Sonos Beam Stopped Working with LG TV (HDMI eARC and Remote Issues)

Hello ​@mpedgjw, welcome to the Sonos Community!

I am sorry to hear you are experiencing issues setting up your Sonos Beam with your LG TV.

You’ve tried quite a few things, most of them I would suggest too. Have you tried to do a network refresh by rebooting all network devices involved too? Start with your Router → Sonos → Controller (Smartphone/tablet)

If you are still getting the “Connection Failed" error message, I would recommend you to Submit Diagnostics within 10 minutes of that happening and then reach out to our Support Team for some live troubleshooting.

They have tools at their disposal to provide you with information and advice, specific to your system and what it reports.

I hope this helps.

Hi ​@Sotiris C. 

Thanks for the reply and the suggestions. I haven’t tried a full network refresh yet, but I’ll give that a go by rebooting the router, the Sonos Beam, and my controller device in the order you mentioned.

I’ve already submitted diagnostics while I was on live chat with Sonos Support, but unfortunately, they weren’t able to resolve the issue and suggested I call the support center. I’ll hold off on that for now and see if the new HDMI cable fixes things when it arrives.

If that doesn’t work, I’m starting to wonder if the speaker itself might be faulty, which is frustrating since I’ve only had it for six months. Hopefully, that’s not the case, but I’ll keep you posted.

Thanks again for your help!

Cheers.

hello
I hope this message finds you well.

I wanted to follow up and ask if you were able to find a solution to the issue we discussed. I’m facing the same problem, and unfortunately, the resets don't seem to be working for me either.

Looking forward to hearing from you and any advice you may have.

Best regards,

Cruz

Unfortunately not ​@aCruz1 

The replacement cable arrived but that didn't resolve it.

I ended up contacting the retailer that I bought it from as it's still under its guarantee and they are going to replace it.

Further information ​@Sotiris C. ​@aCruz1 

I've received the new speaker and it's still not working, so I'm led to believe it's a problem with the TV.

I've contacted LG and am waiting to hear from their technical team, so will let you know when I get a response.

THANKS!!!

The unplug tv trick worked for me!! Samsung 2024.

Stopped working two days ago for no reason at all… Been trying everything, nothing helped, then I read your post.

Great, thanks for posting!

This worked for the LG TV. Still have a bad feeling it will revert to its old ways, but for now - it works, thanks. 

Well, after the TV was turned off at night, then back on - it didn’t work anymore. 

Turned off how? With the power button on the remote, or chassis? Or unplugging from the wall? The former puts the TV in ‘sleep mode’, the latter actually forces the TV to reload its OS when it comes back ‘on’. 

If I were to guess, it does sound like an issue with your TV’s CEC component, but that’s without any hard data to look at. I’d certainly be talking to LG’s customer service. 

Power button on the remote. 

Yep, that doesn’t reset the TV in any way. It merely puts it to sleep, waiting for the next command from the remote. The Sonos would, after a short period of inactivity, switch into low power mode, waiting to get new data coming across the connection.
