HI, I might seem dumb but please can someone help. I bought a second hand digibox (Grundig) from ebay. I plugged it in to my existing system (is for my caravan and I have a seperate dish for that)to test it and I get a message on the screen saying "no satellite signal being received". I go into set up and it tells me I do have a signal ie the bar is full of grey (as I must have for my existing box to work) but all the other fields are at "0000" or no grey filling the bar or "not locked" . I try my old box and its fine. Ive tried it with my card but it does not even recongnise its there! The lovely chap I bought it of is a con merchant as I have tried to contact him for two weeks (be aware of seller "mainsyuk" on ebay) and he seems to have disapeared up his own ....! I have an signal amplifier and have tried using that and it makes no difference, Ive tried too many things to list. Please help me if you can, many thanks, Kangacats.
