    My iBook will not display anything on its screen. Rather, it just remains black. One time, the screen did come on, but then shortly after booting, it flickered a lot and then went black again. A year ago, something similiar happened and when I took it to be serviced (when I had AppleCare), they had to send it away and have a new logic board installed. Now this machine is out of warrenty and and I am not sure what to do, or even if it is the same problem. Any suggestions?? Thanks!:confused:

    Do you have an external monitor with which you can test this iBook?

    If not, try this: when it's turned on (but apparently dark), take it to a location where you have lots of bright light -- e.g. next to a window. Hold it up to the window so that the light is shining against the back of the screen. Can you see stuff going on onscreen -- windows or text or anything, perhaps in the center where the Apple logo cutout is on the back?

    The reason for this is that there are a couple of major possibilities:

    - Your backlight is bad
    - Your logic board is fried again

    Either way, fairly likely this is a hardware issue. :( However, the backlight issue is not so expensive to fix, typically.
