When I try to boot my Macbook A1342 late 2010 model I get a white screen with faint black lines on the screen. I had replaced the LCD and I get the same thing. So I thought it was the video cable, replaced that and I still get the same thing. If I leave the macbook on the black lines get more darker. The whole thing itself boots up just fine cause i can hear the starup noise and if I press the buttons I hear that bump noise you get when you enter a wrong password. I can change the brightness and everything. Any help would be apperciated.
