FINALLY we had a good tech come out, he had recently moved down here form a big city and wasn't an uneducated fool like our current people were... what happened he said was trash in the lines, and yes he dumbed it down for me. lol

There was 1) Trash in the lines, the waterproof seals they had put on them had basically sprung a leak and water and dust particles and other things had gotten in there between the connections and was trashing up the lines.

Next they had to replace their lines that came to our house, they were so old they were beginning to fray, so he replaced that line and everything worked perfect.

All the previous guys could ever do was just tell us it was on our gear, which I knew better because it was all new, but this guy went right to the problem and had it fixed within an hour.

Tell him to go to the connections OUTSIDE your house if nothing else works and see if that will help.
