ViewSonic Projector
If you see stuck or twinkling pixels on the projected image of your ViewSonic projector, the DMD chip of your projector may be defective.
These pixels can show up as bright, dark, or twinkling points. They look similar to pixel defects on LCD displays.
This problem cannot be fixed by yourself and must be sent in for service. If your ViewSonic projector is within the warranty, you can contact ViewSonic Customer Care for support and repair.
