| Problem | Possible Cause | Solution |
|---|---|---|
| No image displayed | Power cable disconnected, incorrect input source, device not powered on. | Check power connections, select correct input source (HDMI 1/2, AV), ensure connected device is on. |
| Blurred image | Out of focus, projector moved. | The AI Movin System should auto-focus. If not, check for obstructions or manually adjust focus if available in settings. |
| Distorted image (trapezoid shape) | Incorrect projection angle. | The AI Movin System should auto-correct keystone. Ensure the projector is placed as squarely as possible to the screen. |
| No sound | Volume too low, external audio device not connected/paired, incorrect audio output selected. | Increase volume, check Bluetooth connection for external speakers, ensure internal speakers are selected if no external audio is desired. |
| Cannot connect to Wi-Fi | Incorrect password, out of range, network issue. | Verify Wi-Fi password, move projector closer to router, try a wired LAN connection. |
