This afternoon while watching Sunday ticket, i hit the down arrow key to enable DoublePlay and as soon as I did, the screen with Grey. I ended up having to reboot and when I did, I received a 771a searching for signal error. I have 2 receivers and this is only happening in the Living Room. Master Bedroom is fine. I had never heard of the error, I went through rebooting a bunch of times and finally called Cust Service. First thing she had me do was turn off the power adapter for the satellite (I think that's what it's called). Then reboot. The reboot did not work. After about 20 minutes, the CSR stated that b/c i'd had more than 3 771 errors in the past, that my call woudl be handled by a manager who would call within 2 hrs to work with me on it. They never called. I then came on here and remembered about the diagnostics screen at bootup. I went through a number of HD tests and they all passed. I then noticed the 3490 SWM Test -- and it passed. I allowed the reboot to continue and everything seemed to be working fine. Fast forward about 2 hrs. Same issue. I try rebooting etc... Nothing works. I go into the diagnostic screens, run the SWM test again and now I get a: FAIL - 0x47 error. Any ideas as to what could be wrong? i checked all the connections and everything seems to be fine. By the way, I never had SWM before, but about 2 weeks ago a technician was out to check on the 771 errors i was getting and they switched out some cables and added SWM.
