Thats caused by a bad optical block. The cost of that repair will almost always be greater than replacing the TV.Thats a very common issue with alot of Sony DLP models which suffered that optical block issue with the blobs of color usually blue or green

SOURCE: bright blue spots on lower right corner of Sony Grand WEGA KF50WE610 50 in. Rear projection tv

The spots are from dust in the optical assy. It would need to be replaced because the only way to fix the part would be to disasemble it in a dust free room.

Blue spot on screen


  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
