I have the whole home setup with the HR20 in one room and HR21 in the other. Recently, I disconnected the receiver in my bedroom where the swm and network adapter are located. When I reconnected everything in the bedroom, I got the 771A error so I checked the connections again and everything seemed to work without changing anything. A few days later, I'm getting the 771A error again on both TVs. I called Dtv and they walked me through powering everything down by unplugging and we couldn't get it fixed. The swm does have a solid green light on it. The white "deca" box in the bedroom does not have any lights on it but they come on briefly when I unplug the receiver and plug it back in but they go out again. I've tried power cycling the swm, then the network adapter (or whatever it's called) then the receiver but that didn't work. I've tried combinations of power cycling different components. I tried bypassing the network adapter thing (for the VoD) and that didn't work either. Still 771a on both TVs and I only have the local playlist for each DVR. They cannot send a tech out until Saturday, 6 days from when I called. I am disappointed to say the least that it is going to take so long to restore service and would welcome any suggestions for something I could possible do to fix the issue. Thanks in advance.
