Satellite Feed - twin connection to single - help please

InDebted2U_2

I used to have Sky, so I have a twin connection coming off my satellite dish. I have a Sony Bravia Freesat TV with a single connection. It's worked fine with just one of the twin cables plugged into the TV, until recently. Reception has become terrible, and today the TV completely lost signal or the ability to operate the menus, etc. I got the TV working again using a hard reset, but there's still an issue with the Freesat reception. Is there a way to combine the twin feeds into one, or is this even likely to be helpful?

 Try the other cable, either should work as they are effectively two separate signals. There is no point in combining the two feeds, they wont add the signal from each together

If both the cables are causeing problems then it's possible that A) the telly is faulty, the satellite dish has moved, C) the LNB at the front of the dish is faulty or D) the cables or connectors have been damaged. has anyone been fiddling with the wiring. You could try reterminating the connectors

The first thing to have a look at is if the dish is still pointing where it should be, it is unlikely if the box was happy with a single feed before that it would suddenly need a dual feed now, either that or look for cable damage which might mean water has got inside the cable.

 I have freesat running from syk like you, and it was a problem with the dish, friend of a friend who works for syk fitted a new dish for a few quid.

Swap the cables over.  If the fault follows its usually an LNB fault.

Satellite signal issues are usually caused by one of four main things - tree/obstacle in the way, bad weather, LNB/cable fault, (rarely) broadcasting fault.  Nothing else to go wrong.  The dish itself is just a lump of aluminium metal, there's nothing to go wrong with it, unless its been up many years and is rusting away.

The last one I looked at for a friend with bad reception symptoms it was the LNB on the dish which was kebbabed
Water ingress I'd guess

The two most common "faults" on satellite TV are LNB issue/failre or physical obstacles in the way (trees, buildings, scaffolding, etc - also things like thunderstorms, heavy snow, a major downpour and sometimes fog).  If your signal works wonderfully in the winter but goes to pot in the summer its almost always caused by a whopping great deciduous tree in the way.  No difference between evergreens and deciduous in this department, both will block satellite signals.

Modern LNBs have covers on them I believe to protect them, but silicon grease also helps as a seal, otherwise it'll be toast again in five years.  Water corrodes connections, simple as.  You can't stop it raining and you can't put a cover over the whole dish, otherwise there is no signal.  Water will hit the LNB at some point.
