I had the same problem...here's how I fixed it: The reason I got this code was because the box that is connected to the coax cable that comes into the house was unplugged. Find where the cable comes into your house (mine is in the basement)...you'll see it connected to some kind of splitter, which also has a power cable connected to it. Turns out mine was unplugged...I plugged it back in and voila! It worked! Keep in mind I am NOT referring to your actrual cable box...I'm referring to the splitter that is located wherever the cable is coming into your home. Good luck.
