Well, I have never tried a TV before. I have done it with laptops, tablets, telephones, CPU, PlayStation 1, 2, and 3, and never had a problem with the 240 of Lima, Peru.
TV it might be too risky, I think. My best response is call Samsung but not the one in Argentina (Argentina's Samsung Store). Call Samsung (US office or international customer service number) and check directly with them.
I mean, laptops can be very expensive (like the one we have and took it) and we could have burned it in Lima. Inside the box it might say if it is save or not but I suggest call Samsung. I say this because I think if you are taking a TV to Argentina, it must be a complete or top of the line TV. I think, it would be a one that is very expensive over there or very hard to find. Call, it is a burn-free option.
