I have a series 6 oled 65 inch it is 1.5 years old. It has experienced burn in from the news baners that CBS uses. This is true even though I simply watch the evening news. That is bad enough but now it has a growing green patch that is not burn in. See the lower right quadrant of the screen near the tail of the y. This is a know problem with series 6 pannels. I am 6 month out of warranty so lg say too bad. In short, lg manufactured a faulty pannel, which it has since replaced, but won't aknowledge or stand by its customers. $3,500 wasted.
