[QUOTE="cwa107, post: 1170409, member: 24098"] Most of the time, those kinds of issues are caused by the inverter. The inverter is a step-up transformer that increases voltage from the battery to power the CCFL tube backlight. Those CCFL tubes rarely go bad in my experience, and are usually rated for tens of thousands of hours. The inverters, on the other hand, do have a tendency to fail - which is why I'm glad that most of the industry is moving onto LED backlighting. Replacing an inverter is usually pretty simple stuff. I have not done it in a Mac, but typically it involves removing the display, removing the bezel around the screen and popping out a tiny circuit board that is held in with just a couple of screws and has two wiring harnesses running into it. For most laptops, it's a 30 minute job - less if you're mechanically inclined. You should be able to get the details, parts, tools and model-specific instructions here: [url=http://www.fixit.com]FixIt.com | Fix It | it solutions | it business[/url] (and I'm not affiliated with them in any way, aside from being a customer).
