Question about Vivitek Office Equipment & Supplies
The problem started with a few black and white spots and continues to spread everytime i use the projector. i had the projector 3 years but may have used a dozen times for less than 1 hour of usage each time
The DLP Chip is failing .The DLP or Digital Light Projection Chip contains up to 8 million tiny microscopic mirrors that tilt to project a digital image onto the screen. These mirrors are failing causing light and dark spots to appear.Unfortunately fixing this projector is probably going to cost more than buying a new one. Hope this helps.

there are light filters behind each lcd panel that determine the color of light going through it. because of excessive heat and dust, the filter tends to burn and cause discoloration in the image. if the image is bluish (cyan), the red filter is burning. if it's yellow, the blue is burning. if it's purplish (magenta), the green is burning. the filters will need to be replaced. unfortunately, many companies don't sell individual parts of the optical engine, so the entire engine might need to be replaced.
