How To Set Digital TV in Kenya

The switch to digital television broadcasting in Kenya is now complete, with the analog TV signal having been switched off across the country. This transition from analog to digital TV was part of a worldwide effort to free up radio spectrum for more advanced services and improve broadcasting quality.

In Kenya, the migration process began in 2009 when the first digital TV services were launched in the country by private broadcasters.

The state broadcaster KBC started digital transmissions in 2013.

The National Communications Authority gave broadcasters and consumers sufficient time to acquire the necessary equipment and prepare for the analog switch-off.

The full transition to digital TV in Kenya was completed in June 2022 when the analog TV signal was permanently switched off. This marked the end of analog TV broadcasting in the country after more than 50 years.

The move to digital TV provides significant benefits to broadcasters and consumers, including better picture and sound quality, more channels and interactive services.

Pixelation and Picture Freezing

Patchy pixelated video accompanied by picture freezing indicates low/erratic signal levels.

Actions to improve reception:

  • Check antenna cable for loose contact, damage, moisture ingress.
  • Install higher gain directional outdoor/attic antenna aimed at transmitter.
  • Upgrade coaxial cable to thick RG6 type to minimize signal loss.
  • Fit mast-mounted line amplifier as close to antenna as possible.
  • Increase antenna elevation using taller mast if located in low lying area.

No Sound

Loss of audio but normal video points to a sound setting issue.

Troubleshoot as follows:

  • Check audio output connection from STB to TV.
  • Change TV audio settings from speakers to external audio system.
  • Adjust volume levels on STB, TV and audio system.
  • Some channels may not have audio transmitted – test another channel.
  • Reset STB and redo audio setup wizard.

Remote Not Working

First change batteries on remote. If still unresponsive:

  • Check for obstruction between STB infrared sensor and remote control.
  • Point remote directly at sensor panel on STB.
  • Try using remote from close proximity to STB. Faulty remotes have short range.
  • Reroute or eliminate sources of infrared interference near STB.
  • Attempt pairing remote again with STB using setup menu.

Unable to Access Some Channels

If you are missing channels that should be available in your area:

  • Check regional transmitter coverage maps for channel broadcast area.
  • Rescan for channels in case network parameters changed.
  • Try re-orienting antenna for maximum signal strength.
