Samsung 50" plasma, between my wife, son, and my account on destiny that's probably 800 to 1000 hours and no real issue. My account alone is over 650 hours. I bought mine for gaming because of the quality of the picture. I did a roughly 400 hour break in, twice what was recommended to be sure. I do run scrolling every night for 10 minutes when I go to bed. Thankfully the picture is still as amazing as the day I bought it! Hopefully your issue will resolve itself with normal use. In the future if you're going to go with plasma try to get one with a similar feature. For mine specifically I just turn on scrolling and go to bed 10 minutes later the TV shuts itself off. Good luck.
