A couple of weeks back we had some rain over the course of a few days. My sky signal went from getting some interference to no signal at all during this period and how I'm trying to figure it out. I had a spare old sky box, so I hooked it up and it was showing the same no signal message. There is a two feeds going into the box so I think it is unlikely a cable problem and I have done a quick visual inspection of the cable and it seems fine. From what I've read trees can get in the way of the dish and yes there are tree close by but I don't think this could of happened in this short space of time. I also can't see it being a dish mis-alignment as if I try to move my dish in any direction, it won't budge. That lead me to thinking it must be the lnb, so I brought a replacement and that didn't seem to make any difference either. I've tried adjusting the skew settings on it with no luck and now I'm out of ideas. Being short of cash as always I'm trying to avoid calling out an engineer, so I can learn about these things the hard way! Much more fun!
