I am Using dishtv since last two years.My Dish antenna is align properly .Now the problem is My stb starts with red light blinking and afterwards it becomes Red and when i again on from the remote it shows 301 Signal not found.I Had called CC they told u have to upgrade the software of stb .after few days it became ok.Now again the same problem .This problem started when Dishtv started showing the ad in which they upgrade our stb when it is off postion(red) .I think during upgrade they spoiled by stb.What to do.Is any one else facing the same problem.?
