Small 70 KB PDF datasheet for the SF064VT2 part with the INV suffix, which in display documentation usually refers to the backlight inverter. It belongs to a set alongside the VGA and ADV sheets for the same model. Inverter documents normally list input voltage, enable and dimming pins, and output characteristics for the lamp, useful when a screen is dark but the image is faintly visible. Check the inverter board marking against this part number and take care around the high-voltage output during measurement.
