Backlight inverter schematic for the Sony KDL-40S3000 LCD TV, delivered as a 110 KB PDF. The drawing covers the circuit that powers the CCFL lamps, useful when the picture vanishes after a few seconds or the backlight never starts. A technician can check the inverter controller, MOSFET drivers, output transformers and lamp current feedback against it. A related file covers the power supply of the same model. Compare the board code on the inverter in the set with the drawing first, since inverters often came from different suppliers.
