Sigh..... I hate it when this happens.... Last Monday, I got the second dish added so that I can watch Univision 19-Sacramento (wink wink smile). The channel came in fine on the two 301s. It got signed off. Went to my room and.... Univision 19 is all pixelated. The other channels that are available on 148 (ie International Promos, Good Samaritan) come in just fine. The signal strength for the transponder is around 93-95. Did the usual thing (front panel reset, pull the smart card, unplug the receiver) doesn't work. On the advice of Dish, tried the receiver on another outlet...same thing! Okay, Dish RMA's me another unit, installed it this morning, same thing happens. The advanced tech had me hook up a 301 to the outlet where I had the 501 hooked up... no problems. Huh? I've got a technician coming out Wednesday. Still, since knowledge is power, could this be a grounding problem, or what?
