Computer starts (keyboard lit, music plays, caps lock light on), but no screen. I need to open and close 2 - 30 times before the screen will turn on. Once on, the computer works perfectly. I've tried PRAM and safemode reset. Please Help.

    Try this from another forum user:


    1. Shut the computer down by holding the power button for 10 seconds

    2. Restart the computer and press shift at the same time until you see the progress bar start moving

    3. Once you reach the point where your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password, then hit Enter.

    4. After a moment, you should see the spinning beach ball

    5. Your screen should then move on to something along the lines of "Completing OSX Installation" (I can't remember the exact wording). Let it finish. After that it should go to your normal desktop and the issue should be fixed. (If your screen goes pitch black during this process, hit the space bar. I thought it wasn't working, but the screen was just sleeping).

    That just started it up in safe mode and didn't help so;ve the problem with the black screen. Do you think i need to re install my operating system?

    No, I think you need to take it in for service. I think your display has gone.

    I did take it in for service, they said it is a back light problem in the mother board. They said I would need to replace it, but it cost too much. Do you have any other suggestions on what I can do?

    Sorry, no. I suggested you have it repaired. You were informed of the repair needed, but you refuse to have it repaired. There's nothing more to do but put it up on a shelf somewhere until you decide to pay for the repair or buy a new computer.
