Because these are community-uploaded files for TV repair, they are rarely on official manufacturer sites. You can find firmware for this board on the following community platforms:

: Place the extracted firmware file directly onto the root of the USB (not inside a folder). Flash Firmware : Turn off the TV. Plug the USB into the TV's USB port.

firmware on a Full HD panel will result in a distorted or blank display.

: Since your file is "part4.rar," you must have all other parts (part1, part2, etc.) in the same folder. Extract them using a tool like WinRAR to get the single .bin or .img firmware file. Format USB : Use a 4GB or 8GB USB drive formatted to FAT32 .
