Freeview intermittent interference
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.

Re-tuned after prompting on ch 15 to get film 4 on free view TV. Now only receive BBC 1 and 2 correctly.
Other channels intermittent, pixilated and clicking noise. Have tried retuning with aerial out and again when in situ with no change. Think I am on huntshaw receiver at EX39 3NX.
Any help please.

Last evening and this morning, all freeview channels are losing signal, sometimes every couple of minutes. We get a blank screen, sometimes the "no signal" message. Neighbours report the same problem but Huntshaw website says no problems. What is happening?

I have progressive picture and audio break-up on my kitchen TV, mainly BBC2 at about mid-day. No mobile phones or fridges/washing machines etc switched on. I switch off the on and all is then OK.
Could the cause be a microwave that is housed immediately under the TV? Only thing I can think of, but would this come under the "large motor" effect?

Alan Walton: There is one way to find out - try watching the TV while swiitching the microwave on!
Of course it might not be that at all. Check singal levels, etc (is the signal too strong?) - and a postcode is a help, since you can see if your in a marginal area, etc.

Hi,
We are having problems with our tv's at night more than at any other time....the signal strength fluctuates between 0 and 70% ish but the picture will freeze/go fuzzy with brightly coloured lines and marks across it before we give up and turn it off. We have 3 tv's that are affected and it is always at night....we have checked the ariel and bought a new booster but all seems fine and they work during the day??!!
Please help!

Emma:
Your location postcode would be a good starting point.
Also where is the aerial fitted ie chimney, side of house, loft

Hi Jamie,
