Flickering screen in projectors can stem from various reasons. Here are some common causes:

- Blocked cooling fan: The cooling fan helps regulate the projector's temperature and ensure stable operation. Projector screen flickering may occur if the fan is obstructed by dust and cannot efficiently dissipate heat for the device.
- Internal component issues: If the Color Wheel is dusty or damaged, it can impact image reproduction as this component is responsible for color synthesis during display, potentially causing projector flickering. Additionally, another component, the Ballast, serves to supply power to the Mainboard. A faulty Ballast leading to unstable power can also affect the quality of the display on the screen.
