Answer to: MacBook suddenly has inverted/flickering vertical strip on the screenI had the exact same problem as the writers above. I purchased a new LCD screen from screencountry.com for $107.50 and followed a Youtube video and screen replacement tutorial on this website. It took longer than expected but I managed to replace my LCD screen and everything seems to work fine. I am no professional, just a college student. I followed the directions that didn't take apart the display assembly and the hardest part was connecting the video cable back to the new lcd screen.
