Plasma Problem
I have an LG UN60D8000 and it has started to shut the screen off (the power and green light stays on) after about 10 minutes (cutting off the top 80% of the screen - to black) and then soon going all black, while making powering up and down fan noises. then if you turn it off and back on it will work for less and less time before going to black, unless you let it sit for 20 or so minutes and then it goes back to the 10 or so minutes .... leads me to believe it is something heat related. Please let me know if you have any insight into what the problem may be.
