Second copy of a TCL 40S4690 firmware set, marked (2), also for a 25Q64 serial flash of 64 Mbit. The RAR is 6.04 MB, the same size as the first copy, so it may be a duplicate or an alternative dump taken from another set. Compare the two images before choosing one. Write it with a programmer such as a CH341A or RT809H after saving the existing chip contents. Check that the extracted file is exactly 8 MB and that the main board in the set matches the donor board.
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 @led_software. Enginerys does not host this file.
