Thanks for your post and apologies to hear that you are having an issue with your Catch Up.
I've taken a look at the account to see what's going on and currently, all signal levels and power levels are looking good. The tuners however are needing some attention so we'll need to get an engineer out to give the box some TLC.
I've sent you a private message to arrange a suitable appointment
