LG TV Bluetooth not pairing or connecting — headphones, earbuds, soundbar & speaker issues

Technician avatar Technician
Hey! We’ll track down why your LG TV Bluetooth is not pairing and get it talking to your headphones or soundbar again. A few questions so we don’t guess:
• Exact LG TV model or year (e.g. LG OLED C2, NanoCell, UHD, webOS 5/6/22)?
• What are you trying to connect — Bluetooth headphones, earbuds, soundbar, speaker or game controller? Brand/model helps a lot.
• In webOS Bluetooth settings, do you see the device in the list, or does the TV just say “No devices found” or “Failed to connect”?
• Did this start after a webOS software update, firmware update or a factory reset of the TV or Bluetooth device?
The more detail we have, the faster we can fix an LG TV that won’t pair Bluetooth or keeps dropping the connection instead of randomly rebooting everything.
Customer
It started after a software update on my LG OLED a few days ago. Since then LG TV Bluetooth won’t pair with my Sony headphones or my JBL soundbar. Both used to work fine. Now the TV either says “no devices found” or it shows the device but then says “unable to connect”. Bluetooth works fine with my phone, so it’s definitely the TV.

Got it — that’s a classic LG TV Bluetooth not connecting after update situation.
After a webOS or firmware update, a few things can happen:
• The TV resets Sound Out back to “TV Speaker” or HDMI ARC/eARC → Bluetooth devices stay paired but never get audio.
• The list of registered Bluetooth devices gets corrupted so pairing fails or spins forever.
• Other outputs (ARC soundbar, AV receiver) get priority over Bluetooth headphones, so the TV keeps switching back.

We’ll:
1) Confirm the TV still supports Bluetooth audio and the feature is enabled.
2) Clean up the registered Bluetooth list and re-pair from scratch.
3) Make sure webOS is set to use the Bluetooth device as Sound Out, not just TV speakers.
If needed, we’ll also tweak power and Quick Start+ so your LG TV Bluetooth connection stops dropping randomly.
Customer
When I go to Sound > Sound Out, I see “Use Wireless Speaker (Bluetooth)”. If I open it, sometimes the headphones show up, sometimes not. When they do, I click connect, it shows “connecting” for a few seconds, then nothing happens and it goes back to TV speakers. So basically LG TV finds the Bluetooth device but won’t pair.

Perfect, thanks — that helps. Let’s do a clean pairing, which fixes most cases where LG TV Bluetooth is not pairing properly.
Step 1 — Make sure the Bluetooth device is really in pairing mode
• Turn off Bluetooth on your phone/tablet so the headphones or soundbar aren’t auto-connecting there.
• Put the device into pairing mode (LED flashing blue/white, or a “pairing” voice prompt). If it’s been paired to many things, factory-reset the headphones first.

Step 2 — Restart the LG TV’s Bluetooth stack
1) Long-press the Power button on the remote until the LG logo appears (this fully reboots webOS).
2) After restart, go to All Settings > Sound > Sound Out > Use Wireless Speaker > Bluetooth Devices.
3) If you see your headphones in Registered devices, highlight them and choose Delete / Forget device.
4) Now choose Search / Device Search so the TV scans for new Bluetooth devices.

Once we find the device as “connectable”, we’ll set it as the main output so your LG TV Bluetooth audio actually routes there.
Customer
I rebooted the TV and deleted the old entries. The headphones now show up under “Connectable devices” and it says “Connected” for a moment, but the sound is still coming from the TV speakers. If I open Sound Out again, it sometimes jumps back to HDMI ARC. I mainly use a soundbar on ARC but wanted Bluetooth headphones for late-night watching.
Technician avatar Technician
That’s webOS giving priority to ARC. We’ll explicitly tell the TV to use Bluetooth Sound Out instead.
Step 3 — Set LG TV Sound Out to Bluetooth only
1) Go to All Settings > Sound > Sound Out.
2) Instead of “TV Speaker” or “HDMI ARC/eARC”, pick:
  • Use Wireless Speaker > Bluetooth Device, or
  • LG Sound Sync (Wireless) on some older models.
3) Choose your headphones/soundbar from the list and wait until it shows as the active device.

