Hello I also have a similar problem.
repair ticket # 4113851260
PN59D8000FFXZA Samsung 2011 Plasma Currently under review with Samsung. I sure hope they make good on their warranty. I love Samsung and I have so many of their products. My screen cracked after a small pop noise as my wife reported and then would not turn on.
Dont be a Samsung hater though they make many good products. I am sure they will make good on this issue also.
Any comments are appreciated.
