My Macbook Pro 2017 with Touch Bar has one vertical line about 5cm wide that changes colours when opening/closing the lid. Otherwise, both vertical and horizontal lines appear all over the screen, at times making the entire screen unusable depending on the angle of the display. Can anyone tell what is causing this and how to repair it?
Ouch! Somewhere you either banged or dropped something of weight onto your systems lid which damaged the LCD. There is nothing you can do to fix this, you’ll need to replace the entire display assembly following this guide MacBook Pro 13" Touch Bar Late 2016 Display Assembly Replacement and here’s the needed part MacBook Pro 13" Retina (Late 2016-2017) Display Assembly
