Our LG sound bar we’ve had for years not used very often. Just started turning on by its self the last time we used it. We turn it off it comes back on. I have to keep it unplugged until we use it.... if it’s not under warranty please advise how this issue can be resolved and we don’t have a Sony tv. We haven’t hooked up anything new either. It’s been the same set up for years.

Hello wishesfre,

Thanks for sharing that you’re also having an issue with your LG soundbar. It’s discouraging to hear that yours is turning on randomly as well. I’d be happy to offer a few troubleshooting tips.

Can you please ensure that firmware is up to date for your sound bar? You can check for an update on LG’s website. Also, please ensure that none of the connections have gotten lose over the years. If you’re outside the manufacturer’s warranty, and the firmware update doesn’t resolve the issue options may not be available to assist you further.

Respectfully,

Has anyone gotten the answer on how to fix my sound bar is only 5 days old and geek squad installed and after the second day it turns itself on and off...

Greetings Gator24,

Thank you so much for joining our community to share your experience. I’m sorry to hear that your soundbar is acting up too, and you’re only 5 days in. As the thread shares at this time we’ve not been able to find a troubleshooting solution that works. I’d highly recommend reaching out the manufacturer to see if they have any advice, and exchanging your soundbar within your Return & Exchange Promise if they don’t.   

Respectfully,

Thank you. I was hoping that maybe Best Buy would have worked towards a solution with the manufacturer

Ok. Well I think I just fixed the issue.

I too bought a SONY 4K TV sometime last year and connected it via optical which caused me headaches in trying to figure out how to keep it from turning on by itself. 

The Problem:

I think Sony TVs send out an optical signal even when the TV is off. I am not sure why it does this but I think it does. Thus, the LG soundbar receives the signal and the AUTO POWER function kicks in and it turns on. Then after inactivity, it turns back off.

The Solution: (Potentionally)

So what I did right now, was:

I turned on my LG bar. Got the Remote to the LG, and toggled off the the AUTO POWER feature by pressing the AUTO POWER button. Then turned it the LG bar off. 

So far it has been almost an hour without it turning on. I am still checking it like every 45 seconds. 

Issues you all may have with this solution:

Some of you may have issues because you may like the feature of turning on your TV and the LG Bar automatically turning on too without having to turn it on separately. 

For me this is not an issue, simply because I hated to see it turn on and also because I use the Logitech 650 Universal Remote, which sends two separate signals to both the TV and the LG Bar. 

So if this is an issue for you guys, the solution would be to figure out how to stop the TV from sending Optical signals when it is turned off

Hope this helps you all.

This is not a solution.  It is just disabling the very feature that was intended to be used for the TV and SoundBar.

I have the same issue with my Sony X930E and LG SJ8. We may need to report this to Sony so that they can fix in their next firmware.

[tonysix00]

No, you are disabling a feature that LG intended for LG soundbars to use with LG TVs. My comment is a solution for getting the LG soundbar to work with an Sony TV.

So by turning auto on, we have to manually switch on the LG SoundBar every time?
