Hello all...I just hooked got a new Insignia flatscreen 26" TV to replace my old old TV that was the second TV hooked up to our dish. And I hooked the coaxial cable and everything up to this new TV, and now I can't seem to find out how to watch my dish. I've tried channels 3, 4, 60, and 73...I've tried every input. But I can't find it. Thank you for all your help!!
