Hi! I have a MacBook Air (Early 2015). When I turned it on, when you can see the apple logo, about 2 inches of the right side of my screen turned grey from top to bottom. I have noticed, and by having done a dead pixels test, some pixels look dark blue/black when part of the right screen is grey or dark green or sometimes yellow. But otherwise, it looks fine. I would like to know what’s the problem (perhaps stuck pixels? or a connector?) and how to fix it? How the problem first appeared:
It’s already better:
The chroma effect in the bottom right corner is a T-CON failure which is within the display lid at the bottom edge. You likely used a spray cleaner which dripped down wetting the logic. Hopefully you don’t have anything brewing hidden behind the bezel. From now on spray the micro cloth and then wipe the screen or even the body so you don’t get any cleaner deeper inside.
