3 of them, huh - sounds like you run a sports bar - or you need to tie down the arms on your friends when over to watch the game so they can't throw things at the screen.
You can usually get replacement screens from the manufacturer, of course TV Repair shops can get them (though might not sell direct to you, wanting to do replacement themselves). Also lots of places on web advertising them - from commercial TV parts vendors to eBay, so obviously a variety of credibility levels.
Keep in mind in eash case what the replacement cost is for a comparablenew TV, because in many cases a screen replacement (especially with freight included) costs more than getting a whole new TV.
