My in-laws just upgraded to the 5lnb dish and can not get a signal on the odd transponders on 103c. Installer tried 3 different HD boxes( 2-HR21, 1H210, 5 different BBC's, 2 different sets of lnb's, and 2 different multiswitches, and still could not get them to come in. They have high 90's signal strengths on all other transponders that they can get. Anyone have any suggestions on what else it could be. Installer gave up and said they were gonna send someone else out but noone has come. thanks.
