I have MacBook Pro 2017 with touch bar (retina) A1706
And it suddenly shows vertical and horizontal lines.
If I connect external display, external display doesn't show any lines.
I already reset the Rams, however it didnt' fix.
I think it might display issue, so I might change to new one.
Please let me know what to do.
My warranty is already finished.
thanks.
