RAR archive of 3.93 MB labelled only with the board code P50-D68V3.0, apparently a TV mainboard with version 3.0 in its marking. No brand, screen size or content type is stated, so open the archive and identify the files before relying on them. If it holds a firmware dump, it would usually be written to the board's flash with a programmer after backing up the original chip. Check that the code printed on your PCB matches, as panels and configurations vary between sets using similar boards.
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 @hrtechno. Enginerys does not host this file.
