I have a 46" Series 5 Samsung HDTV - http://www.samsung.com/nz/consumer/tv-audio-video/television/archive/LA46A550P1RXRD/index.idx?pagetype=prd_detail
I bought it second hand and the buttons on the control panel of the TV, bottom right of the bezel, do not light up making it almost impossible to see them. My father's series 9 buttons light up, are mine supposed to? Or is that just how it is?
