Flash dump taken from the main board of a JVC LT-55KB66 television, marked T.MS3393.81, stored as a 4.00 MB BIN file. The image is meant to be written directly to the board SPI memory with a hardware programmer. Typical uses are reviving a set stuck on the logo, curing a standby lockup or restoring the proper panel settings after a failed update. Confirm the board marking and screen model match yours, and read and keep a copy of the existing firmware before you overwrite anything.
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.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
