We regret the inconvenience you have experienced with this Sound Bar. It is recommended to test this Sound Bar with another television in order to see if the failure is with the audio system, or if it might be the output signal from the TV itself. If the problem persists, then this unit may require service. Please contact our Customer Interactive Center at 800-243-0000 to make proper service arrangements for this device.

Question

Remote does not work after TV with sound bar have been on for less than 30 mins.

NB 3520A Sound Bar System is hooked up to a fairly new Samsung LED TV. System works well with the remote control. But after less than 20 mins. the remote no longer works for any functions. The touch buttons on front panel work. Remote control only works for a short time when system is first turned on after being off for at least an hour.

Yes, these devices will be compatible with your Sound Bar. Connect your BD370 to your TV using the HDMI cable. Once connected, use the provided Optical cable from the OPTICAL Digital Audio Output, from the TV, to a matching Optical INPUT on the Sound Bar. After this, simply access the AUDIO MENU on the TV, and deactivate the TV SPEAKER setting. This will send TV and BluRay audio out to your Sound Bar.

I have a 55 inch LG LCD flat panel TV and a set top cable box by Verizon Fios. Will the remote for this STB be able to control the sound for this sound bar, or would I still need to have two remotes?

All codes to be used will be located in the setup instructions for the Universal Remote Control. If you have experienced trouble in locating codes for LG, you may also try using Zenith or Goldstar codes, as some of these coincide with LG frequencies.

We regret the inconvenience you have experienced with this Sound Bar. Is this low volume on all channels and videos, or just on TV, or just certain channels? If it is certain channels only, then the unit is operating properly, and the broadcast station has changed a GAIN setting. If it is all TV channels, but not videos, then it might be recommended to change out the audio/video cable, between the TV and Cable box, or the wall, and try it again. However, if this reduction in volume is on all settings, then it would be recommended to check the cables between the TV and the Sound Bar. If this does not resolve the matter, then the unit may require service. Please contact our Customer Interactive Center at 800-243-0000 for additional assistance and/or service if necessary.

We regret your dissatisfaction with the installation instructions provided with this LG Sound Bar. The unit is designed for connection to a television using a single OPTICAL Audio cable. Use the provided Optical cable to connect the OPTICAL Digital Audio Output jack, on the TV, to the Optical IN jack on the Sound Bar. Access the AUDIO menu on the television. Set the TV SPEAKER setting to its OFF setting. Once this has been done, all audio signals should be automatically output from the TV to the Sound Bar. If this does not resolve the matter, please contact our Customer Interactive Center at 800-243-0000.

Question

Just purchased sound bar and the bluetooth works but the unit doesn't work when hooked to the television.

We just purchased the NB3520A yesterday at Best Buy and the bluetooth works perfectly but when we hooked it up to the tv, it does not work. The remote will not operate any functions and the unit makes a really loud squeaking noise and then shuts off. There was not a manual in the box. Are there any suggestions? We did purchase an optical cable and just picked the television up yesterday as well. Is there a website to view an electronic version of the manual? Help!

We regret the difficulty you have experienced with these products. A copy of the owner’s manual is currently available on our website, at http://www.lg.com/us/support-produc.... For proper operation with your TV, connect it using the Optical Cable provided with the Sound Bar and, if this is a LG television, turn off the TV SPEAKER setting in the audio menu of the TV. This should allow the two devices to operate properly.

Question

Can the LG LSB316 Bluetooth Sound Bar work with my PC through bluetooth

MY PC has bluetooth built-in. I would like to stream music from my PC to the LG LSB316. It seems to work sporatically but chokes at times. I also have to reconnect often, but it does work although not smoothly. My PC is 8 feet away from the LSB316 with a straight line of sight with no obstructions. The LSB316 works via bluetooth smoothly with my Ipod & or smartphone, but seems to choke often using my PC via bluetooth to stream music to it. Why is that?

We regret the trouble you have experienced with connecting your computer to this Sound Bar. The sound may be interrupted when the connection interfered by another electronic wave. Pairing is limited to one Bluetooth device per one unit, and multiple pairing is not supported. An electrical malfunction can occur due to devices using same frequency; such as Medical equipment, Microwaves or wireless LAN devices. In these cases, the connection will be disconnected. If you have additional questions regarding these possibilities, or others, please contact our Customer Interactive Center at 800-243-0000.

We appreciate your interest in the operation of this television. The PORTABLE INPUT connection is designed to operate with small speakers that do not require amplification, such as computer speakers. It will likely not support a Sound Bar. We cannot offer any suggestions of compatibility between a remote control from DirecTV and a Sound Bar for which we do not have a brand or model number listed.

Why does my brand new LG TV not have an optical cable for sound bar?
