Probably not, but you never know.
It will definitely not play them using the composite video or s-video inputs, but it might on the component or hdmi inputs. There wasn't any detail in the user's manual that said yes or no, but the mains voltage is specified as 110-120VAC 50/60Hz, so you never know.
But I has a similar question when I was interested in the Sharp Aquos TV, and as nobody could tell me, I ended up testing it at a dealer with both a PAL VCR and a PAL DVD player. Interestingly, the 30" and 37" models would not play PAL, but a smaller one (I forget which) did!
But that's Sharp and this is Samsung, which may be significant, since my Samsung DVD player (manufactured for and sold in the US) plays PAL DVDs (as long as the region code is 0 or 1, of course).
So, again, probably not, but short of someone who as actually tried it (or a call or email to Samsung support), there's no way to know for sure.
