Cannot retune freeview on flat screen samsung

Hello Terri
Let's see if we can get you sorted out.
Make sure that you first of all have an aerial cable plugged into the TV.
Secondly make sure that you have it on a DTV (freeview channel) once you are at this stage press the MENU button on the remote. then go down to CHANNEL then across to Auto store and then follow the on screen messages.

That should be you all sorted out. If not then you may not be getting a strong enough signal from you aerial.

Hope all goes well. Please leave a thumbs up

Cheers
