Freeview intermittent interference

When you get occasional sound loss or picture freezes

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

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



There are two main causes of this type of intermittent 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: <img src="data:image/png;base64,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" class="xico" style="vertical-align:text-bottom" alt="www.maplin.co.uk link icon"> link iconMaplin: 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.

The picture on our Samsung TV in the lounge continually breaks up/freezes but the Samsung in the bedroom is fine, they are both connected to the same roof aerial. Brought one from bedroom into lounge & it works perfectly so thinking it's not an aerial problem. Any ideas/advice before I go buy a new TV for the lounge please.

Jan: Your only 13km from Crystal Palace, so check the lounge TV's signal level - if the Samsung's are different models, their tuners may have slightly different thresholds when it comes to signal strength. Its likely that the signal strength is just too high. Search for 'too much of a good thing' on this site, and go from there.
