He has Lewy Body, and his ability to work things like the telephone, computer, and TV is impaired. TV is his life! He doesn't remember what's on what channel, and if he does know a channel, can't figure out how to key it in. He sits in his chair and uses the arrow on the remote from one channel to the next, but seldom stops to watch a show. He will play with the remote until he gets someplace where he needs to make a choice, and then calls me to fix it. Today he did something to completely lose the picture, and anything I tried to do to fix it didn't work. I had to call support. I know it will only get worse. Any suggestions?
