LG webOS / LG NetCast
LG TV remote app for iPhone: webOS pairing
For a compatible LG webOS TV, connect the iPhone and TV to the same home network, allow Local Network access and approve the TVRemoteX connection on the television. Keep the TV awake during setup. Network wake and text entry depend on the model and TV settings. Exact support still depends on the TV model and software version; check the manual for your model if a step does not match.

Before pairing your LG TV
Does this guide cover webOS and older NetCast TVs?
The connection method depends on the LG television's system. Check the TV's About or support information first. Compatible webOS models can show an approval request, while older NetCast models can use a different pairing flow. Follow the prompt actually shown by your television.
What should I test immediately after pairing?
Return to the TV Home screen, then try Home, a direction button and volume individually. Test text input in an ordinary search field next. Record which action fails rather than treating all features as one compatibility result.
Does enabling TV On With Mobile guarantee wake?
No. LG documents this setting for supported models, but network standby, firmware and the connection method also affect wake. Test a simple command with the TV on first; check wake separately after the TV enters standby.
Can I use TVRemoteX if LG ThinQ works?
ThinQ can help establish that the television is reachable through LG's own setup. TVRemoteX still needs its own supported connection and any required TV approval. Keyboard, app launching and wake must be checked separately.

Connection steps
Keep the TV awake, then select it in TVRemoteX
Leave the TV on its Home screen, open TVRemoteX, start discovery and choose the matching device name. Do not approve a request you did not initiate.
Authorize the LG TV connection
Complete the approval prompt shown by the TV. If no prompt appears, review its connected-device permissions and retry. Older NetCast models can use a different flow; TV On With Mobile is a separate wake setting.
What to check for this route
LG's TV On With Mobile setting is a wake setting described for LG ThinQ on selected models. It is not evidence that TVRemoteX can wake every webOS TV.
Verify control before relying on advanced features
Test Home, Back and one volume command first. Keyboard, app launch, wake and casting are separate capabilities and may not be exposed by the selected route.

Approve the request on the TV. The TV may remember the authorization for later connections.
TV On With Mobile is separate from first-time authorizationDepending on the model and software, the TV may show an approval prompt or PIN.
Menu location changes by webOS generationOlder vendor protocol with narrower capabilities and model-specific setup.
Older models can use a PIN and expose fewer commandsSymptoms and fixes
| What you see | Likely cause | What to do |
|---|---|---|
| The TV does not appear | Local Network permission, guest Wi-Fi, VPN or client isolation is blocking discovery. | Enable iOS Local Network access, use the same non-guest LAN, pause the VPN and rescan with the TV awake. |
| No approval prompt appears | The request was previously denied, an old authorization is stored, or the TV is on a different platform route. | Remove the old authorized device on the TV when that menu exists, restart the TV, confirm its platform and initiate one new connection. |
| The pairing code is rejected | The code expired, belongs to an earlier session or was entered incorrectly. | Close the old dialog, start pairing again and follow the current prompts exactly. |
| Power off works but wake does not | Deep standby disabled network wake, the TV lost Wi-Fi, or this connection method does not support wake. | If your model offers a network or mobile-device wake setting, enable it. Otherwise turn on the TV with its physical remote and reconnect. |
| Keyboard input is unavailable | The active route does not expose text input or the TV is not focused in an editable field. | Open a search or sign-in text field on the TV, then retry. Use the on-TV keyboard when the route remains unavailable. |
| An app shortcut is missing or will not open | The TV did not report that app, the app is not installed, or its identifier differs by model or region. | Install and open the app once on the TV, refresh the app list, and do not assume a shortcut exists on every region. |
| A photo works but a video does not | The receiver cannot fetch or decode that media format, or protected streaming content blocks redistribution. | Try a common local file on the same LAN. Use the streaming app's own AirPlay/Cast control for protected services. |
