Hi all. MacBook Air 2020 M1. When connected to an external screen, there are no display issues so don’t think this is a mainboard issue, but an issue with the screen itself. Is my thinking correct or could it be something else? Thanks Update (06/12/2022)
Sorry I thought I Posted the video earlier. It’s flickers, freezes and then flickers again. It’s useable
Your system is likely still covered under warranty! You have two years in some countries! As long as there is no physical damage and you didn’t get the system wet it should be a free repair. As to what it likely is… At any time do you see any image on the internal display? If you place a flashlight on the screen at a sharp angle do you see a faint image on the screen? And lastly did you place something heavy on the system or bang it?

It’s definitely the screen, not the logic board. The graphics look fine and the artifact looks analog in nature. Everything from the board to the display is digital, so the faulty analog part is mostly inside the screen. Don’t replace the screen by yourself just yet. With new Apple machines, if you touch anything, chances are that they will use the excuse to refuse warranty. Also encrypted stuff like True Tone won’t work if you replace the screen yourself. Check if the warranty is still present.
