fragmented/frozen picture - DirecTV

My TV's are freezing up w/fragmented colored squares all over the screen. I had a technician out at the house and he replaced my power box in the garage, changed the part of the dish that they do V channels, NFL, and many UFC PPV's but this is a PIA, now will have miss work if I can get another tech out here

This question, "fragmented/frozen picture," is about DirecTV channels, programming, equipment, and sports.
