That code means not a usable signal or the box can’t read the signal. What was wrong with the previous box?

Started having to reset it about weekly, then got the welcome screen with green "snow" and no service. All of our other boxes and tvs worked fine and I could still get tv apps like netflix. Just thought I had a bad box.
