Just wanted to post my feedback from the 65" set. I've had three delivered so far in quite the horror run.
1) Screen completely smashed
2) Banding and a dead pixel. Also a sizeable mark under the screen which couldn't be removed.
3) A massive green blob on the screen against black. One of the weirdest defects I've ever seen. I saw a few mentions of green blobs in this thread and sure enough this one has it. Also has bad light bleed at the top edge.
So needless to say the quality control is woeful on this one. Apparently there have been record numbers of returns on this set and I mentioned earlier that there is a full investigation into the quality control going on (in Australia at least).
Other observations. 3d cross-talk is seriously bad. Worst 3d TV I've owned.
The disappointing thing is that the TV is just so good, if it didn't have these faults I'd be so happy. The way the local dimming works for an edge lit is crazy. The up scaler is excellent, from 720p up looks really clear.
I don't think you'll find a set without banding but I've never seen an LED without banding so I don't know how much stock to put in that. I wouldn't say it's worse banding just similar to most other sets. The banding is worse against green (ie World Cup) then it is against white (hockey).
I'm going to keep going. Having owned a full-array 950 1080p set I rate the local dimming on this very high so I'd be inclined to recommend this of the two. I don't think I'll find a set I like more of the current crop. If you don't have a lot of time on your hands and a store with a good replacement policy, I would avoid this think like the plague.
