I recently installed a Direct 3lnb dish at my vacation home in Niagara Falls. I brought one of my receivers from Orlando. I show 91% signal strength on Sat A (101), but no signal at all on 110 or 119. I get no reception at all when i hook up a tv. the on screen test recognizes the access card and says i have signal, but still no picture. hope you can help? thanks, Jim
