LG C1 OLED Oled Clicking Sound After Turning Off
System Nominal
The clicking sound is the physical actuation of a mechanical relay on the Power Supply Unit. LG OLED TVs are programmed to run a 'Pixel Refresher' cycle after being turned off to maintain panel uniformity; the relay clicks once when the screen turns off and a second time several minutes later when the maintenance cycle completes and the TV enters full standby.
