Blemish spot on projected image, what is causing it?

I have a Sharp [model XG-NV1U] that work very well except for


a yellowish spot that is projected at bottom of the screen shot


in the middle section. It is only visible during dark scenes of a movie. I tried every where to get an answer on what is causing this and no one knows. Is it the bulb or something in the electronics? Thanks in advance.Blemish spot on projected image, what is causing it?
I would almost say it is something on the bulb or it is miss aligned just enough to cause light to reflect from somewhere and shine right at that spot. Since it is a notebook projector, things are alittle tight and if you move it from time to time things can move inside the unit too. But it really does sound like a reflection issue to me.
