A:Answer Thank you Chris!
I already have voltage converter which I use in US to get euro-voltage for some of my devices. It works also another way around, so that kind of solves the voltage and plug problem.
We don't have analog broadcasts anymore in Finland, so I need only DVB-C for digital cable broadcasts. OLED55C7P doesn't have that, but I have external recording receiver in Finland so that is covered as well.
My biggest concern is external devices: the DVB-C-receiver and PS3 (used mainly as Blue Ray player). Is there any problems using these external devices (from Finland) with US tv? Both devices would be connected via HDMI.
