    PROBLEM:
    I start it up my Powerbook and I get screen activity for about 1 second (see videos) and then it goes dim. You can still (barely) see the display.

    STEPS TAKEN:
    • Connected external monitor, pressed F7
    • Repairing disk from PowerMac G5 failed in Target Disk mode.
    • Reset PRAM.
    • Tried starting up from disk.

    The screen fickers and goes to almost nothing... What is wrong with my PB?
