I'm working on my friend's 12" ibook with a very dim screen. Since there was some light, I assumed that it's not the inverter, but that the cold cathode was near the end of it's life. I ordered a new one and installed it. It's very bright (cuz I can see the light from it through gaps in the casing, so it's not the cathode or the inverter, because the LCD screen IS STILL DIM. I adjusted the display settings to the brightest possible.

I'm not a Mac guy (as u probably guessed), so if someone knows about a "secret" display brightness setting I'm missing, feel free to let me know. Otherwise, I'd appreciate any other hard ware related suggestions. Could the issue be due to a fault of the display chip on the motherboard?

I know that I broke the holy covenant of "never open your own mac", but I fix PC desktops and notebooks all the time, and this mac practically invited me to tear it open with those convenient hex bolts on the sides of the display.

Thanks mac peeps.
