The white spots you are seeing are a result of dust or dirt in the light asm. Mits knows about this as a problem. The inside chamber of the tv needs to be cleaned. If your tv is in warranty they will come to your home and fix it. If not it is very easy to damage the tv by trying yourself, start with cleaning out the chamber that the bulb is in, use compressed air to blow out dust and dirt, them on the sides of the tv are round flaps that will need to be removed and this will go into the main mirror chamber, be careful but blow out any dust or dirt you see on the mirror. I would have a repair tech handel this unless you are skilled in this area.

SOURCE: We are having white dots
That means you need to replace the Optical Unit Block/Light Engine.Dmd board has been known to cause this also, but most of the companys replace Dmd and optical unit.
