Got new box and after pairing with old handset it only works for that day.. every morning it's unpaired again..new batteries, checked wired paired again..and next morning handset not paired..day 5 I'm giving in...help
Was the old box also a V6? If it was one of the old Tivo's you should have been sent a new remote.
One of the Forum Staff posted this workaround for remotes which seems to work for most people having issues with the pairng.
If you go to HOME > Help and Settings > Help > Set up Remote. Follow instructions there it should give you a series of codes to try. You can also put 0999 in place of the code and press channel up until the TV turns off, then press ok.
