Before performing a factory reset, it's essential to perform these preliminary checks. These simple steps can often resolve the issue without erasing the device.
1. Confirm your firmware version
Outdated firmware is the most common cause of black screens and performance problems. LG and Signagelive work together to release updates that improve stability and compatibility.
How to check: Using your LG remote, press the Settings button. Navigate to General > System Information (this path may vary slightly, sometimes appearing under Admin Settings or simply Information).
Note the Software Version listed on the screen.
Action: Contact the Signagelive support team using this version number. They can confirm if it's the latest version and provide the necessary files and instructions if an update is required.
2. Verify content encoding
Signagelive can play a huge variety of content, but the LG webOS player has specific requirements for smooth playback. Poorly encoded media, especially videos, can cause the player to freeze or show a black screen.
Resolution: Ensure your content's resolution does not exceed the native resolution of your screen. For example, use
1920x1080pixels for a Full HD display and3840x2160for a 4K/UHD display.Format & Codec: The recommended video format is MP4 using the H.264 video codec. This is the most widely supported and efficient format for LG system-on-chip displays.
Action: Re-encode any problematic assets to match these specifications and republish them to your player. If the black screen disappears after publishing a simple image playlist, it strongly indicates a video encoding issue.
If you are in a hurry, you should revert your screen back to a factory state, and then let our team know the assets you are trying to deploy. We will identify the above details for you and let you know about next steps. See below for guidance on how to revert your player to its factory settings:
Performing a Factory Reset
If the initial checks don't solve the problem, a factory reset is the next logical step. This will erase all local settings, content, and applications from the display, returning it to its original out-of-the-box state.
Please Note
A factory reset is irreversible and will remove the Signagelive player. You will need to reconfigure the display and reactivate the player after ward.
The Process
Press the Settings button on the remote control.
Navigate to the General menu.
Select Factory Reset. You may need to enter an administrator PIN. The default PIN is usually 0000.
Confirm that you want to proceed with the reset. The display will erase its data and restart automatically. This process may take several minutes.
Reinstalling and Activating Signagelive
After the factory reset is complete, the display will launch into its initial setup wizard. Follow these steps to reinstall the Signagelive player.
1. Initial LG Setup
Follow the on-screen prompts to configure basic settings like language, country, and time zone. When you reach the end of the setup, you'll be at the home screen.
2. Configure the Signagelive Player URL
You need to tell the display where to find and launch the Signagelive application.
Press the Settings button on the remote and navigate to SI Server Settings.
Select Application Launch Mode and set it to Local.
In the Application Type dropdown, select URL.
Enter the correct Signagelive client URL based on your display's webOS version:
webOS 3.2, 4.0, 4.1:
http://clients.signagelive.com/lg/v3/latest/webOS 6.0:
https://clients.signagelive.com/lg/v4/latest/
Save the settings and reboot the display by turning it off and on again.
3. Activate Your Player
When the display reboots, it will load the Signagelive player, which will show a 6-digit activation code.
Log in to your Signagelive network at
https://login.signagelive.com.Navigate to the Players section of the dashboard.
Click the Add Player (or
+) button.Enter the 6-digit code shown on your LG display.
Give the player a name, assign a license, and click Save.
Your display will now connect to your network, download its content, and begin playback.
