  Your LG Projector might be turning off suddenly due to a few reasons. Check if the [Sleep Timer], [Auto Off], or [Auto Power Off] settings are enabled. Also, check if external devices are operating together, as this might affect the power. The auto-off function could also be activated; this feature automatically turns off the projector if there's no signal or remote control input, depending on the settings.

  If your LG Projector remote control isn't working, there might be a few reasons. A lamp with an electronic stabilizer or a three-wavelength lamp near the projector could interfere with the remote's signal; if this is the case, replace the interfering lamp with an international standard product. Also, make sure there are no obstructions between the remote and the projector. Ensure the batteries are correctly installed, paying attention to the polarities (+, -), and try replacing both batteries with new ones.

  Your LG Projector might be making noise for a couple of reasons, and these noises are normal. Electrical noise can occur due to the operation of the high-speed switching circuit, with the sound varying by product. Also, the fan sound may increase or decrease to maintain the internal temperature at an appropriate level, depending on the ambient temperature.
