Unable to get talkback on tv programmes

[Claude1]

Hi

I've activated talk back facility successfully but when changing channels it is not telling me what the programme is or the duration. Any ideas please?

Hi @Claude1, what is the model name of your TV? You can use this link to help you locate the model name: https://www.sony.co.uk/electronics/support/articles/00248604 

Also, are you watching digital channels on live TV or is it input from a TV box?
