So, got a60" plasma tv. Had it a couple years now, and it's developed a problem lately. The middle of the screen goes from fine to kinda half faded, splotchy, just crappy. Also, when is actually flickering it will burn in in like a second, but isn't permanent. Tends to happen on brighter colors. Any thoughts on what it might be/possible fixes would be greatly appreciated. I can try to get the problem on camera, but that doesn't work well. (And yes, i know plasmas aren't the best for gaming, but this one's done just fine so far and i don't have money for a new one)
