I have found the solution at last :)
Put the TV in standby and press these buttons in order
Info, Menu, Mute and Power on.
You will then see a hidden menu, on line 12 select reset
Bingo :)

SOURCE: DTV locked on ITV1

do a reset in the service menu the turn the tv off and press..

info>menu>mute>power on

and go to the reset option. don't mess with any other setting in this engineer menu.

The most likely problem is the aerial system you are using in your new location. It could be either the position of the aerial needs to be adjusted or the cable coming from the aerial has a problem, check the end connector that goes into the Tv to make sure it is wired correctly. Also check with your new neighbours to find out what quality of reception they have, it's possible you may in a "weak" zone for picking up a freeview signal.

SOURCE: no digital yet tried to retune but greyed out.

Just got through to Samsung support. Turns out the freeview card had frozen and needed a reset. To do this put tv on standby. then press in serries these buttons on the remote: 'info' 'menu' 'mute' 'power' TV will then turn on with a default screen. Press 'arrow down' button untill you reach option 12 'reset' . then push the 'right arrow' and tv will reset and start in plug and play mode and commence a scan when you've set the time. Just retuned mine and its back to normal. Hoorah!!! :-)
