The screen on my macbook (07 White 13" Macbook) is only displaying the top half of the screen.The bottom half is filled with colored vertical lines.On occasion it will clear up partially but mainly stays this way. I have reset the smc and pram. I have also disassebled and reseated the connection on the back of the lcd screen only.I have not reseated the connection wher it goes inside the computer body itself.
