I have a slimline 3 dish, a 6-8 switch, a hr23-700 receiver and b band converters. when I go to satellite setup and choose slimline3 dish, multiswitch it still tells me not to install b band converters, with or without them installed i receive all the channels but when i switch to an hd channel it says searching for satellite signal on 2, any ideas??????? Any help would be GREATLY appreciated! Thank you in advance.
