Just out of curiosity,could you try
ffmpeg -i input -c copy -map 0 output.mp4
 And see if that works with the TV?
I doubt that the lack of colour information would cause the TV to not play
I'm assuming that it is MP4 as you haven't shown the full console output so
I don't know the container, but perhaps just rewrapping it in a new MP4 or
mkv container will do the trick.
