[iBook] dead LCD? Try dead ibook!

[Wegener Media]

Sounds to me as if your board has a blown power supply circuit in it..

Try reseting the Power Manager (button on left side by headphone 
jack), then try it again..Also, try removing the keyboard--sometimes 
a dead kbd will cause this..

  If this doesn't work, it's the logic board..
