hi chaps happy new year, went to look at this lg 47l6453db dark picture. shine a torch on the screen,i can see a good image, clicked on the picture setting backlight is zero colour zero brightness zero i've turned them up no joy, if you turn the tv on and off it might come on, apparently they connected wii the picture went off, not sure whats happening at the minute , thanks for your time
