RAR archive for a Joyard board, apparently version 10, where AN TU140 seems to reference an AN-variant TU140 platform, likely firmware for a display or TV mainboard, though the device class is not explicitly stated. At about 24 MB it probably contains a flash image and possibly support files. Extract it and compare the board marking and flash size with the hardware. Read and save the existing chip contents with a programmer before writing, because panel settings and keys are often stored there.
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 @boardsscanrepo. Enginerys does not host this file.
