RAR archive of 1.41 MB for the TCL 32D12 television. The name shows only the model, though a companion entry of the same size refers to a W25Q32 flash, so this may be the same 32 Mbit dump; that is not confirmed here. Extract and compare it. A 4 MB image goes into the main board serial flash through a programmer to repair boot faults. Back up the original chip first and confirm the chip capacity and the board number match before writing.
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.
