      Danny CooperAug 14, 2025
      If you hear a humming noise while playing a DVD or CD on your LG Home Theater System, the disc may be dirty. Clean it with a soft cloth, using outward strokes. Alternatively, the DVD receiver might be too close to the TV, causing feedback. Try moving the DVD receiver and other audio components further away from the TV.

    • S
      Steven MunozAug 21, 2025
      If your LG Home Theater System isn't playing DVDs or CDs, first, make sure a disc is actually inserted and that it's a playable disc (check the disc type, colour system, and regional code). Ensure the disc is placed correctly with the label side up. If a menu is open, press SETUP to close it. Also, check if a parental lock is enabled, and if so, enter your password or adjust the rating level.
