A: This usually means the TV did not detect the USB drive or the firmware file. Double-check that the USB drive is formatted to FAT32, that the file is named exactly install.img , and that it is in the root directory. If all of that is correct, the file may not be compatible with your TV, and you will need to find a different version.

Press and hold the physical Power button located directly on the TV panel frame (not the remote control).
