Screen issues, Back light dims & goes out
I have a 2016 macbook touchbar 13" and one month after the 1 year warranty I noticed this "stage lights" issue. 5 months later the issue is worse now.
Yesterday, I noticed that when I tilt the screen back beyond the 90 degree angle the screen goes black. Then if I move it back to 90 degrees it gets illuminated. But the angles vary a lot. Sometimes it gets illuminated only If I move it back to 60 degrees and sometimes a little more than 90 degrees.
One important thing to mention: when I open the lid until 60 degree there's no stage light issue, the display is clean, with no shadows. The issue starts at 60 degree with the shadows appearing and screen brightness being lowered until it goes black.
It works perfectly with an external monitor. So it must be something with a damaged display cable, right? Can it get worse than it already is, like damaging the logic board or something?
I can't afford an expensive repair (new display) so if I'm safe keeping the lid closed, I'm planning to use it as a desktop.
