About a month ago we had a storm and received 5 inches of rain in two days. I went to bed with a perfect picture on my three Samsung TVs. The next morning I had lost some HD resolution on all TVs. Direct TV technicians have been out several times. They have run new cables, realigned the satellite and I have a new receiver box. If I go to Direct TV channel 125, which is broadcast in 1080p, I get full HD resolution. If I rent a movie from Direct TV Cinema that is in 1080p I get full HD resolution. But when I watch any of the regular HD channels, which are broadcast in 1080i or 720p, I do not receive full HD resolution. It is the same on all three TVs. It's like 1080p is working but 1080i and 720p is not. Direct TV says they have done all they can do and that it must be my TVs. I don't believe all 3 of my TVs went out at the same time. Don't know what to do next. Need help!!!
