I have the first year Macbook unibody aluminum. So in the last couple weeks the screen has been flickering, i would get portions of the screen that would flicker the brightness or kind of shake the picture. i could fix this by just moving the screen a bit and if i hit the sweet spot or sometimes it would just go away. now it has gotten to the point the screen will freeze and then slowly fade to white untill i move the screen then it will be fine for about 5 minutes till it does it again. I dont think its a bad lcd, but it could be. My guess would be a bad connection from the video card to the lcd, wanted some advice and to see if its a diy. Its also out of warranty, and no applecare.
