Hi:

The problem here is the one of the miniature LCD screens in the unit is faulty, in this case its the blue one. There are three of them inside the unit RED<GRN<BLUE.

Blue spot on screen


there are light filters at each of the 3 lcd panels in the optical engine with a coating on them that determine the color. one of them (most likely the blue) is burnt from the heat and needs replacement. it could also be the fly-eye lens (whick evenly distribute the light) has burned as well. either way, it's very involved to replace, if you can get the parts. it's easier to have it sent in to get repaired.

Large dot in the middle of the projected display


there is a burned-in spot on the polerizer light filter for the blue lcd. it makes sure the light is blue coming through, that's why it is black on a blue screen, and yellow when the red and green are the only light showing through. it needs to be replaced. pat # PFiLW0213CEZZ.

Blue spots on screen


Obviously this is not the first lamp you have replaced in you projector. These are great projectors however, the LCD panels expire quite quickly. You will find that the spots are related to the LCD panels needing to be replaced. This is not an inexpensive maintainence solution as the panels cost about $1500 each.
