Hello, I purchased this TV (LN40A650) in 2008, and it's been working fine until recently. I haven't been able to find anyone reporting a similar problem, but here is the description. - I'll notice a weird glitch, like a small square of static suddenly appearing in the middle of the screen (otherwise, the image looks fine), and then the TV flickering for a second, then a thin band appearing at the very top of my screen, directly beneath the bezel. - This usually happens about 20 mins or so after the TV is first turned on. - That line/band at the top of the screen goes away when I turn the TV off and then on again.... I haven't seen the problem reoccur after turning the TV off and on again once the issues appear. It only reoccurs the next day, when I turn the TV on for the first time in the day. What could this be?
