At a Glance

If your LG monitor has no picture or no power when you turn it on, some simple troubleshooting can get it back up and running

Try This

  1. Confirm the power LED is turned on.

    Even if turned off in settings, the monitor’s power LED should illuminate briefly when the power button is pressed indicating power is being received.

  2. Test the outlet

    Power outlets can sometimes malfunction. Unplug the monitor and test the outlet with a cellphone charger or lamp to ensure it’s still working. If using a surge protector, try plugging the monitor directly into the wall outlet.

  3. Confirm the power cord is fully connected

    The power cord can sometimes become loose if the monitor was moved or cleaned. Ensure it is fully connected to the wall outlet and the rear of the monitor.
