PDF schematic of an LCD backlight inverter built around the OZ9926 controller, roughly 4.05 MB. The name gives no device brand or model, only the controller, so it serves as a reference for any inverter board using this chip. OZ99xx parts are CCFL backlight controllers from O2Micro. Technicians use such diagrams to follow the supply input, enable and dimming signals, and the drive to the transformers when a screen goes dark shortly after power-on. Compare the board layout before relying on its values.
