Over at Hack a Day is a video and project log of an industrious fellow whose digital picture frame backlight bit the biscuit. Instead of buying a new one he removed the dead CCFL and replaced it with a six dollar LED strip instead of an expensive inverter or lamp for the CCFL. The project is not easy, especially if you wish to attempt this on a full sized monitor but there are tips and tricks that should help you on your way in the full post.
"[Fileark] had the backlight on his digital picture frame go out one day. These are generally Cold Cathode Fluorescent Lamps which require an inverter to source the voltage necessary for proper operation. When they stop working, the inverter is usually to blame. Since that circuit is made up of pretty small surface mount circuitry, he decided to replace the backlight with LEDs rather than repair the inverter."
