Let me start by saying that I don't know much about the tech surrounding my satellite, so go easy on me. 
I have 2 receivers, one is a DVR that says 625 on the front, the other is smaller (not a DVR) and doesn't say any model numbers on it that I saw.
My landlord recently re-shingled my roof and after he put the dish back I got very poor signal. I would get the lower (local) channels alright, but anything past 100 was hit-or-miss. I told him about the problems and his response was basically "I marked where it was and put it back on where I found it". I tried messing with the dish earlier today (bad idea) and now that hit-or-miss signal turned into no signal at all. I tried following the numbers listed in "Point Dish" to align the dish, but I got nothing. I ran a switch test and I got "Reception Error". So I have nothing right now.
I'm not sure what to do without messing anything up anymore. What can I do to try to get my signal back? I didn't want to have to call Dish Network if I didn't have to.
