Hi, I put a DVD inside my macbook pro a few days ago and the screen just went off. When I restarted it, I can see the apple logo light up and the keyboard backlight on, but the screen is just black. But external display does not have any problems. I did a restore of my macbook pro and reinstalled snow leopard. The black screen is still there! There seems to be no problem with the external display though.. Can someone please help me solve the black screen problem? I took it to the apple customer support and they slapped an $800 quotation on me! I dont want to spend so much money..might as well buy a new one! Please help me with the problem! thankss!
