Many problems can be cured by simply resetting your digital box, whether it's a terrestrial (Freeview), satellite, cable or broadband box or a digital TV recorder. This also applies to digital TV sets (which have Freeview built in) and other services that include Freeview – Youview and BT Vision.
Typical problems include:
Channels change from time to time - new ones are added, some are removed and others move to different channel numbers. On Freeview they may move to different multiplexes. If you have a satellite, cable or broadband set-top box, the channel list will usually be updated automatically.
If you have a digital terrestrial box (Freeview, Top Up TV, BT Vision or Youview) or digital TV, you will need to retune it yourself. It's a good idea to do this regularly to make sure you are always up to date. You will need to retune at least twice when your region goes through digital switchover.
Retuning should also restore any missing channels or features that you think you should have.
The retuning process runs a scan and finds all the available channels. Your box may have an Add New Channels option that you can use, but this may not pick up other changes such as channels being moved to a different multiplex or removed altogether.
For full retuning instructions for your particular model of digital box, check your manual or go to TV Re-tune.
A digital box has a micro-processor and software, like a computer, and it can suffer from occasional glitches. To reboot (restart) the software:
You may need to clear your box or TV's 'memory' and retune again to find all the available channels.
If you are confident about setting up your digital terrestrial box or TV, you can manually retune it to the correct channels. See your instruction manual for details, or contact the manufacturer.
