Inverter schematic for the Sony KDL-46S3000 LCD TV, supplied as a compact 58 KB PDF. It covers the backlight inverter circuit that drives the CCFL lamps, so it is mainly useful when the picture appears briefly and then goes dark, or when the set blinks a lamp-related error. A technician can follow the drive transformers, the controller IC and the protection feedback lines with it. Check that the inverter board fitted in the set matches the one drawn, as panel suppliers differed between production runs.
