Gang, I need FAST HELP here as it's the final day of the logic board extension program that I'm nearly certain I qualify for. I just got off the phone with Apple tech support and they believed the problem to be a backlight issue when, in fact, based on everything I've read, the problem stems from a faulty logic board. This has been going on for many months, but I've only recently looked into the free repair program. Anyway, I've noticed that my screen dims and comes back, dims and comes back, etc (and oftentimes just stays dim for hours). It lasts for many minutes at a time in each direction. I also have a line on the upper left-hand quadrant of my screen that's about four inches long. Apple had me reset the power manager and then boot into the system disc. No luck. Apple believes the problems to be related to the display and backlight and said that they didn't fall into the logic board extension program. Is there anything I can do? Today's the LAST DAY of the program! I'd really love to get this machine fixed (Dual USB iBook). HELP!
