further to my comment about possibility of CFL bulbs dying over time, [http://tinyurl.com/y499uf|this article] talks about this issue, in reference to a PowerBook G3 Pismo. The article describes how replacing the inexpensive CFL lamp can fix dim or uneven lighting (or even pink screen) caused by a dying bulb. note at the bottom of the article there are also links to other info about CFL bulbs. inverters and related topics.
