Model Name UE55KS7000U. We have a small but annoying problem which we hope you can help us with. We accidently delisted our favourite channel from tuned channels & having consulted the user manual we cannot figure how to re-instate it without auto-tuning all the channels which we are afraid to do. Is there an easy way to install just one terrestrial channel? Our remote (Samsung) does not appear to have a suitable button for doing this either.
