Probably not a back light problem. What happens if you activate the screen test display?

    Sorry, I cannot tell you how access such a test display, even if it is available, because every TV, and every remote is different. If you don't have access to a manual, try looking using Google.

MY SHARP AQUOS 70" TV HAS STARTED TO HAVE A DARK SHADOW ACROSS 1/2 OF THE SCREEN WHILE THE OTHER 1/2 IS PERFECT. DO I HAVE A HDMI INPUT ISSUE OR IS THE TV BROKEN?


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
