erm could you try to be more precise with the problem you are having. Is it audio, no video for TV and everything or just like with a dvd player?
Er.. i setted up my new tv and nothing's wrong with it. is ur tv damaged? I'll check on my tv now and see if that happens to mine...
i think there is no light to power the picture or something like that. I took it apart and i was llike WHOA, a TV!
dont open the tv and try to fix it yourself if u dont know how cuz i hear there's some bolt or something that might shock and fry u. anyways maybe theres a loose cable.
lol Yeah don't try and open the tv bring it back to the shops if it cant work. Well check all cables and that first
