A1466 2017 MacBook Air startup with White/rainbow colored lines?
Hi, I have a model of the MacBook air above that started booting, with chime, and the apple on the back lit, starting as a white screen with rainbow lines to the right of the screen, then it slowly fades to a screen with black on the top and white on the bottom and the colored lines are still faintly there. I was guessing that there was probably an issue with the internal connector from the mainframe basically to the screen itself. I have tried all the alt/shift/control/hard reset options and memory resets with no change in the screen.
Two questions -
- What is the issue, if anyone can pinpoint it (I have video and picture of the issues as well) with how to correct it?
- Is there a way to attach a monitor and bypass the laptop screen without being able to access the homescreen?
Thanks.

To verify what you need to focus in on you'll need to connect your system to an external display to see if the image is good on it.
● If its good then its the internal display
● If it's bad then the logic board has an issue

Hi @wttay515- I have the same thing happening to my MacBook Air (same model). Just wondering if you ever solved what was wrong with it?

@kfno - Did you isolate which needs service as I outlined above?

It was the school I work for computer, so they just replaced it. I’m pretty sure it was the logic board unfortunately.
Nothing happened with the monitor attached
