My x1 Box was knocked off due to lightning. Everything came back on. But the box is no longer sending a signal to the tv. Even changed tvs to see if it was the tv. No luck. This is the 2nd time this particular type of box (xg2) has done this. The previous boxes didn't do this. I have it plug into a surge protector already. But it seems particularly sensitive and unfixable. I get tired of taking it back to Comcast. is there anything I can do to fix and keep from happening in future?
