If it’s does it on all inputs you have a defective tv
Sorry, there was a problem. Please try again later.A simple solution to the common issue of LG TV flickering is to unplug the TV from the wall and wait 60 seconds. After unplugging the TV, hold down the power button on the TV itself for 30 seconds, not on the remote. This helps to drain any remaining power in the TV and allows it to reset properly. ^Jai.
