Small firmware dump labelled PS43D455A2M with a U2010 code, intended for an MX25L1635D serial flash chip. The model string looks like a Samsung plasma TV, although the name does not state a brand. The MX25L1635D is a Macronix 16 Mbit SPI NOR device, and it is normally rewritten with an external programmer when a set is stuck in standby or boot-looping. Check that the chip marking on the board matches, keep a backup of the existing contents, and verify the written data after programming.
