I'm having some problems getting freeview satellite working. We've been in this house for about 2 years but I've never used the dish. My brother gave me his old sat box which was working fine and I thought I should be able to jsut plug it in and let it do it's thing. Unfortunately it keeps giving me a 'No (or bad) signal' message. Occasionally it'll manage to display TV1 and TV2 for a while but then they disapear too. I've crawled up into the roof and checked all the cables and all looks good. The signal was split into 2 using a splitter but I've removed that in order to try and track down where the signals gone missing.
Any suggestions on how to find what's wrong?
