Firmware for the Supra STV-LC28T850WL LCD TV with an MT31LB main board, paired in the name with the LVW280CSOT E8 V1 panel. Panel matching matters on these sets, because a dump taken from a unit with a different screen can produce a wrong resolution, inverted picture or no image at all. The 6.46 MB archive is meant for programming the board's flash chip with a USB programmer. Read and store the original memory first and check the board marking agrees with the file.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @led_software. Enginerys does not host this file.
