I have noticed three transparent bands that appear on the screen from time to time, mostly during brighter scenes. One is seen horizontally across the center and the other two are vertical. Is there something wrong with my TV? I was watching Dances with Wolves last night and whenever the blue sky is in the movie I can see the lines. It is very distracting. I tried different dvd players and even different cables but nothing helps. Any suggestions? I doubt Toshiba will be of much help.
