Hi,

I have a greeny yellow haze like a badly cut film aperture on the top left corner of the screen. It is about 6 inches tall and protrudes about 2 metres inwards towards the centre and disappears. Someone suggested that the Christie 2000ZX mirror my have shifted and is out of alignment.

Cheers,

david.

That effect would also be a problem at the integrator rod (I am not sure about the Christie line). A damaged element in the integrator rod usually caused by a bad UV filter can cause that effect. The other case which is worse is that you have permanent damage on the DMD units due to overflowing the light.
