Inverter-related datasheet for the SFD104SL3, judging by the INVT suffix, provided as a compact 167 KB PDF. It appears to belong to the same document set as the VGA and ADV files for this part number. When a panel has a dark screen but a visible image under a torch, the inverter or backlight circuit is a typical suspect. A sheet like this helps check input voltage, enable and dimming pins and the lamp or LED output. Verify the module and inverter markings match before testing to these values.