On some models there’s also “Internal TV Speaker + Bluetooth”. If you only want headphones, pick the pure Bluetooth option so the TV doesn’t keep flipping back to ARC.
Once Sound Out shows the Bluetooth device in bold, test again with Netflix, YouTube, etc. This usually solves “LG TV Bluetooth connected but no sound”.
Customer
Setting Sound Out directly to Bluetooth Device helps. The headphones now play audio, but sometimes after I turn the TV off and back on, LG TV Bluetooth disconnects and I have to redo the pairing or re-select them. Is there any way to make it more stable?
Technician avatar Technician
When LG TV Bluetooth keeps disconnecting after standby, it’s usually a power/standby feature or interference.
Step 4 — Improve Bluetooth stability
• In Settings > General > Additional Settings, turn Quick Start+ off, then power the TV off for 30 seconds and back on.
• Keep the Bluetooth headphones or soundbar within ~3–5 meters of the TV, with no big metal objects or routers directly between them.
• If the device can pair with multiple things, make sure it’s not auto-connecting to your phone at the same time — that’s a common reason for LG TVs to drop Bluetooth audio.
• Remove old devices you no longer use from Registered devices so the TV doesn’t get confused between multiple speakers/headsets.

After this, most people find their LG TV Bluetooth connection stays paired across power cycles instead of restarting every time.
Customer
That helps with the headphones. I also have a Bluetooth speaker that the LG TV doesn’t see at all. It works with my phone, but in the LG TV Bluetooth device list it never shows up, even on a fresh search. Is that just incompatibility?
Technician avatar Technician
Good question. Not every Bluetooth speaker works the same way with LG TVs.
• Some older LG models only support LG Sound Sync (wireless) — mainly LG-branded Bluetooth soundbars/headsets.
• Certain speakers use Bluetooth profiles meant for phones (like hands-free) that TVs don’t support.
• On a few LG TVs, Bluetooth is limited unless you add a specific LG dongle.

To check:
1) Look in your TV’s manual/specs for Bluetooth audio / LG Sound Sync support and any compatibility notes.
2) Put the speaker in pairing mode (not just “connected” to your phone) before starting Device Search on the TV.
3) If the TV still never detects it while other Bluetooth headphones work, it’s likely a compatibility limitation, not a fault.
In that case, using a small Bluetooth transmitter on the TV’s optical or headphone output is often the easiest workaround.
Customer
Makes sense. Is there anything I can do now so the next webOS update doesn’t break Bluetooth again? I don’t want to keep troubleshooting every time there’s an LG TV firmware update.
Technician avatar Technician
Totally fair. Let’s “future-proof” things so the next update doesn’t leave LG TV Bluetooth not pairing all over again.
Best practices for LG TV Bluetooth
• Keep the TV on the latest stable firmware, but avoid interrupting updates in the middle.
• Stick to a small set of trusted devices (main soundbar, main headphones) instead of constantly pairing dozens of Bluetooth gadgets.
• Every so often, clear the registered device list and re-add your main headset/speaker to avoid pairing glitches building up.
• If you rely on HDMI ARC/eARC most of the time, get used to quickly switching Sound Out between ARC and Bluetooth Device instead of having both fight for priority.
• If a specific firmware version is known to cause LG TV Bluetooth issues, it can be worth delaying the update for a bit until LG releases a fix.
These small habits make Bluetooth on LG TVs much less fragile long-term.
Customer
What about older LG TVs that don’t seem to have Bluetooth at all? A friend has an LG model where the menu doesn’t show any Bluetooth option. Can that be fixed with an update or app, or does he need some kind of adapter?
Technician avatar Technician
Great that you asked — this is a separate but common issue.
• If Sound Out has no “Bluetooth” or “Use Wireless Speaker” option, that LG TV likely doesn’t have built-in Bluetooth audio.
• Unfortunately, you can’t add full TV Bluetooth support just with a software update or app.

