Summary: I bought my 43inch in August of 2011. Picture great, sound great, really liked the tv. Now 15 months later I am watching TV and the picture just goes out, black screen. I go to hit the power button to turn it back on and nothing. So I unplug the unit and let it sit for a minute, plug it back in and you can hear clicking noises and the red light flashes, but still no picture. I did some research and found that this problem has occured in other Samsung brands.
