Does the TV have a SCART connector at the rear? It is a long socket with 20 flat contacts. If so, this will have audio out. You can get a suitable SCART cable with audio connectors at most TV/HiFi shops.
However, regardless of what audio out connectors are on your TV, the signal level won't be sufficient to drive speakers directly. You will need either a separate amplifier and speakers or combined amplifier/speakers (the type normally used for iPods, MP3 players, etc.).
