I'm wondering if anyone here has seen something like this. I've been living outside my house while some remodeling has been going on. On Feb 15, I re-routed the coax lines from the satellite to the wall jack in my living room (disconnecting then reconnecting the same connection points). On Feb 19, the drywall guy put up drywall on the other side of the wall from the wall jacks, and did mud/sanding on Feb 20. Sometime on Feb 20, I stopped getting every channel except local channels and, like, Nickelodeon. (I can tell this from Recording history). The error message on all my channels such as HBO, COMC, etc. is no signal from Satellite 2 (771). When I check signal strength, only 101-degrees shows anything at all. All the other locations -- nothing. I did some troubleshooting with a phone tech on Saturday. - Hard Reset - Tighten connections - Visit all sorts of 9xxx test channels The tech then insisted that I had some sort of power booster somewhere on the coax line. Something that the coax line ran through that was also plugged into power. Since 2006 when I got HD, there has never been such a thing, and since I recently re-routed all the coax, I know every inch of the coax line. There are only two, small rectangular boxes (non powered) very close to the receiver -- coax in, coax out. I have subsequently tried: - unplugging and then replugging all coax connections: at the receiver, at the two small boxes, at the wall plate, behind the wall plate, and at the dish. - inspecting the cable that is within the walls (pulling the slack in each direction) - re-crimping the end on the wall jack for the line for Sat 2 since the crimp job was squished (but probably has been that way since 2006). I just don't get it. 1) Why do I get some channels and not others? 2) What is the deal with this power device I've never had? 3) If the line is free of (visible) defects, why did it fail on Feb 20? 4) Any ideas how I might solve this? Thanks to anyone who understands this better than I do. I just have some logic (it used to work) and a knowledge of the physical coax line.
