On 1/8/2010, I had my Directv system upgraded. I replaced my 5-LNB Dish (non-slimline), HR20, HR10, and H10 with 3 HR23s, a 3-LNB Slimline and SWM-8. Everything was professionally installed by Directv (well their contractor). Today, I come home and find that all 3 receivers are complaining about not getting any guide data. I check and no channels work, and I have no signal at all (0 on the signal strength). The dish is still standing, it didn't fall over or anything, everything is connected and powered on including the SWM Power Inserter. Any suggestions on what might be wrong? I called the installer who is closed right now -- and I know Directv will simply schedule another appointment for someone to come out and look at it since I have no signal they can't help me. I've already tried: - Resetting all 3 receivers (RBR and Soft-Reset through the Menus, and unplugging / plugging back in). - Unplugging the SWM Power Inserter and plugging back in. We did get rain last night with a bit of wind, and the weather is notably warmer today than it has been lately (was in the 60's today and previously it had been in the 30-40's). It currently is raining, but it was sunny this afternoon, so I would have assumed the guide data would have been available if it had to do with weather. I also would assume that I'd get a signal strength greater than 0 even if it was raining.
