So I think this has pretty much started today/tonight because I am pretty sure I watched ESPN2 yesterday. Now it says "complete signal loss." Also says it on TLC and other channels. What's going on?
There's lots of things that could have happened. Corroded connectors, dish hit by bird, or big wind gust. Something on dish may of already been loose or bent and gets worse every time the wind blows. This is something that can take over a year until it's bad enough to cause problems. You're going to need to setup a tech visit.
