ZIP archive of 4.54 MB labelled LP24B, a code that appears to refer to a TV or monitor model or board. The file name gives no further detail on contents, revision or chip type. Archives of this size in a repair index usually contain an SPI flash dump or service files used to revive a board that will not boot or shows no picture. Extract it, see what the files are, and match the board markings and flash chip capacity before programming. Always save the existing chip contents first so the original can be restored.
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 @gunvantrathore. Enginerys does not host this file.
