I got this Macbook Air for repair and I’m still not a 100% sure if this is the LCD problem or logic board problem. Watch here: https://www.youtube.com/watch?v=oym6NBeN… Everything is blurry and it’s like the frames do not refresh and stay there longer. The effect is worse when the display brightness is low (shown in the video) Customer told me there may have been a water damage on the keyboard. External monitor does work normally. What I already tried: I cleaned the motherboard with isopropyl-alcoholreconnected everythingopened the electronics under the display and wiggled with cables (no clear image)re-installed mac os Nothing of the above helped and I’m inclining to think it’s more likely a LCD issue. Can I be more sure before ordering an replacement? Also the two white dots on the screen suggest a mechanical damage? Thanks for any tips.
At this point the logic board looks very clean! I don’t see any signs of damage so I don’t think you have a logic board issue from the bottom side. You might want to double check the other side. I do feel the issues is within the display its self.
