i also think we are talking about a different kind of banding.
My problems with the 65HX92(5)9 were the same as described by honda steffen, always with moving camera on plain colour-fields.
Two bands, one left- and one right on the screen were always visible.
I checked other 65's in the shops and they all had the same problem with bands at exactly the same spot.
Is the big screen the problem ? No because the even bigger Sharps were band free.
The 70 inch full led sharp had its own problems with moving camera on plain collour-fields, a sort of DSE, spots moving along with the camera movement.
Oddly, the sharps with side leds, were better in that aspect.
The best i have seen was the Sharp 80 inch 635(?) which was full led, but it had no 3D and the screen was to big.
(We can not get the elite in Europe).
So, new 65 owners, please let us no if the problem is solved.
As you can see, English is not my native language, sorry.
