  1. First, look for the source of the problem. Large speakers, especially older ones, are the most common offenders. Notice the position of the blue spot on the screen (left, right, upper, lower, etc.) for an indication of which direction the magnetic field is coming from.
  2. If you think you have determined the source of the magnetic field, try moving the object away from the television screen. If this does not work, continue looking for other potential causes.
  3. f you are unable to determine what is causing the magnetic field, try moving the television. Sometimes magnetic interference can come from a neighbor's equipment, especially in apartments and condos. Moving the television to another part of the room, away from shared walls, may help.
  4. If none of these techniques succeeds in removing or improving the appearance of the blue spot, try to find if their is any demagnetizing coil button available in front of the TV panel , it may be symbol like magnet and a diagonal line on it

Blue Noise, left side of TV


I have the same problem -- had a Best Buy technician out 4 times so far, replaced 2 parts, adjusted the voltage, etc., but still have the same problem -- looks like there may be no solution other than replacing the TV, which is an expensive proposition considering that mine is about 18 months old.
