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.
Testimonial: "You are an expert? OK.. You would know I can get a motherboard for $20-$30. Why would you not offer that advice? Do you work for Samsung? Thank you"
playing with remote, I put it into 3d mode. Then back out of 3d mode. now backlights are working. YA! Cost? $0
Whether the MB for that particular TV model is available or not is something I dont know. So, I cannot comment on that. You may try the settings of the TV using your remote and increase the brightness level and reduce the blackness level. If you wish.
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.

You didn't say if you are receiving an off air picture or cable or satellite. The reason the commercials look good is because the local station (or source) transmits them "in the clear", that is, without any enhancements to the video signal. Network programing or local newscasts are sent through a device which inserts a reference signal in what's called the "vertical interval". You may have seen this as a series of flashing dots or pulses at the very top of the picture. There's a lot of information packed into the VITS (Vertcal Interval Test Signal). One of the lines contains a reference pulse for video which is set at a certain level. Your TV sees that level and automatically adjusts its circuitry accordingly. What I suspect is that your set is out of calibration and is pushing down the video signal because it is not "seeing" the level properly. A video alignment should correct this and can be done by a good repair facility. Hope this helps.

Yes, they dim as they age, and you've done well to get 3 years out of one.
Projection TV makers charge an arm and a leg for their replacement
lamps. They make it easy to do but as a result the custom lamp
assy is expensive. The trick is to just buy the bulb for your
model TV from any number of us aftermarket sources at a fraction of the
lamp price and install it in the old lamp yourself. really
easy.

I too have the same problem with the same monitor.. tv looks great OSD looks great.. pc is dim.. This has nothing to do with the inverter board or the backlight.. I believe that there is an issue with the components that render the Computer video.
