Image burning on my screen

Question

The word "FACTORY" is now appearing in red letters across the top of my screen. How can I remove this to keep it from burning in? It started when I got a new remote from our cable company, and even that was a fiasco---the new remote won't turn things off and on, but it will do everything else. We even had a technician come out here and try to deal with it, but no luck. And now that stupid and distracting word across the screen has us really worried about what could happen.
