Backlight working but no image
Good day, my MacBook Pro has a very weird problem when it boots the screen lit up but no image when I connect it to a external monitor it works fine.. one day I power it down and close the lid plug in the external monitor plug in the power cord the Mac turn on I left it there in chrome shell mode for and extended amount of hour when I return I lift the lid, the screen was working fine on then if I close the lid it goes by back to square 1 does anybody knows what’s happening?
