Firmware package for the Shivaki STV-32LED14 LED television, built on the TP.S512.PB83 mainboard with a CX315DLEDM panel, supplied as an 8.99 MB RAR archive. TP.Sxxx.PBxx boards are generic Chinese TV mainboards, and the same board runs many different panels. That makes the panel code important, since a dump for another panel can give a wrong resolution or a blank screen. Check the board marking and panel label, back up the existing flash, then write the image with a programmer or by USB update where the board supports it.
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.
