Hey everybody I need some help. My lcd screen won't display anything, but everything else works fine, like the volume and power. When I turn it on I can hear the lock screen opening and the touch screen works to. When I tap my hands in the keyboard area (where the keyboard would be displayed on the screen) I hear the keyboard clicks. It's like everything works except the screen display. I could probably even use it without having to use the display if I memorized where all my apps were. Does anyone know how I can fix this? It's driving me crazy. I checked the logic board and everything is fine under there. Could it be a cut ribbon? Even though I'm positive I didn't mess anything up replacing the touch screen. Or do I need to buy a new lcd or lcd ribbon?
