I was getting 4 channels fine, 12-1 and 12-2, which I get get now, and 2 19 mexican channels that I don't watch. Why can't I get the 12-1 and 12-2 like I did? Did they change somehow? There's an antenna on the back over house behind me, does that do anything? ALSO, the light on the 9950 wild kept blinking, and now I can't get the 2 channels that I used to get, but get 2 channels that I didn't have before. WTH is the problem???????????????????
