Visibly blinking screen

[khumarahn]

The screen of my laptop started blinking with a frequency that I can very well see with my eyes. There have been no hardware or software changes for quite some time, and previously the screen used to work OK. I carry the laptop in my backpack when cycling, so there might have been some mechanical stress.

I did not investigate, and may not have time for it in the near future, but maybe somebody else had this problem? Or maybe someone knows what to look at?
