JBL Cinema Soundbars feature a Bluetooth-connected subwoofer, the ability to stream sound from your smart device through your soundbar system, the ability to connect other JBL speakers, virtual surround sound support, and much more. Common problems with the JBL line of soundbars includes power problems, audio issues, and subwoofer pairing challenges. Try working through your issues using troubleshooting before exchanging your device, or paying someone else to do it.

The JBL Cinema Soundbar features wireless connection with the subwoofer, Soundshift functionality, which lets you quickly play your smart device audio through the speakers, Bluetooth support, and much more.

No Power

  • First, check the power cable running to the JBL Cinema Soundbar and ensure its not frayed, cut, or damaged in any other way. If the cable is damaged, one option is to try getting a replacement power cable to see if that resolves you problems. It is especially important to check for damage if you have pets, as they can be rough on power cables.
  • Second, try connecting the soundbar to a different power outlet to see if you still experience the same problems. Ideally, connect the device to an outlet that you know works. If the soundbar isn't working at an outlet you know powers other devices, try replacing the power cable first, and then contact the store you purchased the device from to see if you can exchange it.

No Sound

  • Make sure the speaker is actually turned on. The backlight associated with the Power button on the front of the soundbar will be white when the device is turned on, and amber when the device is in Standby mode.
  • Ensure the JBL soundbar isn't muted. The backlight for the Power button will blink white whenever the device is muted. You have to press the "Mute" button on the remote control to un-mute the soundbar; there is no option to un-mute located on the soundbar itself.
  • Validate that you have the right input selected on the soundbar. For example, if you are expecting to hear audio from your Xbox One system, the input you're currently set to play audio from on the JBL Cinema Soundbar should correspond with the connected Xbox One. Also, try cycling through the inputs to see if you connected your device to a different input.
  • Make sure the audio is also turned up on the source device. If the audio is muted or turned completely down on the source device, this can also result in you not hearing any sound through your soundbar.
  • If the device you're not hearing audio from is connected to the soundbar via an optical connection, try connecting the two devices using a different cable type -- such as HDMI. The optical audio hardware doesn't play back the entire array of surround sound formats, and switching the cable may solve your problem.

No Subwoofer Audio

  • The first step is to ensure the subwoofer is powered on. The Power button for the subwoofer is on the back of the device.
  • The soundbar and the subwoofer should be paired out of the box, but occasionally they are not. You can re-pair the soundbar and the subwoofer by first pressing the Wireless Pairing button on the front of the soundbar, and then quickly pushing the "Wireless Pairing" button on the back of the subwoofer. The devices should pair together inside of a 30-second window.
  • If you're still experiencing problems, make sure the two devices are within an acceptable range of each other. The soundbar and the subwoofer should be no more than 30 feet from each other, and there should be a clear line of sight between the two devices, with no devices in between them.

Factory Reset JBL Soundbar

Performing a factory reset of your JBL Cinema Soundbar is a simple way to resolve some hard-to-resolve issues. Additionally, you should always perform a factory reset before getting rid of any piece of technology to ensure that any saved or personal information on the device is erased, which prevents the next owner from accessing it. You can restore your soundbar to its factory settings by holding down both the "Volume +" and "Virtual Surround" buttons for roughly five seconds.

      I bought the JBL 2.1 system and could not pair the sub-woofer. Was replaced by supplier and new system checked at the shop, worked perfectly. Had the same problem at home. tried all the resets and other advice, still does not pair with sub-woofer.

      I lost my JBL 350 remote control, how do I get other functionalities like turning on HAMMAN feature and others not present on the sound bar?

      If it's still under warranty I would try and exchange it.

      I bought you a 5.1 system sound system, and I was very pleased to find technical problems

      so the tape is not connected to the subwoofer, and when it comes to manual no sound from it, there is no bass and it is connected to it

      I hope your answer

      I couldn't get my sub to pair with the soundbar fresh out of the box. The soundbar pairing button would not go into the fast blink or "pairing" mode". Once I tried your factory reset trick it paired perfectly! Thank you Max Dalton!

      The sb recognises my Tv remote and I can pair the sub woofer and sb but there is just no sound. Everything is connected correctly, I've tried turning off and on. The sb works via blue tooth from my partners phone (my phone can't pick it up) but just not work with my Samsung tv. Please help. Thinking I'll be going back to the shop and asking for my money back.
