This looks to be a driver board on the LCD. But no tech I know would diagnose this online or quote how much. There is only one panel but again, a tech should take a look.
I recently bought a 46 inch eh6000 and I am noticing two thin vertical lines whenever bright or light colors (for example sky in the background) are displayed on the screen. When it shows, it's as if it is the seem between two panels. The contrast between the "two panels" are visibly different.
