"iBook G4 Display totally Blank"に関する回答I have an iBook G4 that works fine with an external but shows grey screen on the internal. As I rebuild these machines part time, I tried a total of (4) other internal displays(inventory) with no joy. I read once about a tiny fuse( marked "TH" ) that blows and it controls the signal to the screen (inverter?). I was thinking this was the reason for the problem and easily correctable with a jumper. Anyone concur?
