1. Does the screen display 'no signal'? please check if the input source mode of the projector has been selected correctly.
For example, if the device and projector are connected using an HDMI cable, the signal source must select an HDMI 1 or HDMI 2 channel for projection. If another channel is selected, the signal will not be displayed
2. Please confirm whether all cables are connected to the projector correctly and stably.
3. When there is no device connected and no signal displayed, please press the 'Menu' button.
4. If it still doesn't work, it is recommended to unplug the power cord directly, turn it on again, and then check if the image can be displayed normally;
