Troubleshooting JBL Cinema Soundbar Problems

Introduction

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.

Questions & Answers

Question: Why won't my JBL Soundbar and subwoofer pair?

Answer: They should have been paired automatically. You should have a "Wireless Pairing" button on each device. Try pressing both buttons at the same time. I would also make sure they are as close to each other as they can be.

Question: Audio comes through on my Xbox One and PS4 just fine. However, on my PC if any audio begins (like in a video or video game) the sound takes a little over a second to begin coming through. Do you know what could be the issue? There is no synching issue, it just is silent for a second before it begins. I am using high quality HDMI cables, all of the same type and brand, and running each device into the sound bar.

Answer: Try right-clicking the audio icon in your notification tray, and then clicking "Playback Devices." Your sound bar should appear in that list somewhere. Right-click it, and then click "Configure Speakers." See if adjusting those options helps. Also, if you have any Bluetooth devices connected to your computer try disconnecting all of those to see if that helps.

My JBL 2.1 soundbard sound loudness has been reduced after 12days what is the issue please give a answer

Laurenz Schmidt on January 04, 2020:

Identical problem as reported by Stephen Ghan. Intermittent failure to power up or abruptly losing power. Re-seating the power plug several times brings the unit back up, but after a few hours or days for no apparent reason it shuts off again. Checked outlet and cable, seems like a defect in the internal power supply. Harman tech support suggested to reset to factory settings. Did not make a difference. now waiting on what they will tell me next.

Stephen ghan on December 24, 2019:

My JBL Cinema SB450 sound bar & subwoofer sounds great but the volume/sound fades in and out constantly....comes & goes every 5-10 minutes or so. Using the Optical cable from TV to sound bar, do you have any suggestions?

My sb150 has no surround button, how do I fatcory reset?

Shawn on February 02, 2019:

JBL 3.1 4K Ultra amazing unit it stopped working at 6 months. Sound bar won’t turn on with remote or power button no indication that sound bar is on, no lights, no sound, no connected signal on our devices. Reached out to JBL and more than 10 emails, time zones, different JBL regional reps, and passed off and today passed back to original rep. So frustrating! I want it to work or be replaced butnlocal retailer does not carry it any more and will not give return because I need to only deal with manufacturer on 1yearwarranty. Now Bose is the next quality product at massive price ranges.

Tom on January 12, 2019:

I bought a JBL 3.1 soundbar. Everything works fine but having issues with my cable box remote operating the sound bar every time I use it. Can’t figure out the problem and how to fix it. Any ideas

Frederick Boitumelo on October 06, 2018:

These cockroaches should in future include a wired option of this subwoofer this pairing of theirs is frustrating mine is to be an end user not a technician

romeo rosales on September 21, 2018:

i have JBL SB 350 but my subwoofer is not working NO POWER!where i buy power supply of this unit or the subwoofer power supply?

Steven Cohoe on August 31, 2018:

I had thr same problem, but after 2 days of trying different methods, contacting JBL for help and information, nothing came up to aid me. I did find out one afternoon by talking to a technician in the store that sold me the product, that by pressing the reconnect button on the subwoofer 15 times would reset the subwoofer. This worked for me and this little piece of info wasnt anywhere to be found. I hope this helps anyone with thr same problem.

Rob on June 20, 2018:

I have this system and I love it. I have had an issue where I’ll turn the tv on and then it will be 5-10 minutes before the sound bar sound actually works with the tv. It is connected by the HDMI ARC and I did not have this issue originally when I set up my system. Any thought as to how to fix this?

Brett on April 14, 2018:

My SB400 quite producing sound. I tried factory reset listed below (surround and volume - buttons for 10 seconds simotaniously) and it did not seem to reset. Would there be other reset commands you could share?

Behng on March 28, 2018:

How to reset:

Switch sb350 ON

Press and hold the Surround and Volume (-) buttons simultaneously for about 3-4 seconds,then let go. The Source selection button flashes amber, followed by the power button and source buttons flashing several times

The soundbar is now reset

Becca Smith on March 24, 2018:

How do you pair multiple Bluetooth devices? My subwoofer is connecting but no Lenovo Yoga or iPhone.

Gerald on March 24, 2018:

Having the same issue with my SB350, sometimes no sound from the soundbar and sometimes sound is broken. You can hear it in the dialogue from movies

Joaquin on March 05, 2018:

Max Dalton (author) from Greater St. Louis, Missouri on February 06, 2018:

You bet. Glad it helped!

Max Dalton (author) from Greater St. Louis, Missouri on February 05, 2018:

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

Nana on January 13, 2018:

IVAN on December 31, 2017:

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

Chris Brett on October 18, 2017:

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!

Kerry on August 17, 2017:

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.
