For OLED, LED, LCD, and PDP products, it may take some time to show an image when you turn on the power.
How to fix
See if LG logo shows up on the screen when you turn on the power.
If you are using set-top box, check if the set-top box power is on.
※ For OLED and some models, LG logo doesn’t appear on the screen when turned on.
You need an inspection by an engineer if you have any symptom as below.
1. Standby lamp blinks for more than 30sec. or power is turned off again after blinking or ‘click-clack’ sound
from the back of the product repeats.
2. Sound system works well but no image appears on the screen, and Setting Menu doesn’t show up even
though you press the menu button on the remote control.
