Answer to "Stage Light Effect on Display Screen"I had exactly the same issue, I replaced the whole LCD screen assembly and it works again. I hope I’ll not have the same problem in the future. If it’s the flex cable that fails it can fails at anytime even if the whole LCD screen assembly has been replaced. It’s not very ecology minded from Apple to force their customer to replace the whole screen assembly when it’s just a flex cable that fails. For a company that communicate about being “green” it’s not very consistent. And that’s really not what I expected from a 2600€ laptop. Anyway, I hope future model will not have the same flaws, and I say that already knowing that the 2018 model have the same design, so it’s not a good news. They have fixed the keyboard flaws years after year, but the screen backlight seems not to concern them. Maybe it’s less visible, maybe it’s not as frequent as the keyboard. Well, I hope so for my screen !
