"Backlight stopped working, iBook G4"에 답변Thanks, guys. My backlight would go out whenever I moved the display, but I could faintly see my desktop on the screen. I took it apart and inspected the inverter cable, hoping to see obvious damage, but didn't see any. After I started to peel back the shielding on the cable, the red wire must have been worn down to a single thread because it came right out, broken about an inch down into the shielding. I replaced the cable, and all is good now!
