Screen goes blank after a few seconds/minutes
My son's Macbook Air is having some issues with the display. When he turns it on, the image is showing and he's able to login, but after a few seconds, sometimes minutes, a vertical line appears and the screen goes blank.
If connects to an external display, it works fine and there it doesn't show any vertical line.
I already tried resetting SMC, PRAM and NVRAM but it didn't solve the issue.
Does anyone faced the same or have any idea about what might be causing this issue?
