Large RAR archive of about 632 MB, apparently a USB update or service firmware package for a Moonx 43-inch TV model 43AH700, with 516 likely a board or software variant. The size suggests a complete system software image rather than a small SPI dump. Packages of this kind are usually copied to a FAT32 USB stick and loaded through the set's service or forced-update procedure. Confirm that the main board and panel match your unit before starting, because loading the wrong software can leave the set without picture or stuck at boot.
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 @tvcodeservice. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
