Check your cables
Time to head round the back of your box. We’ll walk you through what to do.
First things first, we need to check how your box is connected to your router. Pick your connection:
Direct Ethernet cable
Check the Ethernet cable is securely connected to the Ethernet port. To be safe, disconnect and reconnect it.
Follow the cable from your box to the back of your router and make sure it's securely connected to one of your LAN ports.
Check the Ethernet cable is securely connected to the Etherner port. To be safe, disconnect and reconnect it.
There should be two powerline adapters plugged in to your mains. One by your YouView box and one by your router. Check both adapters are switched on and make sure the Ethernet cables are securely connected.
Retune your channels
A simple retune may do the trick:
Bring up the Main Menu
Select Channel Setup
Select Digital Setup
Select Digital Tuning
Select Digital Auto Tuning
Give it a couple of minutes to retune and check to see if your signal is back to normal. You can also manually tune your channels by choosing the Digital Manual Tuning option in the Digital Tuning section.
Reset your BT TV data
You might need to refresh the data:
Open the Main Menu
Select BT player
Select Reset BT TV Data. The player will then close automatically
Reopen the BT Player
Now go back to the channel where you got this error
