Weird TV interference

[chameleon]

Hi, I have a new Sony KDL 32 v4000 LCD TV. I am running the cable box into it via a scart. When I'm watching a channel I am getting the TVs own freeview tuner ghosting through the av input picture. Anyone else experienced this? If I unplug the aerial I still get the ghost telling me the freeview channel cannot be found...
Any suggestions how to stop it?

Disconnect the aerial from the TV?

As I said, tried that but there is still a ghost saying it cant fing the freeview channel its on so there is still something there.
