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?
