Exactly same as mine. Problem is still existing.

don't think theres a simple fix, going to need to pull the back cover off if you want to troubleshoot it, take some good clear straight on pictures of each board and one of the whole back, as to see how everything is connected, use the go advanced button to upload. It is kind of strange how it moves around, seems like a backlight issue, wonder if it's to do with the connections of the strips or such. They can start getting intermittent and act up, ever see one of those youtube videos where they whack the tv with a bat and it works? NEVER do that by the way, you can tap here and there but don't whack.
