thats a common symptom for that model which is usually related to the optical block. Very exspensive repair. Check with a sony authorized repair center as Sony has recognized the problem and offer assistance with certain models yours may be one of the ones affected.

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.
