Respuesta a "LG 47LB5900-UV TV display is flashing / flickering on and off"Lol i had the same or similar symptoms. After a few weeks of freakimg out i was smart tv page with the live preview screen in the top left. And the preview screen blinked showed lines not the whole screen. That immediately made me realize the tv is perfectly fine. Its either my cable or computers graphics card. So my tip for all you fellas is check to see if the flickering still happens when your in a tv menu or smart home page.
