I have a full SWM system with a genie. Last year I took my H24 out to my shop and hooked it up my old 18" oval SD dish. Went into set-up changed to 01 18" oval and 02 Multiswitch. Then I could watch football in SD. Just tried to do that and all I get is Error 775, cannot communicate with dish a SWM error. Customer service said the box had reconfigured itself and would not work. I would have to get a new SD receiver added to my account. Does anyone anyone have any new suggestions? Thanks in advance for you help.
