Dump archive for the Panasonic TX-PR42C21 plasma TV, linked to board TNPH0829 and plasma panel MD-42LH13PE1. At 169 KB the RAR is larger than a typical EEPROM file but small for full firmware, so open it to see which memory it targets. Such files are used to recover a set with corrupted data that shuts down or fails to start. Verify the TNPH number and panel code on your unit, and read the original chip with a programmer before writing, keeping that copy safe.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @tvsoftwareworld. Enginerys does not host this file.
