Guys, i have another board to fix.
The client just drop. No water or something like that.
External monitor works perfect and the screen looks great (no crack or something)

What u guys think it is?

First go complain at Apple if this thing is <2 years old. They will fix it.
After that fails you try a known good LCD first, make sure it is a 2014 model assembly!
