Strange problem opening Sly Italia

[laserquest]

SkySports HD channels are showing as 0 signal, despite the fact i can receive SD no problem. I've checked the frequencies for the channels on lyngsat. I've tried using catseye and mrmister channel lists but nothing seems to happen. any ideas? Other HD's show a signal no problem at all.

Edit: Tune failed keeps appearing too. The tuning setup is positioner USALS on Tuner A.

Best thing to do is run a full re-scan of Hotbird.
