Freeview Help: Missing Channels

The Freeview channel line-up and channel numbers change now and then.

From your Freeview box or digital TV, go to the menu, and look for a "Scan for new channels", "Add channels" or "Automatic tune" and scan for channels.

If you're not sure on how to scan for channels, look in the manual. Help on scanning for channels

Are you able to get all of the Freeview channels where you live?

Not all of the UK can yet receive all of the Freeview channels. Check that all of the Freeview channels are actually available in your area, using a postcode checker. Enter your postcode at www.freeview.co.uk/availability

See our "Freeview coverage" section for help.

Do you get your Freeview from a small local relay transmitter? If so, you may not be able to get all of the channels.

Around 90% of UK homes will be able to get all of the Freeview channels, but there are some homes that rely on a 'relay' transmitter for their Freeview signal. Relay transmitters are often used in small rural areas where signals from a larger transmitter aren't good - typically where signals are blocked by hill or mountains, or where homes are in a dip or a valley.

Smaller relay stations upgraded for the digital switchover are only able to transmit three of the Freeview multiplexes, the Public Service Broadcast ones, so those using a relay transmitter will be able to see services such as BBC One, BBC Two, ITV, Channel 4 and Channel 5, but not channels such as Dave, Sky News, Yesterday and Film 4.

If you have more than one Freeview receiver, and/or more than one aerial point in the house, try a few experiments

• If the problem is there for all aerial points and Freeview boxes, then it could be signal coverage, a problem with your aerial, or a problem with your aerial cabling
• If the problem only affects one room or receiver, then it could be an internal cabling problem, or interference, which can often be resolved with a booster

Many Freeview boxes and digital TV sets let you see an on-screen display of your signal strength.

If your signal is weak, but you're meant to be in a decent signal area, then that points to a potential problem with your aerial , or an issue with your cabling.

In some cases a signal booster can also help to improve a poor signal.

If you have lots of aerial extension leads, splitters and adapters, this can affect your signal quality. Using long extension leads can also affect your signal.

'Looping' your aerial feed through lots of equipment, such as video or DVD recorders can weaken the signal too.

Give your receiver the best chance at getting a quality signal - See our cabling advice to eliminate any weak links in your cabling.

It's often worth trying a basic connection, bypassing any extension cables, splitters, recorders, etc. Connect the main house aerial direct to your Freeview receiver - if a basic connection works, it could indicate a cabling issue.

There are several factors that can affect your signal and cause interference, including cabling problems, weather conditions, electrical appliances, taxicabs, passing cars, scaffolding, etc.

Normally this is shown as picture break-up, pixelation or loss of sound, but it can cause you to lose channels if it's particularly bad

Go through the steps on our "Interference" page if you're suffering from this.

It might be worth checking whether your neighbours are affected. If they can get the channels you're missing without a problem, and their aerial is pointing at the same transmitter, that may confirm that the problem is with your aerial or aerial cabling.

Double-check whether there's any transmitter work being done in your area that might affect you. The BBC have a handy Transmitter Maintenance Page.

For best results, you need a good quality rooftop aerial, pointing at the appropriate digital TV transmitter.

Indoor aerial: Set-top indoor aerials and loft aerials often are not up to the job

For aerial advice, see our aerial section.

If you find that you just can't receive channels on a certain multiplex, there's a chance that your aerial isn't capable of tuning in some of the Freeview signals. Check the 'band' that missing multiplex is in (using Wolfbane.com), and verify whether your aerial is designed to work with that frequency 'band'. It could be that the Freeview channels are outside that band - For more on this, see our Aerial Group section.

Some equipment, such as video recorders and Sky digiboxes use something called a modulator to 'broadcast' a signal that equipment like a TV set can tune into. In some cases, the channel number used to modulate on (a number from 21-68) can be the same as one of the Freeview multiplex channel numbers.

To test if there's a chance of this, try removing other equipment - making the connection as simple as possible. Connect the TV aerial to Freeview box, then a SCART to the TV (cutting out other boxes and video recorders). If the missing channels appear, then it could be a channel clash and you may need to re-tune the modulator to a new channel.

If you live close to your TV transmitter, you might find that your Freeview box or TV is getting too much signal and this could be 'overloading' your receiver.

If this is the case, you may need to get an Aerial attenuator. These plugs into the aerial socket and reduce the incoming signal.

Also, if you needed a signal booster prior to the Digital Switchover, you may no longer need this, and should experiment with removing the booster to reduce the signal.

Check that your aerial is plugged in to the Freeview receiver correctly. If possible, make a direct connection to the TV aerial (i.e. nor via adapters, or looped through other TV equipment).

Also - reset your receiver - If you are using a Freeview set-top box, switch it off at the mains for 30 seconds, then turn it on again.

The Freeview channel line-up and channel numbers changes now and then, and you may need to update your channel list.

If a channel has vanished, perhaps it's no longer broadcasting? Also, occasionally channels get renumbered, are renamed, or move to a different channel block (known as a multiplex).

Check our Freeview channel list, and also see our Freeview News Page for announcements of changes to the Freeview lineup.

If it's just one or two channels that are missing, you may find that you need to get your Freeview box or TV to 'rescan' for the Freeview channels. This means that it will search for changes to the lineup and update the channel list. To do this, go to the on-screen menu, and look for a "Scan for new channels", "Add channels" or "Automatic tune" option.

Sometimes, you may have to try this a couple of times, or reset your box first. Need help with rescanning?

Are your neighbours affected too? Is there any transmitter work being done in your area that might affect you - check the BBC Transmitter Maintenance Page to see if there's something that is affecting your local transmitter.

Not sure which transmitter is nearest to you? Check by entering your postcode at Wolfbane.com

If you have more than one Freeview receiver in the house - check whether the channels are also missing on a second receiver. That can help to identify what the problem is.

• If you try two receivers on the same aerial connector and they both have the same problem, then it's a signal or cabling issue, not a box problem.
• If the box works in one room, but not another room, then it could be an issue with the cabling for that room, or that the signal needs boosting to that room

If it's only one Freeview receiver that's affected, and others in the house are OK, then check the aerial cabling to make sure all is well. It could be that if you're splitting the signal to multiple TV sets, you are experiencing "signal loss" through the cabling.

A boosted splitter can help in these situations. See our Boosters page.

Any chance of aerial damage? Rain in the aerial cable, or wind dislodging your aerial will have an affect on your signal quality. Worth checking your aerial is where it should be, and that the aerial cable has not been damaged.

Check the path from your aerial to your receiver:

• Could any splitters have got unplugged?
• If you have a signal booster, has it been unplugged or is no longer working?
• Has your aerial lead got unplugged, chewed by a dog, cut through?

If in doubt, try a basic connection. Connect aerial to receiver, then receiver-to-TV (bypassing any other equipment, connectors, splitters or boosters).

Storms, heavy rain and snow can affect your signal. Some of our interference tips may help if this affects your viewing regularly.
