Sorry but this is a long one!
History:
about 11 years ago I bought a Humax FOXSAT-HDR and at the time we lived on BUte off the west coast of Scotland. I set it up with the correct dish and everything worked fine.
We moved to lincolnshire 2 years ago so I bought a new dish/quad lnb and so on. I set up the freesat box and had no problems.
About 6 weeks ago I started to get a problem which was a complete loss of audio and video which would last for 2 to 10 seconds.
These are further details and what I have tried.
I had a Roku2 box connected and internet to them all via a Netgear Gigabyte switch both of which I disconnected.
I have also got a freeview box and a blueray player connected to the same Samsung TV. I get no dropout when viewing either the freeview box or watching a DVD.
So I thought I had proved it wasn't the T.V but to be sure I swapped the freeview and freesat to each other's HDMI input to the T.V but still the signal loss.
I then used a new HDMI cable for the freesat box but still no change.
I decided it was most likely the freesat box as it was by far the oldest part of the system. So I bought a Humax HDR-1100S.
Still no change.
I did a physical examination of the cables all the way to the dish and there appeared to be no damage.
I already had a cheap goodmans box in my conservatory but decided to put the old humax box in there. It worked fine and as I read that sometimes an LNB can fail due to overheating I bought a new quad LNB.
Still no change. In fact I set the old box up to display the signal strength/quality and turned the sound up on the system in my living room and watched the signal display on the old box. When the audio/video on the living room box dropped out the old one was rock solid.
The cables at the dish end had been bound with self annealing tape and as I disconnected them from the old LNB I could see they were still looking brand new with no rusting at all.
I could replace all the cable but first I thought I would ask you guys. Any idea if there is anything else I can try?
