I am new at the satellite world so please go easy on me if I ask some basic questions. Currently we are using a 2 - 301 receivers, have a dp34 switch. We only see 1 satellite - 119. Trying to replace 1 of the 301 receivers with a 811. When I plug it in it goes thru the searching for satellite screen and then comes up looking for video 1 or video 2 input, also the satellite light on the receiver is not lit. Don't get any channels. Looking for suggestions. Also some basic education - do you need to see all the satelllites?
