Hi. I have an Asus U56E. When I power it on, the LCD displays vertical and horizontal lines, rendering the laptop useless. I have plugged it into an external monitor and have ruled out motherboard failure since the external monitor displays fine. If I position the screen correctly, I can get the LCD to display everything correctly, but in black and white. The only things I could think of being the problem are the LCD connector or the LCD itself. Any suggestions?
