A 5.01 MB RAR package labelled for the TCL 32B2600 LCD TV. The file name lists no board, chassis or firmware version, so the exact contents remain unknown until extracted. Such TV archives usually contain NAND or SPI flash dumps, EEPROM data or schematics used to revive a set stuck on logo or in a boot loop. Read and keep the factory chip contents before flashing anything. Also check that the mainboard marking and panel type match, because a dump from another chassis can leave the set without picture.
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 @hashmielecom. Enginerys does not host this file.
