Troubleshooting

These troubleshooting steps can help resolve issues with your LG webOS Signage display. We recommend that you try these steps before reaching out to support, to see if this might resolve your issue for you.

Step	Action	Instructions
1	Clear Cache	Open the ScreenCloud app side menu by pressing the S.Menu button on the remote. Choose Clear Cache from the list. The app will restart automatically and clear the cache.
2	Power Cycle Display	Turn the display off for a few minutes, then power it back on.
3	Update OS	Check for webOS updates and update to the latest version (refer to LG support documentation if needed).
4	Review Known Issues	Review the support library to see if the issue and solution are already documented.
5	Check Power Adapter	Ensure the power adapter is functioning correctly. Replace it or contact the manufacturer if necessary.
6	Check Internet Connection	Test and improve the device’s internet connection if it is weak.
7	Reinstall ScreenCloud App	Delete and reinstall the ScreenCloud app. Use Replace Device when a new pairing code appears to reconnect the same screen license.
8	Remove Unnecessary Apps	Delete unused apps so the device runs only ScreenCloud.
9	Factory Reset	Press Settings → Go to Admin Menu → Toggle Admin Mode ON (default password: 000000 if unchanged) → Select Factory Reset → Confirm. Install the ScreenCloud app again after a factory reset. Use Replace Device to reconnect the same license.
10	If Issue Persists	The device may be faulty. Contact the manufacturer, purchase a media player, or upgrade to a newer LG webOS Signage model.
