Hi, I'm owner of a X70.
My device has no CA/convergence issues I could talk about, no pixel fault, no perceptible clouding/shading, whole picture quality is absolutly sharp and clear ... short - at all I'm really excited!
But there is one issue I'm wondering and would ask other Xyy/RSyy owners about (maybe they are also affected):
In high lamp mode, on the screen I can observe a not 100% stable (bulb?) brightness within the range of a displayed ~30 ... 60 IRE AVSHD full window test pattern (CalMAN/HCFR section doesn't matter).
There's a very, very slight pulsing up of brightness, almost cyclic for ~ 1Hz. It's absolutly not perceptible in normal lamp mode, and it's independent regarding the - via HDMI direct connected - player (PS3 and cambridge 751 does it as well).
Cause it was also with the first X70 I could check some weeks ago, now I guess it's a system behaviour. But to really go sure, it would be great, if anyone else could take a closer look about that in high lamp mode next time he's displaying this IRE full windows test patterns.
(This slightly brightness pulsing is already perceptible, if I focus my eyes for some seconds upon the menu background of the AVSHD CalMAN full windows submenu)
Finally I have to say, it's not perceptible while watching movies - only in static pictures of that kind. I just only can hope, it won't get more intense after several hundred hours of lamp runtime ...
