Hello guys, I own my PS51D550 since 2 weeks here in France, I was afraid about this pops but...
I haven't a single one and trust me I am very " maniac " about PQ.
My set is from Hungary, August 2011, firmware 1024 onboard.
There's also a second sticker on the back, not the one with the serial number on which is written " version 2 ".
There's no visual external differences on my set, so why version 2 ? Hardware differences ?
I can't have the 10 points calibration on this one, changing model number does nothing special.
