Hi Rooibos,
We understand that freezing can be an unbearable nuisance, and we truly apologize for that. I do not detect any known issues or outages in the area if Orange County. Freezing generally indicates that a signal issue is present somewhere. Can you please check to ensure that all cables are secured nice and tight and free of damage? Also, if you have a splitter, I would recommend removing it and running the cable directly to the wall. If this resolves the picture tiling and freezing, then it could be an issue with the splitter. Resetting the equipment would be a temporary fix. -Kevin M. Cox Support Forum Moderator
