If your LG Home Theater System isn't recognizing the connected USB storage device, try using a different USB cable, as some cables may not provide enough current. Avoid using USB extension cables or USB hubs, as they can prevent recognition. Note that the unit doesn't support USB devices requiring additional program installation on a computer. The unit supports only USB Flash Drives and USB External HDDs with FAT32 or NTFS format.

If your LG Home Theater System remote control isn't working, make sure it's pointed directly at the unit's remote sensor and is not too far away. Also, check for any obstacles between the remote and the unit. Finally, verify that the batteries in the remote control are not exhausted.

Connect the player to your TV with an HDMI cable (Type A, High Speed HDMI™ Cable). Your TV may not support “HDMI 3D mandatory format.” Check that the [3D Mode] option in the [Settings] menu is set to [On].

If your LG Home Theater System isn't working correctly, try turning off the power to both the unit and any connected external devices like your TV, Woofer, DVD-player, or Amplifier, and then turn them back on. If that doesn't work, disconnect the power cord of the unit and all connected external devices, wait a few seconds, and then reconnect them.
