Sounds like one of the gears inside the cluster is either broken or stuck. I'd say swap the whole cluster if you have an analogue cluster.

Hmm, I once got out some of the gears on my speedo it's wasn't as hard as I thought it would be...

Just take the cluster out of the car sit down somewhere quiet, then take of the plexiglass panel of the front. After this take the screws out of the back of the speedo and you can have the speedo removed from the cluster...

Shouldn't be hard to diagnose the fault after that. Have a look at the "cylindrical sprocket" (don't know how to call it but it's a "wormwiel" in dutch).
