Problems with TV - DirecTV

When I come home in the evenings, my TV is on with static, like when cable is off and TV is still on. When I watch a show that has been recorded on DVR, it will cut out sometimes with this same type of static for several seconds, then return to program. I do not like having the TV running for who knows how long during the day. I usually get home after 5:00 pm. What do I need to do, or does a technichian need to come check it out? Have 2 TVs and this only happens with the one in the living room.
