There is a chance it may not be able to receive freeview over here of the normal Czech broadcasts aren't of the same standard and frequency as the UK but many manufacturers make them universal and just ask what country you're in. A chance it'll work and a chance it won't.
Also many TV's now use a special connector on the back of the TV. My LG has a specific one, unique to LG I believe. You'd need to source a power lead and check the TV supports 240V input too otherwise you could kill it as soon as you plug it in.
