TV firmware dump with the short name LO42XRDBB, which likely refers to a 42-inch model, although the name gives no brand or board details. The 1 MB size matches an 8 Mbit SPI flash such as a 25-series chip. Technicians reflash such images with an SPI programmer to fix boot failures, dead standby or bad picture caused by corrupt code. Since the name is sparse, compare it with the chip contents and board markings carefully, and always back up the existing chip before writing.
