I have had a magic eye fitted into 2 rooms in my house early this year. At first the picture was great but it now seems to have faint lines running accross and i cant seem to workout why. The picture is fine on my main TV which is were the box is connected but the two connected to magic eyes are very grainy. I have swapped aerial cables,turned off the box etc but nothing changes.

Try altering the output RF channel on the Sky box - not forgetting to re-tune the TVs.
If you're not sure how to do it see here under Installer setup
