I had sky plus installed a week ago. On first installation, I noticed a slight rippling of the picture, on lighter solid colours, but after about 30 mins it seemed to have dissapeared. overall the picture with sky plus has been far better than with standard sky. I got a new carpet fitted a couple of days ago and had to disconnect, then re-connect the box. Now the slight rippling is back again. Any suggestions. I have checked cables are tight and seemingly free from possible interference and have tried moving cables around, but to no avail. Any help greatly appreciated.
