Macbook Air's display: weird shadows and black screen.
Hello, recently my early 2014 MacBook Air (A1466) has been showing these weird shadows on the bottom of the screen, alternating with constant flickering, a big shadow only on one side of the screen then on the other, and oftentimes the screen goes black for a few seconds, then comes back. This problem seems to happen without explanation and it doesn't matter if I tilt the screen to a certain angle.
I've uploaded a video showing this issue: https://youtu.be/j968h5kqVoQ
What's wrong? Is the machine just too old? What's the fix?
Best regards.
