Problem:

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.

Answer:

Apple appears to have a run of displays failing in the new 2016/17 models!

Sadly, the cable between the backlight within the display and the connection to the logic board is the issue here. The flexing of the display (opening & closing the lid) fatigues the wires within the ribbon cable. The complete lid needs to be swapped out.

If a fix is not in order, a wild suggestion (I've done this) is to use an external display and keyboard/mouse and call it a mac mini. Definitely not portable, but you can get a large monitor for cheap (a la thrift store). Feel free to ignore this suggestion.
