Having the same mac where display is perfectly fine for 2-5 minutes after user login and then it starts flickering and after continuing this way for 30sec-1 min it goes dark.
capslock can be still toggled. Some kind of vertical lines appear(in different patterns each time) before going dark.

Is this a screen issue/flexgate issue or logic board issue? Dont have a spare screen to test.

Posted this here just to get confirmation whether its screen issue as customer dont want to pay for screen replacement.

Anyone knows?

PSisplay fine on external monitor.

This is only a replacement of the LCD. Even replacing the T-con with cables did not change the situation.
