EU46D8000 help tuning in

[Thug]

I have just moved my Samsung EU46D8000 to the kitchen/family room due to an upgrade in the living room and having a little trouble.

I have only ever used it through Sky for terrestrial and never tuned it in to digital DTV before, but now I have to due to not having sky in the kitchen.
When it tunes in to DTV it only finds 110 digital channels and no HD at all. I have tried to update the firmware which says I have the newest installed.
The channel list shows 4Music as channel 1 where I am sure it should be BBC1 like the one I took out.
The 2015 Samsung (32") I took out of the kitchen and put in the bedroom found far more including HD whilst in the kitchen.

Any ideas?

Tried a few things I read on the net, including rescan with the arial lead out, then again with it in, which didn't work.
Tried manual scanning channel 31 which should zero reception (all others show very high reception quality).
Any ideas?
