Audio Problem No sound. No sound is coming from the subwoofer. The volume decreases when the sound bar is turned on. No surround effect. Noise is heard. Cause Another input source is selected. The mute function is activated. The volume is too low. The power cable of the sound bar is not connected properly. Input jacks on both devices are connected. Signals that the sound bar cannot play back are being input. The volume of the subwoofer is too low. The playback source does not contain low-frequency signals. The automatic volume adjustment function worked. To prevent excessive loudness, the sound bar automatically controls its volume within a certain level when the sound bar is turned on. Stereo playback is selected. The volume is too low. The TV or playback device is set to output 2 channel audio (such as PCM) only. The audio is output from the TV built-in speakers. The listening position is too close to the sound bar. The installation position selector switch is not set appropriately. The sound bar is too close to another digital or high-frequency device. Remedy Select an appropriate input source (p.8). Cancel the mute function (p.9). Turn up the volume (p.8). Make sure that the power cable of the sound bar is connected to an AC wall outlet securely (p.6). Connect the input jack on the sound bar and the output jack on the external playback device. Change the digital audio output setting on the playback device to PCM or Dolby Digital. Turn up the volume of the subwoofer (p.8). Play back a sound source containing low-frequency signals, and confirm that the sound is output from the subwoofer. If necessary, turn up the volume (p.8). Select surround playback (p.9). Turn up the volume (p.8). Change the digital audio output setting on the TV or playback device to Dolby Digital or BitStream. Set the TV volume to minimum (p.6). Listen from a position at some distance from the sound bar. When placing the sound bar in front of a TV, set the installation position selector switch to "T." When attaching the sound bar to a wall, set the installation position selector switch to "W." Move those devices away from the sound bar. Remote control Problem The sound bar cannot be controlled using the remote control. The TV cannot be controlled using the TV's remote control. The sound bar does not learn TV's remote control operations. Sound is coming from the TV when the sound bar volume is turned up with the TV's remote control. (when TV's remote control learning function is used) Cause The sound bar is out of the operating range. The batteries are weak. The remote control sensor of the sound bar is exposed to direct sunlight or strong lighting. The remote control sensor of the TV is hidden by the sound bar. The TV's remote control key was not held down long enough. The TV's remote control does not use infrared signals. (Some remote controls may not work even if it uses infrared signals.) The position where you operated the TV's remote control is not appropriate. The batteries of the TV's remote control are weak. The remote control sensor of the sound bar is exposed to direct sunlight or strong lighting. The transmission of the remote control signal was disturbed by the TV screen light. The cable or satellite set top box's remote control is used for learning. Audio output is enabled on the TV. Remedy Use the remote control within the operating range (p.2). Replace with new batteries (p.2). Adjust the lighting angle, or reposition the sound bar. Adjust the installation position of the sound bar so that the remote control sensor of the TV is not hidden by the sound bar when operating the TV from the ordinary operation position. Hold down the key for more than 1 second twice or three times (p.12). The TV's remote control learning function cannot be used in this case. Use the sound bar's remote control to operate the sound bar. Operate the TV's remote control at the appropriate position (p.12). Replace with new batteries. Adjust the lighting angle, or reposition the sound bar. Turn off the TV and perform the learning operation again (p.12). Use the original TV's remote control for learning, then use the set top box's remote control to operate. Change the TV setting to disable the TV speaker output. If a setting to disable the speaker output is not available on your TV, try the following methods. - Connect headphones to the headphone jack on the TV. - Set the TV volume to minimum. En 17
