I'm about to Terminate my contract with Sky and set up Freeview which is built in to my t.v.(Samsung LE40R74BDXIXEU).
The problem I have is that having Sky connected I've not turned in any of the terestial channels. What I'm confused about is how to set up my freeview up, I've plugged the arial into the t.v. but kind of got lost with th set up and looking thru the manual is a bit confusing too. So if anyone can help that would be great!

Make sure you have an aerial plugged in to the TV.
Press Menu and arrow down to Channel and press Enter.
On the Country line press Enter and select your Country by using the up/down arrow ...UK in your case and Enter.
Arrow down to Auto-Store and press Enter...Press Enter again and an on-screen bargraph will appear as the channels are tuned.
At the end press the D-Menu button and repeat to auto-tune the digital Freeview channels.

Many thanks for that John!
