It seems to be a bad LCD panel. Does the image change when you apply pressure on the sides of the LCD panel ? You may try first to replace the LVDS (video cable) or double check if the cable is well connected to the panel (and logic board). Also if you want to be sure that the MacBook logic board is not faulty connect the computer to an external monitor and if the video is normal then the logic board should be OK.
