more than likely the tv speaker output will not have enough voltage to power the speakers, so you'd probably need a power amp in between them.
to test you just need to find what type of sound output connections are on the tv (like strollin said.) then buy that type of plug and connect it to one end of some speaker wire and the other bare end to the speaker connection points,
because of the way speakers work it really doesn't matter which way round you connect the wires to the plug type, + doesn't need to go to + and - doesn't need to go to - (preferable but not essential.)
also there is no voltage coming from the speakers so i doubt there is any possibility of blowing something in the tv.
i'd guess the tv uses the usual sound output connection that needs this type of plug. :- http://www.maplin.co...lug-black-fj89w
like i first said tho i seriously doubt the tv would be able to power the speakers with any type of sound output worth listening to without some type of amp in between the tv socket and the speaker wires.
you can do a quick test of the speakers using a 9 volt battery, just connect each wire to a terminal and you should hear a click.
here's a video showing what i mean.
