By this do you mean that you have tried anoter digibox on your cable and dish? If so then it looks like your Grundig has curled up its toes!have tested with digibox and sat dish and cable seems fine.
Funny you mention that,I know someone with the same problem with same box.Problem started 3/4 days ago,with break up on known strong channels like sky sports and news(on a 2.4m dish where the signal is excellent).Swapped with a working power supply but same result.Our technician was going to swap tuners today but heard nothing from him so maybe bad news.I dont think its a z-if tuner though.ntoon said:im having problems with the grundig gds2000 skydigibox. it just displays no sat signal being received. have tested with digibox and sat dish and cable seems fine.
any help please?
