What Display Turned Off / Not Turned On (Brightness Setting) Means
A display that appears turned off, or seems like the unit isn't turning on, is not necessarily a fault - LG's dedicated article explains the screen brightness may simply be set to Display OFF, which is adjusted through the remote control rather than a button on the unit itself.
Common Causes of Display Turned Off / Not Turned On (Brightness Setting)
- Screen brightness setting turned down to Display OFF via the remote control
🔧 One Safe Check You Can Try
Use the remote control to adjust screen brightness back up; check for a dedicated brightness button, which may be a standalone button or configured as a dual-function button depending on your model and remote.
⚠ Why You Shouldn't Go Further Than That
- There's no fault here if the unit is otherwise running normally - confirm the unit is actually cooling/heating as expected (feel for airflow, check the room temperature trend) before assuming a power problem rather than just a brightness setting.
