The short answer is no - because of the power supply. The Bravia is 220-240V 50hz, the USA is 110-120V 60hz. You can get around the voltage easily enough with a transformer, the 50/60hz is a much more expensive option to get around. I looked into it several times, both when staying in LA for a year and for Americans moving here, and it was not worth the cost.
The Bravia does support NTSC 3.58 and 4.43 replay, but the tuner does not. You can get around that, as I did, by buying VCR, PVR or a cable box to plug into the HDMI or Component inputs and using that as the receiver.
But, I am afraid, the power problem makes that all irrelevant.
