MacBook Air 2013 13” screen problem

Have any of you encountered the same issue before as mine? Note the edge of the About window overlapping the finder. There’s a strong shader produced. I’ve plugged into external display and it worked fine.
Any solutions to this problem?

Was the MacBook dropped or exposed to liquids?

I would check the internal cable connection and might have to replace the cable to monitor.
That’s where I would start.

If it is the LVDS cable itself, it isn't an easy DIY project based on what I have seen and read.
