Well, I wouldnt advise doing it yourself. Id take it to an Apple dealer and get the price of the replacement. Then consider whether you actually need the computer to still be mobile. If you dont, you can always run a mirrored second monitor and screw the x amount of money youd spend on reparing it. If you do need mobility, then get it replaced. there are no thrid party iBook LCD replacements that Apple allows (I dont even think they exist period) so your best bet is to just see how much a replacement is.
