Screen Black after flickering colours
Have a MacBook Air, we had reset and seemed to be working fine.
Then upgraded to Big Sur and screen started flickering lines across, this kept speeding up when the macbook was on and eventually the full screen went black.
Now the macbook is coming on but only with a black screen I’ve tried downgrading the laptop to Catalina (Not sure on original version). but same issue as screen is still black, plugged into external monitor and can see the operating system working.
Ocassionally screen flashes white for like half a second. Any help would be great.

@bobooc - Did you try connecting an external display yet?

Yes, I've had the machine working through the external display. After the screen stopped, but seems weird for the screen to be working perfectly fine until I updated to Big Sur.
