I replaced LCD, it works but the screen goes black on login.
My LCD got cracked on my 2007 Macbook Pro 15" laptop, so I replaced the LCD screen with a new one. Everything seemed to be looking good, and when I turned it on the new screen worked! However, as soon as it got to the login screen, the screen went black :( .. any ideas? If I restart it, it does the same thing each time. Also, if I plug in an external DVI display, I can see my computer, but it doesn't even recognize my display when I try to look for it in Displays in System Prefs.
Any ideas? Thanks!
