Video and data projection
are there colored dots in my projected image?
specks on the LCD inside an LCD projector will appear as colored
dots in the projected image. This is a confusing situation, since
dead pixels look about the same and require replacing the LCD
panel to eliminate them (very expensive). Dust on the LCD can
be labor intensive to fix, but it's a comparatively inexpensive
repair. You can see why it is important to use a service center
you know and can trust. By the way, to minimize dust accumulating
on your LCD panels in your projector, clean the projectors filters
on a regular basis.
