Large 516 MB RAR archive named only after the Samsung UN40ES6500G 40-inch LED TV model code. No board number, firmware version or list of contents appears in the name. Given its size it likely contains a firmware package or memory dumps for the set, but you need to open it and check before relying on it. Samsung TV repairs often involve reflashing eMMC or the main SPI flash when a set boot-loops or sticks on the logo. Match the main board part number on your unit and keep a backup of the original memory.
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 @DumpFileFlashUpdate4. Enginerys does not host this file.
