Answer to: MacBook suddenly has inverted/flickering vertical strip on the screenHey guys, i have a macbook late 2008 and had this issue. i tried pushing everywhere on the screen and tried the figure out what the problem was. when i pressed on the flickery part the flicker went away but it didn't last long. I tried another technique which was applying torsion on the screen by holding it with two hands(one hand on one top corner and the other hand on the other top corner). Push one hand while you are pulling one. You kind of have to twist the screen. Twist it as much as it won't break. don't be gentle but don't be harsh too something between them.
