[QUOTE="chscag, post: 1131752, member: 46727"] The reason Apple wanted $300 to replace the backlight is because it's a difficult repair requiring quite a bit of labor. The entire LCD casing has to be disassembled. Your trouble is not with the inverter, it's the CCFL tube that's bad. The inverter feeds it AC power which in turn lights the CCFL that provides the back lighting for your LCD. Recommended repair for a bad backlight is to replace the entire LCD assembly. It's actually less work and only costs a bit more. See the entire procedure at [url=http://www.ifixit.com]iFixit: The free repair manual[/url]. [/QUOTE]
