Firmware dump for the Sony KLV-22P402B LCD TV, stated as 16MB, inside a 27.5 MB RAR archive that likely holds more than one file. TV main boards store their software on SPI or NAND flash, and rewriting it with a programmer can fix boot loops, a stuck standby LED or no picture. Check the flash chip on your board, read and save its present contents, and confirm the image is 16MB to match the chip capacity before writing any file from the archive.
