i got a new tv to put in my room. the dvr is hooked up to my tv and my parents got their sattelite from a coax cable that plugged into their crt tv. i gave them my old westinghouse tonight and tried getting the sattelite to work on it but all i kept getting was a blank screen. i cant get the westinghouse to find the signal. every channel i go to it says "channel not found" and under that it says "tuner" in the top left corner. i dont know what to do or how to fix this. i dont want to pay someone $90 to come out here and do something i can do myself. can the westinghouse lcd tv not pick up sattelite/hd through a coax cable cord?
