Answer to: MacBook suddenly has inverted/flickering vertical strip on the screenI just had the same problem (the strip was not at that exact place, but apart from that everything was exactly the same). I brought the MacBook to a Genius Bar, in an Apple Store. The guy sent it to an external company they work with, where they have a flat rate for repairs. They changed the LCD display for $280+tax, which is not too expensive. It took three days.
