I was recently given a 15" 400 Mhz PowerBook with a "busted" screen and latch. Appearantly an airport security officer tried to open it without pushing the latch release, breaking the case and blitzing the screen. Now here is my question: Although the screen shows no physical damage it appears blank when the machine is on. Yet, when looking closely, it is clear that the display is working fine, but looks the same as when the brightness is turned all the way down. When i shine a bright light either through the apple logo on the top of the case or hold it close to the screen itself i can clearly see the immediate illuminated area. Is this an example of a totally wrecked monitor or is this a problem new inverter board might fix? I would love to fix it myself, but i don't want to buy parts that won't solve the problem. Any thoughts?
