Replacement receiver not working
I just received a replacement receiver from DirectTV (model H24-700). The previous receiver (model H44-100) had stopped working. I hooked up the replacement unit exactly as the original unit. Error message: cannot detect SWM. I do not see anything that looks like a SWM. Did they send me the wrong type of receiver? Also, the manufacture date on my old one was 2015; the replacement is 2011. I find this very strange and don’t know what to do. I have contacted the online tech people. They are stumped and want to send out a technician. Is there a quicker fix for this issue?
