RAR archive of about 9.65 MB labelled VS.TP53U71.2 with a 1920x1080 resolution tag. It appears to be TV main-board firmware for a universal board, built for a Full HD panel, though the name does not say what the archive contains. With universal boards, the firmware has to match both the board and the panel resolution, otherwise the screen may show nothing or a distorted picture. Check the board marking and panel specification first. Back up the existing flash contents before you write anything new.
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.
