsive.

I tried pushing the volume bottom, up and down and the top button, but the screen is frozen with three broad pink lines and one small line at the bottom of the screen.

The computer has not fallen or pressed hard as it is stationed on a desk only with its magic keyboard.

What should be done?
