Compact archive for the Panasonic TH-P42X10S plasma television, identified with board TNPH0783. At 2.63 KB the contents are most likely a small EEPROM dump rather than a full firmware image, although the name does not state the chip. Rewriting the settings EEPROM is a common fix for Panasonic plasma sets that stay in standby or flash fault codes after data corruption. Read and save your own chip before replacing its contents, and check that the board code on the PCB is TNPH0783.
