What do I do when I see a “NO SIGNAL” message on one or more channels?

First check that your TV is set to the correct Source or Input, try changing the Source or Input to AV, TV, Digital TV or DTV if you haven’t already.

If your “No Signal” message is not due to incorrect Source or Input being selected, then it’s most likely caused by a set up or antenna fault.

In the majority of cases, pixelating pictures ("blocks on the screen") or a "No Signal" message from time to time are symptoms of reception issues.

Network Status

There is essential maintenance carried out on the network from time to time, which may have a temporary impact on signal levels. However these are usually scheduled between midnight and 6am to avoid causing disruptions to your viewing and you can find information about all projects that may affect the network status here  (information as provided by the Transmission Providers).

Common Causes of Reception Issues

Reception problems can be caused by:

Fault with the antenna, for example:

  • UHF aerial is incorrectly aligned or obstructed
  • Satellite dish is incorrectly positioned or obstructed
  • Corrosion in parts of the antenna due to constant exposure to the elements;

Fault with the cabling or connections, for example: 

  • Loose connections from the antenna cable to the TV; 

Product fault or misuse:

  • You may wish to contact the manufacturer of your device to check, for example, does your product have the latest firmware upgrades?

If you have regular reception issues your antenna system should be checked.

First try a "Cold Retune"...

  1. Switch off your device at the wall (this is the receiver, recorder or TV that your antenna cables is connected to)
  2. Reconnect all cables at the back of the TV or box, making sure that the cables are all properly connected (you want to avoid loose cables that could cause signal loss) and if you have a signal booster connected, try removing that and plug the antenna cable straight into your receiver, recorder or TV.
  3. Wait a little while for any overheated devices to cool down.
  4. Power ON your TV and receiver / recorder box.
  5. Retune your device.  You'll find tuning options in Menu or Settings. If you need instructions, please refer to your Device Manual, or for guidelines, see here.

If this doesn't help, it's most likely there's an antenna fault at play here.

Our recommendation is to contact a local installer in your area who can provide on-site diagnosis and fix. Here's a free online directory where you can find a local installer. It's best to ring around for a few quotes.

Alternatively you can contact Aerials Direct, a Freeview accredited installer, for a quote.
