White spots on a projector screen are most commonly caused by DMD chip mirror failure in DLP projectors. The spots usually start small and increase over time, and the correct repair is diagnosis followed by DMD chip replacement if the chip is confirmed faulty.
Why white spots appear
Many DLP projectors use a DMD chip with thousands of tiny mirrors. When some mirrors get stuck, they can show as white dots, black dots or sparkling pixels on the projected image.
- White dots or black dots on screen
- Sparkling points in dark scenes
- Dots increase over weeks or months
- Image still appears but looks distracting
- Common in many DLP projector models
Can cleaning remove white spots?
Cleaning may help dust shadows or blurry patches, but true white dots from a failed DMD chip do not disappear with lens cleaning. A technician should confirm whether the issue is dust, optical damage or DMD failure.
Local repair advice
