Check your cables
Head around the back of your TV and check the aerial cable is securely connected.
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.
Check your internet connection
Make sure your TV is connected to the Internet. See the Sony support site for help with this
Check the channel
Make sure you are trying to access the service from one of the ‘on-air’ BBC channels. If the channel is ‘off-air’ the Connected Red Button service will not be available. Try using another ‘on-air’ BBC channel.
Restart your TV
The old “switch it on and off” routine. Overused but it can often help resolve the issue. Press and hold the ⌽ Power button on your remote for 8 seconds, then let go. You're TV will then begin to restart.
