RAR archive of firmware for the LG 26LN4100 television, TA region variant, about 11 MB in size. It probably contains a mainboard flash dump, possibly with an EEPROM image, which is used to restore a set that will not boot, loops at the logo or has lost its settings. Unpack it and check which chip each file is meant for. The capacity of the image must match the flash device on the board. Read and store the original contents first, then write with a suitable SPI or EEPROM programmer and verify the result.
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.
