Well I picked up my replacement TX-47 on Tues and am happy to say the void in the entertainment center is once again filled with beautiful images from the Westy! I am blown away with how smooth the replacement process went - I had the set back to BB within hours of it going down and they had my replacement in the store in 4 days.
I gotta say even though I have always loathed BB, I am very glad I purchased this set from them... I'd be crying if I had to mail this thing in to an online store.
A couple of notes about my new unit:
1) Exact same build date - Apr 13. Does anyone have a different date?
2) 6 dead pixels! My last unit had none
However, you need to stick your face right up to the screen to notice, so I really don't care.
3) Banding is LESS noticeable! I mentioned before that I can see banding during one particular screen while playing Ridge Racer on the PS3. Well, it is still there but it is much less noticeable. I have never seen it during normal TV viewing, and even on the one screen where I can see it you have to look really close so I am not concerned about it.
Given my experiences with 2 different TX-47s, and looking at the animation that PanzerBoxb just posted, it is obvious that not all of these sets are created equal.
PanzerBoxb - Thanks for that excellent animation - now I truly understand what mura/clouding is. WOW - your set has it bad! Neither of the 2 that I have played with have anything close to that! I can see it a little on the bottom left of the screen but only if the backlight is turned way up.
I am posting some pictures including a shot where you can see the banding that I am talking about.
