I fell asleep with a DVD playing and when I woke up the DVD menu had burnt into the screen. I used the screen burn protection built in to the TV. It seemed to clear up but now where the screen was burnt are blue blotches that come and go. When I watch SD content within minutes two thirds of my screen is covered in blue blotches. With HD it doesn't happen as often or as quickly. A friend suggested I should stop watching the TV for several months and it will fix itself. Is that possible? What should I do?
