Tuning Plasma Television

[axamaxa7]

I have just used Auto setup to retune my TV and have lost BBC1,2 and BBC News 24 as "Invalid Channels" in DVB mode.
I have fitted a brand new UHF Outdoor TV Antenna with a three way external Splitter Box after previously losing BBC1
The other TVs work perfectly.
Any solutions please

I`m no expert whatsoever, but we lost the BBC channels here as it was the 1st phase of the digital switch over. I re tuned the tv manualy.
