What's Happened To Our Tv Channels

[grandpajoe]

Discussed earlier in the week.

You'll need to retune.

Can you try the same thing again to see if it completes?

Failing that contact your provider.

What do you mean by 'upgrade' ? I haven't retuned yet, but I've only lost 7 which I'm not bothered about as I never watch it.

[grandpajoe]

Re tune sorry not upgrade! Doh

Ok grandpajoe, not sure why you've lost all those channels. Maybe do it again and watch what happens as it's going through the process. With mine, the TV comes straight on again after it's finished re-tuning. Good luck.

The channels you're missing are all on the PSB2 multiplex ( = 'bundle of channels"). Each multiplex uses a different frequency. In theory you should have a different aerial for each multiplex (so that the elements are exactly the right length to 'resonate' with the relevant frequency). In practice though we all use just a single aerial, which is bound (by the laws of physics) to be better at 'resonating' with some frequencies than with others. Your aerial clearly doesn't resonate well with the frequency that's being used by PSB2.

Either PSB2 has migrated from a frequency that your aerial 'likes' to one that it doesn't or the power level used to transmit PSB2 has been reduced. (A lot of the retuning that's been necessary with Freeview services is related to the rollout of 5G mobile phone services which, as well as involving frequency changes for Freeview, has also required a significant reduction of the power used by some Freeview's transmitters in order to avoid interference to 5G services).

Either way, the problem you're now facing is one of insufficient signal strength for the combined needs of your aerial and your TV. You might need a new aerial installed but it's far more likely that you can solve the problem simply by installing one of these:

(You'll also need one of these to go with it https://www.screwfix.com/p/fly-lead-coaxial-plug-to-plug-1m/41720 and you should carry out another retune after fitting them).

Thank you everyone. It's now sorted by the simplest of means!! "Role Reversal" This evening I went to the supermarket food shopping and left my wife scratching her head about the TV. When I got in with what we needed plus 18 cans of cider my wonderful wife had sorted the TV . Went online and asked BT TV what to do and it talked her through it. Sorted!! I'm on mi 5th can.....

That was Husband's approach to technical matters at home grandpajoe - worked for us too. :-)

That's good grandpajoe x
