Why does my LG CineBeam HU915QE Projector power turn off suddenly?
The LG Projector might be turning off suddenly because the [Sleep Timer], [Auto Off], or [Auto Power Off] is set. Also, check if external devices are operating together, or the auto-off function may have been activated due to no signal or remote control use.
What to do if LG Projector remote control is not working?
