Compressed 7z archive named after a GigaDevice-style flash part designation, GD265Q64C, with no television or board model given in the name. The 64 suffix suggests a 64 Mbit (8 MB) SPI NOR chip, so the contents are most likely a raw dump read from such a chip. Because the source device is not identified, treat it with caution: compare it to your own read, check that the board matches, and always save the original contents before writing anything with a CH341A or similar programmer. Image size must equal the chip capacity.
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 @hashmielecom. Enginerys does not host this file.
