Everything was normal until exactly half of the screen started looking darker. Then, vertical lines started appearing on exactly half of the screen. When I plug it into an external monitor, everything looks fine on the second display (TV in this case).
I’m thinking of replacing the '''LCD LVDS Cable''' to see if that fixes it.
I have a very similar issue as well…
