Here's an interesting problem I just resolved.
I have 2 dishes - a Dish500 at 110/119 and another Dish500 at 129. Last Sunday (2/14), I noticed that the 129 channels were coming in and out and by the end of the day they were all out. Last summer, I replaced the LNB on the 110/119 dish because it was behaving the same way. So yesterday I got on the roof to check it out. What I determined was that the LNB wasn't screwed down all that well and would wobble a bit when the breeze hit it. Apparently that slight wobble created a sympathic vibration that caused the coax to become unscrewed from the LNB - probably over a period of months.
Easy fix and I was thankful it wasn't something that would cost me anything, but it was certainly surprising.
Just thought I'd post this for future edification.
