sounds like you don't have the receiver (or all-in-1 unit including dvd player, not just the dvd player. Speakers do not run off of dvd players. If you just have the speakers you will have to but a receiver/amplifier to drive them. Since lg speakers aren't very good your probably better off starting from scratch and buying a basic home theater system. As others suggested, you might find a matching all-in-1 for those speakers on ebay.
