I have several TVs all on the small boxes except for one. I went away for a couple of days and left my house to the house sitter. Comng back I noticed that all but one remote no longer functions with the LAST button. I can tune a channel (say 6) and then pcik another one (23). So I hit the last button and a message comes up "0" is not a not a recognied channel". What is up with that? I have more than one remote for the same tv and both remotes do the same. Is this an issue with the boxes? I have one TV set up with the same box and it works fine. Any suggestions
