Duplicate copy of an 8.00 MB LG 22LB470A-TE firmware image, with the suffix (1) added to the name and the same LW45A and LL45S codes, probably chassis and board references. It is worth comparing it with the original copy by checksum to confirm the two files are identical. The image is meant for writing to the TV main board SPI flash with an external programmer when the set hangs at the logo or fails to start. Read and save the old chip first, and check that the flash size matches before programming.
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 @bios_bin_file. Enginerys does not host this file.
