Sorry, your post looked like an ad. So I deleted it. But I can answer it here.
If that link to that shop advertises the Samsung 55B6000 multi-system TV as working on many voltages (just like any laptop adaptor does) and many systems (like PAL) there is no reason to not believe them.
But I see that TV offered in many webshops. So select the one you trust most, has good reviews, has a good price and can answer all your questions.
The most important thing, if you buy it in the USA and are going to use it elsewhere, is that it has an international warranty. You don't like to send it back to the USA if somethis is amiss in the first 2 years.
