I've spent at least 2 hours looking around online and have seen all sorts of nice circuit layouts for different inverter topologies, but not a single one had any component values in them. so does anyone have a detailed circuit to drive lcd screen ccfl's from a simple ac or dc input? or better yet, a site where someone has gone through the diy stuff including # of inductor windings. I have a bunch of the proper transformers from tv's and monitors so i don't need to wind those. i know i could just buy inverter boards for a few bucks but 1. i am broke, 2. i learn so much from building stuff, and 3. i know i have the parts already.
any help would really be appreciated. i've been wanting to do something with the salvaged lamps for a while, and today my nice desk lamp bit the dust after 10 years, so now's a good time.

Have you tried looking for "Royer Converter"? You can find several circuits with specified parts (apart from the transformer, unfortunately). I've reverse engineered a simple CCFL inverter recently, but I can't find the schematic right now.
