The picture tube has a multi-colored hue around in a circular pattern around the edges/corners. It is blueish, yellow, green, and a little bit of pink. It just started this morning. We have changed nothing in the settings/channels/cable, etc. The color is not quite black and white, but certainly diminished. The picture quality is O.K. sharpness, contrast, brightness, etc. Just these colors. What are your recommendations?:confused:

Any Speakers or Magnets around? Magnetic fields?
