1. Check all cables
Head around the back of your box and check the aerial cable is securely connected to the Aerial In/Antenna In port.
Don’t forget to check the other end of the aerial cable is also connected to the aerial socket in your home.
Using an indoor aerial? Some of these are powered aerials, check the plug is connected and the aerial is powered on.
Also ensure your Ethernet network cable is securely connected between your YouView box and the router or powerline adapter. This error code also appears when you have an issue with an internet channel so it is important to ensure a good internet connection.

2. Retune your channels
Bring up the menu with your remote
- Select Settings*
- From Signal & Connection select TV Channels
- Select Retune Channels**
It can take a couple minutes to tune. Don't worry, we'll let you know when we're done.
Please note that it is not possible to manually retune the box.
If you've retuned and your signal is still on the low side, have a look through the steps in our How to improve your signal article.
If you have any trouble with retuning your YouView box or you've lost some channels, please contact your box provider or internet service provider.
*Settings can be found via the cog in the top right corner of the Menu. You can get to the cog by pressing Up and right after opening the Menu.
3. Restart your box
The old “switch it on and off” routine. Overused but it can often help resolve the issue. Press and hold the 
button on your box for 8 seconds, then let go. You’ll be greeted with a friendly ‘Hello’ telling you that your box has restarted.
4. Planned Engineering Works
Every so often maintenance works are carried out to keep your transmitter in top condition. This might weaken your signal or interrupt your service.
Check the Freeview website to see if your transmitter is affected.
Don’t know what transmitter you’re using? Pop your postcode into the Freeview home checker to find out.
If your area has multiple transmitters available, you can find out if there's any transmitter faults and see the signal strength of the alternative transmitters on the BBC Reception Check website.
5. Check your signal
The signal from your aerial might not be strong enough.
- Select Settings* from the Menu
- Select Signal Quality from Signal & Connection
If your signal quality is below 50% you may start seeing issues with your picture. Have a read of our article: How to improve your signal for more information.
