My elderly father noticed a difference between our two Samsung TVs. I realised that the older (42 in model) was much brighter. The menus on both are similar BUT importantly the older model has adjsutable backlight. The 55 in backight is greyed out in all sources. I've tried resetting to factory settings and resetting the picture but still the backlight is greyed out. Any information appreciated.
