The HX823 is edge lit by LEDs. Code 4 is indeed a backlight problem. A test of backlights is to remove the LVDS cable, then hold the Power button on the TV as you plug it into the mains. You should get 2 seconds of backlight, then they go off. Can be repeated ad nauseum . May give you a chance to spot any bad LED strip.
