Small firmware archive of 94 KB for PS43D455A2M, marked U2010 and the Macronix MX25L1635D flash chip, a 16 Mbit (2 MB) SPI serial memory. The model code resembles a Samsung plasma TV mainboard, though the name does not say so outright. U2010 is probably the board location of the flash chip. Repairers use such a dump to reprogram a corrupted chip with a programmer supporting the MX25L1635D. Save the existing contents first and confirm that the extracted image size equals the chip capacity before writing.
