      Tyler HooperAug 14, 2025
      If your LG Home Theater System DVD or CD won't play, first insert a disc if none is currently inserted. Ensure that the disc is playable by checking the disc type, color system, and regional code. Make sure the disc is inserted correctly with the label side facing upwards. If a menu is open on the screen, press SETUP to close it. Lastly, check if a parental lock is enabled, and if so, enter the password or adjust the rating level.

    Why is my LG Home Theater System making a humming noise?

      Aaron MezaAug 22, 2025
      If you're experiencing humming noises from your LG Home Theater System while playing a DVD or CD, try cleaning the disc with a soft cloth using outward strokes. Additionally, ensure that the DVD receiver is not too close to the TV, as this can cause feedback. Move the DVD receiver and other audio components further away from the TV.
