My TV has started playing with a wavy distortion. The distortion almost looks like a magnetic interference. It has this problem with everything unplugged. I have moved the set to different locations and different outlets, letting it sit for 5-10 minutes before using. When I turn down the contrast to about 20/100 and brightness to about
30/100 the distortion clears up. I have unplugged for 5-10 minutes and it has not helped. I have left unplugged over night and no help. Any ideas on what this problem might be? Thanks
