Archive for a TCL 32-3010 television, stored as a 2.22 MB RAR file. The name shows just brand and model number, with no board, chassis or version information. Expect a firmware or memory dump, or possibly service documents, inside; extract it with 7-Zip or WinRAR to see the exact files. Before programming, read the factory contents of the flash or EEPROM and keep a copy. Compare the main board label with the source of the dump, because a mismatched image can leave the TV dead or with a wrong panel setup.
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.
