Hi have been having trouble with my freeview through my tv. past few days was able to retune and got bbc channels, but they were unwatchable, now when i do a scan no channels are being found and says to check antenna connection. Annalogue channels are working ok.Ballymena area, any ideas?

Richard: In situations such as this, retuning is likely to cause more problems and doesn't solve anything. Unless it is known that the TV is tuned to the wrong frequency, then the tuning is OK.
I think that it's likely that the level of the signals to the TV have dropped, maybe due to atmospheric conditions (for example). Now you aren't going to know when they are back because your TV isn't tuned.
I suggest that you attempt to manually tune in any missing channels. Having got some tuned, then don't do another auto-tune scan because it will wipe them. Once you have some, you need to keep manually tuning to the channels (frequencies) of the missing ones.
For manual tuning, the channels used by Divis are:
Mux 1 - BBC One, BBC Two etc - Ch29
Mux 2 - UTV, C4 etc - Ch33
Mux A - ITV3, QVC etc - Ch23
Mux B - BBC Four, BBC Parliament etc - Ch26
Mux C - Pick TV, Dave etc - Ch48
Mux D - Yesterday, Film4 etc - Ch34

Thanks Dave, My father was in an electrical store in town and was told thesignal from Divis had been reduced or something.
I guess when it increase's again and if i do an auto scan they will appear. In mean time i will try manual scan
Thanks

Manual scan not working either, is saying signal quality none and level flicks from bar being nothing to ust on.

P.S. Might be a good idea to check all connections.

I've being trying to get an answer to this question from other places to no avail so I'm hoping someone can answer it here.
With London switching to digital in April 2012 and N Ireland not converting until October 2012, will N Ireland analogue viewers still be able to receive live broadcasts from London based TV studios and stadiums etc?
Presumably they will be transmitting fully digital signals so I'm wondering is there any implications regarding events like the Olympics etc.
Thanks.

M E Moore: The transmitters serving the London area will be switched to digital in April. That has nothing to do with Northern Ireland, even when the programming comes from London.
You haven't stumbled on some big secret to stop those in Northern Ireland from watching the Olympics!
