Here's the story:


I have a early 2009 Macbook (actually it's my wife's). Suddenly the screen backlight has started turning off. If I reset the SMC I can usually get the backlight to come back on for a short time, but it is not permanent. I took it in to the genius bar (where they told me about the SMC reset procedure), but they couldn't tell me what was wrong. They suggested some possibilities such as Inverter, inverter cable or screen and wanted ~ $300 to fix. I hate to send it in and pay a fortune for a repair when it may only be just the cable or inverter. I'm also concerned that if none of those things fix it that I wasted $300. I am tech savvy and am a PC guy (sorry Apple), and can do a repair myself if needed. If it doesn't pay to try and fix, I'll buy my wife a macbook pro and try to sell the macbook for parts (or use it connected to an external monitor). If anyone has any suggestions/recommendations about what I should do I would be very appreciative.

MacBook, Mac OS X (10.5)

    Lee, based ONLY off what I've read I would suspect either the inverter board or cable. It could be something as simple as a bad connection. If you want to tackle it yourself take a look at the guides at either

    Or Both have step by step guides for just that.

    Lee, I'm sorry for your misfortune and hope my post didn't convince you to spend money needlessly. You've got a obvious hardware problem and being somewhat of a tech yourself, you know those can't be diagnosed online. You could try running the Apple Hardware Test to see if it reports anything.

    Got the news today that my MacBook has a dead logic board so I'm not the happiest camper either. I don't know what else to suggest, Sorry.

    That's great, I'm shopping for a logic board. I've decided that I want to try to fix it even though it looks like a difficult repair.
