Firmware archive for the Panasonic TX-L32C20LA LCD TV with the TNP0EA017 main board, revision 8A. The memory listed is an H27U1G8F2BTR, a Hynix 1 Gbit NAND flash, and the archive is 11.5 MB. Repairers use such dumps to bring back boards with corrupted firmware, start-up hangs or repeated reboots. Writing requires a programmer that supports this NAND and an appropriate adapter. Read and keep the original contents before programming, and check that the board code and revision printed on your PCB match.
