There is a picture and sound for about 2 minutes then the picture goes to a color vertical bar showing 3 colors, then a very loud awful sound starts up. The TV then shuts off by itself and starts up by itself and repeats this process. Sometimes there is no sound. I have unplugged the TV for 24 hours and still the same issue. It is only 1 year and 5 months old. I have a Monster power surge as well. Help pn50a650tf
