  David HigginsJul 29, 2025
  If your LG Projector remote control isn't working, there might be a few reasons. First, if you have a lamp with an electronic stabilizer or a three-wavelength lamp installed, this could interfere with the remote's function. Try replacing it with an international standard product. Also, make sure there are no obstacles blocking the path between the remote and the projector. Ensure the batteries are correctly installed, paying attention to the polarities (+, -). If that doesn't work, replace both batteries with new ones.

  Your LG Projector might be turning off suddenly due to several reasons. Check if the [Sleep Timer], [Auto Off], or [Auto Power Off] settings are enabled. Also, consider whether external devices are influencing the projector's operation. The auto-off function may have been activated. This product is equipped with an auto-off function that automatically turns the product off when no signal is present or when the remote control has not been pressed, depending on the settings for the auto-off function.

Why does my LG CineBeam HU715QW make noise?

  Your LG Projector might be making noise for a couple of reasons. It could be electrical noise, which is a small sound from the high-speed switching circuit supplying current, and this can vary between products. Alternatively, it could be the fan, which increases or decreases speed to maintain the projector's internal temperature, depending on the room's temperature.
