Troubleshooting if the Mi Smart Projector is turning off automatically after being turned on, please refer to the following steps:
1. Make sure the power cable is firmly plugged into both the projector and the outlet. Loose connections can cause shutdowns;
2. Ensure any automatic sleep or power-saving modes are turned off in the projector's settings;
3. Keep the projector well-ventilated and free of dust. Overheating can trigger automatic shutdowns. Clean the vents and place the projector on a flat surface;
4. Check for any available firmware updates for the projector. Sometimes, software updates include fixes for issues like automatic shutdown;
5. If the issue persists, consider performing a factory reset on the projector. This resets all settings to default, so back up any important data before proceeding;
6. If the issue persists, contact your local after-sales for further assistance regarding this issue.
