I've used your website to fix 2 iBooks successfully and I am thinking about buying additional ones on ebay for parts and put one together. Can a processor be swapped out or is it included somewhere that can't be replaced? I don't see it as a choice on your repair options. Thanks! And can the light of the monitor screen (if it is dimmer than normal) be replaced as well? Not sure what allows or gives light to the LCD screen. Thanks! Trying to learn more.
