I have an iBook G4 (the 14 inch) with some screen issues, but all of the internal components work well. Looking around eBay I can find iBooks with working screens but non-working internal components. Is there any way I could buy one of those and then switch the parts to make a functioning iBook? I have a small amount of technical knowledge and no tools other than standard screwdrivers. Is this possible for me to do? Know of any tutorials, etc.?
