    Hi again, it has been a bit since my last post, I've had a busy summer and a ****** school year. How have you guys been? Quick question, anyone have some suggestions for some trouble shooting to help determine wether its a hardware or a software issue, and if hardware wether its the backlight or the inverter board? I'm at a dead end, since money is tight right now (15, car, license, no job thanks labor laws) I want to get the right part (if its a hardware issue) Thanks guys!

    TiBook screens and backlights are difficult to replace without damaging the metal frame. The inverter would be cheaper than buying a whole display assembly. How did it die? Is the whole screen out?

    Prior to failure, was the display slowly getting brighter and dimmer progressively? If so then I would say inverter. That being said it could be either one if it did not fail that way.

    Not that I noticed, I powered it off for a month and now the backlight won't come back on. The screen works, just no backlight.

    Adjusting the hinge makes absolutely no difference?

    Nope, none at all sadly. Its really odd, I've reset the PMU and the PRAM, no help again sadly.
    EDIT: reseated some of the connections, but it didn't help, arg. Is it really the bulbs?

    It could be but I would think the inverter is toast.

    I suggest replacing the inverter first. In most cases when the backlight is dead, there are signs that indicate it before it completely goes. The inverter is often just a quick failure with no or little signs.
