my dish network controller (black one, not silver)has been working for a month and then it started not working and sometimes if i blow on the little key at the bottom that has a #2 on it it starts working until next time i turn it on.but that's not the problem because now it does not work at all and i have a feeling that it has to do with the #2 key because my tv turns on and the volume goes up and down but nothing else works on it
