You may be getting TV signals from two or more regional transmitters at your address. It may be that your preferred services are appearing lower down the list of channels than you expect, in the 800s. If your box or TV has a ‘favourites’ function, you can save these channels in this so that you can find them easily. Alternatively you can manually retune your box or TV to select your preferred regional service. If this does not help, contact the manufacturer of your equipment for support.
