Freeview intermittent interference

When you get occasional sound loss or picture freezes

When you get occasional sound loss or picture freezes
published on UK Free TV

There are several different types of interference that cause problems. This page deals with the situation where:

  • Freeview reception is perfect or near-perfect most of the time
  • The audio on TV and radio channels mutes momentarily a few times each minute
  • The picture on a Freeview channel freezes a few times each minute


There are two main causes of this type of intermittent interference:
  • 'Induction' interference
  • Mobile phone interference


Induction interference

Induction interference is caused by mains-powered household devices that contain a large motor, such as:
  • Washing machine;
  • Tumble dryer;
  • Central heating pump or combination boiler;
  • Fridge;
  • Freezer;
  • Power tools (drills, jigsaws etc)
  • Vacuum cleaners;
  • Water pumps;
  • Automatic doors


You can identify if one or more of these devices is causing the Freeview reception problem by powering off the devices.

If one of these devices is causing the problem, then the reception problem can usually be solved by using a mains filter device and use it on the Freeview boxes mains connection.



Such as device is this: Maplin: 6-Way Flat Screen and HDTV Surge Protector and Mains Filter.

Mobile phone interference

If you keep a mobile phone by your Freeview box or digital television, keep it further away!

This also applies to other transmitters such as baby monitors, video senders, walkie talkies, and portable phones.

Guy, Eric, Alan, et all:

It has been suggested that the recent warm days have given rise to atmospheric conditions that can disrupt TV reception. As there are many similar reports from around the southern part of the UK, that would seem to be quite likely. Do NOT retune your TV set under such situation.

For about one month we have had pixillated reception from time to time - we also get breaks in radio programmes. We live near the centre of Hemel Hempstead. We have followed the instructions regarding returning to factory settings deleted all channels and started again as per the instructions on this site but there is no improvement. All advide welcome.

Elizabeth Driver:

To assist with this type of problem contributors need to know your location more accurately as Hemel Hempstead is a large area. Do this by providing a post code (or that of a close by shop or post office) so we can then examine which transmitter would likely be best for you and whether there are any known problems with that. Also whether there are any reception problems due to hills, buildings, etc.

Have you asked your neighbours who also use Freeview whether they are having the same problems? If they are not then you may have a problem with your aerial system, the cabling or the TV set itself.

I can no longer find radio programmes, channels 700 on Freeview. Anything I can do to get them back. I have rerun the installation. They show up when searching but not there when installation finished.
