Inverter documentation, judging by the INVT suffix, for the SFD064VT2 part, 171 KB in PDF and catalogued as a datasheet. No electrical values or brand appear in the name. Typical content covers supply input, enable and dimming control and output characteristics for the backlight. That is handy when a screen stays dark, the backlight cuts out or brightness control fails. Measure against the listed operating conditions, and check the VT2 code on the unit, since VT4 has its own inverter sheet.
