I have a 3 year old Samsung LED tv. it went very dark all the sudden but still had a picture
I turned the backlite setting all the way down and it brightened up a bit. if I go to turn the backlights back up 2 notches it will start to brighten up more but then on 4th notch it will go dim again.

A Bad chip on the mother board. Not worth fixing. Too expensive.
I had a similar problem on my Samsung (about 3 years old). The Samsung repairman changed the motherboard and charged me around $150 for it. But, the picture quality has never been good since then. I am going to gift it to someone and buy a new one.
was playing with remote. switched it to 3D mode then back out of 3D mode. Now tv backlights work as normal.
