MacBook suddenly has inverted/flickering vertical strip on the screen
I have an aluminum 13' MacBook (A1278) which all of a sudden developed a 1.5' wide vertical inverted, flickering, and interlaced strip running uniformly down the screen. There wasn't any associated drop or other damage to the computer that preceded this. Of note, the left edge of the strip starts exactly at the midline of the screen and extends 3.5 cm to the right -> I'm hoping this might indicate it's a loose cable responsible for carrying the signal to that specific real estate of the screen.
Oddly enough, for the first few hours it would go away if I restarted the computer, but would reappear if I adjusted the tilt of the screen. Now restarting, jostling, shaking, etc has no effect.
Any ideas? I suppose I'll do a little exploratory surgery today and see if I can re-seat any ribbons/cables that go to the screen....I'm hoping I don't have to replace the whole thing. Any tips would be incredibly appreciated....I'm in the middle of exams, and this is not making studying very easy!
