  If you're experiencing no sound with your LG Home Theater System, first ensure the equipment connected with the audio cable is set to receive the disc signal output by selecting the correct input mode on the audio receiver. Also, verify that the connected equipment is powered on. If the [AUDIO] options are set incorrectly, adjust them to the correct position. Finally, if the player is in reverse play, fast forward, slow motion, or pause mode, return to normal playback.

  If your LG Home Theater System player does not start playback, make sure the disc is inserted correctly with the playback side down. Ensure that you are using a playable disc, verifying the disc type and regional code. If a rating level is set, try changing it. If the disc was recorded on another unit, finalize the disc on that unit.

  If your LG Home Theater System's connected HDMI device does not output sounds, note that some HDMI-compatible devices do not output sounds. If your TV is not capable of handling 96 kHz sampling frequency, set the [Sampling Freq.] option to [48 kHz] on the setup menu. If your TV is not equipped with Dolby Digital and MPEG decoder, set the [Dolby Digital] and [MPEG] options to [PCM] on the setup menu. If your TV is not equipped with DTS decoder, set the [DTS] options to [OFF] on the setup menu.
