Thanks. I'll go through the checklist and let you know how I get on.

Thanks to all, excellent help. I've been through everything suggested plus digging out an old Sky+ and a Sky HD box, both worked OK. As a last resort I checked out capacitor C848, which I'd replaced some time ago, only to find that the joint I'd soldered to the previous cap wire was not in tact. Fortunately I had another cap so to be sure removed the motherboard, drilled the old wire and solder out then soldered the new capacitor to the underside as per the original. Thanks to Abu, I did go through everything you suggested and learnt a lot on the way that I didn't know before. To be sure I reset the ABM and XML file, manually tuned B to every frequency, and restarted the GUI. Everything is now working apart from a "tune failed" on France 24 & S4C, which I will try and fix but if not can live with.

Thanks again to all who offered support.
