Hi, I was wondering if anyboby could help me

. I have the above mentioned sky+ box and I don't get a 'Lock-on' to the 'Dish input2'

, I have had the
Sky engineer out and he has confirmed it after checking all cables and connections, the symptoms were that I could not record and watch another channel, after checks it was confirmed that there is no input to number 2 dish connector, we swopped the dish cables and it was still no lock on to 'input 2' so there is evidently a fault in the 'box' which the sky people won't touch because I did NOT get the box from them, does anyone know a quick fix, or someone in the NW Cumbria area that repairs them and an approx. price of such a repair or even if there is a known spare that I would need ??
Thanks in advance, Barrie.
