Maxview satellite system

Hello all, We have an Auto Sleeper Cotswold with a Maxview manual satellite tv system. Just can't get it to work. The tv - an Avtex plays DVD's  with no problem. We have had the 'box' moved from the tv cupboard to the one above as it was rubbing the tv screen, and had a satellite finder installed as well. Now when we turn on the box lights up green but goes red when the satellite finder is turned on. We know the theory of finding North raising the dish and then turning it south etc. Has anyone got any suggestions before the whole system gets changed?

Just a thought, does your tv select (usually scart or hdmi input automatically ? or do you have to select it manually like ours.
