2020 M1 MacBook Air Screen randomly turns off. Backlight is still on.
I'm hoping someone can point me in the right direction here.
I bought a used 2020 M1 MacBook Air. The machine is in very good condition and everything seems to be fully functional except for this one issue.
Every now & then the screen just randomly turns off. The backlight is still on though & I can even adjust it's brightness. Everything else still continue's to work, YouTube audio keeps on playing, I can adjust the volume & hear mouse clicks etc... Just the image has disappeared.
If I close the lid & open it again, the screen comes back on & is working fine again. Sometimes though I get some horizontal lines on the very top of the screen (about 1cm size) and the image is frozen. If close & open the lid a few times, the display returns back to normal & all is good again. Sometimes I can go days without this happening at all, then suddenly it kicks in & becomes a PIA.
So I'm hoping someone with a more technical background could give me an idea of what the problem sounds like to them.
Is it an actual screen problem (replace the screen)? Perhaps a FlexGate or ribbon cable? Faulty T-CON board or display angle sensor?
Anyone that has a good idea where I should start looking. I don't want to buy another screen only to discover I still have a problem. Any guidance will be appreciated.
Thanks so much.
Is this a good question?
