My picture has a black spot in the centre covering 50% of the image. Replaced the lamp. Still the same.
Optoma EP7155
My Optoma EP 7155 DLP video projector works great for awhile, then suddenly the images or video turn shades of magenta. The image on my computer is normal-colored. The projector has not been changed from default color settings - at mid-range. When I use it the next day, it\'s fine. Any ideas?
