My remote stopped doing RF yesterday. I have tried the following things. Making sure the receiver is still set to RF. Changing to IR then back to RF. clearmybox double red button reset re-downloading the box software reset through menu. buying a new remote at Walmart. Does this mean something has failed inside of my HR24? I have tried everything except the reset everything button. I don't want to lose all my settings and recordings since that probably won't work either. Directv did do a SW update on 1-21-21, but I don't think it would have waited a month to fail if that caused it.
