Cheers Everyone! my macbook has a problem that really worries me a lot. The screen does not work. When I turn on the computer it flashes once and then all black. The white light near the infrared on the right edge of the computer also stops when the screen stops. The computer is working coz I connect it to a LCD and I can work with it. I have the software up to date. The only thing I did recently was that I had a problem with my printer and I had to uninstall it and install it again and then I had to do a thing on disk utility that was repair disk permissions. one day after that the screen stop working. Any ideas if I can solve this? It's really strange because I know the screen works when I turn PC on and then it goes of!