The usual fix is a Bluetooth audio transmitter:
• Plug a transmitter into the TV’s optical (Digital Out), RCA, or headphone jack.
• Put both the transmitter and headphones/speaker into pairing mode until they connect.
• Leave the TV’s Sound Out set to whichever output you used for the transmitter (e.g. Optical PCM).
It’s not as slick as built-in webOS Bluetooth, but it’s the best way to get wireless audio on models with no Bluetooth option.
Customer
After deleting the devices, rebooting, turning off Quick Start+, and forcing Sound Out to Bluetooth Device, everything works. The LG TV Bluetooth pairs and reconnects with my headphones now without errors. Thanks a lot!
Technician avatar Technician
Summary: when an LG TV Bluetooth device won’t pair or connect after an update, first reboot the TV fully, put the headphones/soundbar into pairing mode, then delete and re-add it under Sound Out > Use Wireless Speaker > Bluetooth Devices. Set Sound Out to the Bluetooth device, not ARC or TV Speaker, and turn off Quick Start+ if connections keep dropping. If the TV never sees the device or has no Bluetooth option at all, a small Bluetooth transmitter on the TV’s audio output is the fastest workaround. Not sure which menu path your webOS version uses? Open the chat and an expert will walk you through it step by step.

Quick answer: the accepted fix

Accepted fix when LG TV Bluetooth is not pairing: fully reboot the TV, put your headphones, earbuds or soundbar into pairing mode and delete any old entries under Sound Out > Use Wireless Speaker > Bluetooth Devices. Run a new device search, select your Bluetooth device and set Sound Out to that device (not TV Speaker or HDMI ARC). If pairing still fails, turn off Quick Start+, remove other nearby Bluetooth connections and try again.

Why LG TV Bluetooth stops pairing after an update

Most LG TV Bluetooth pairing problems after an update come down to a few things: the TV’s sound output switching back to TV speakers or ARC, a corrupted list of registered Bluetooth devices, or minor firmware glitches in webOS. When this happens, you might see “no devices found”, the headphones briefly showing as “connected” with no sound, or a soundbar that keeps stealing audio back from Bluetooth headphones. Cleaning up the Bluetooth list, re-pairing from scratch and forcing Sound Out to the Bluetooth device usually restores a stable connection.

How to test if your LG TV Bluetooth connection is really fixed

After pairing, leave your Bluetooth headphones or soundbar connected while you watch a show for at least 10–15 minutes. Try playing video in Netflix, YouTube and a live TV channel, and walk a few meters away from the TV. If the audio stays in sync, doesn’t cut out, and the TV reconnects automatically next time you power it on, your LG TV Bluetooth pairing is in good shape. If sound drops when ARC is plugged in or when you turn your phone’s Bluetooth on, you likely still have a priority or interference issue to solve.

LG TV Bluetooth not pairing — quick troubleshooting tips

Most cases are fixed by cleaning the Bluetooth list, re-pairing, and setting Sound Out correctly.

Quick path: power-cycle the TV with a long press of the remote Power button, then delete old devices under Bluetooth Devices and pair again while your headphones or soundbar are in pairing mode. Set Sound Out to “Use Wireless Speaker > Bluetooth Device” so the LG TV doesn’t keep jumping back to HDMI ARC or TV speakers. Turn off Quick Start+ if Bluetooth disconnects after standby, and keep other phones or tablets from auto-connecting to the same headset at the same time.

FAQ

Why did my LG TV Bluetooth stop pairing right after an update?

Updates can change Sound Out back to TV speakers or ARC, clear or corrupt the list of registered devices, or temporarily glitch webOS Bluetooth. After that, your LG TV may show “unable to connect” or “no devices found” until you reboot the TV, delete old pairings and re-pair your headphones or soundbar from scratch.

Can every LG TV connect to Bluetooth headphones or speakers?

No. Many newer LG smart TVs support Bluetooth audio / LG Sound Sync (wireless), but some budget or older models don’t include Bluetooth audio at all. If Sound Out has no Bluetooth or Wireless Speaker option, you’ll need a separate Bluetooth transmitter on the TV’s optical, RCA or headphone output to use wireless headphones or speakers.

How do I reset Bluetooth devices on my LG TV?

Go to All Settings > Sound > Sound Out > Use Wireless Speaker > Bluetooth Devices. Remove or delete all devices you no longer use, then run a new device search and pair again with the headphones or soundbar in pairing mode. This often fixes LG TV Bluetooth not pairing or connecting errors.

When should I use a Bluetooth transmitter instead of the TV’s Bluetooth?

Use a Bluetooth transmitter when your LG TV has no Bluetooth at all, when it only supports LG-branded devices, or when you still get audio dropouts or lip-sync issues with built-in Bluetooth. A quality transmitter on the TV’s optical output can give more stable audio, especially for gaming or long-range headphones.
