I doubt its the circulating pump if the others are getting hot, unless they are the last on the loop. Even so, if you turned off the other rads and it only gets warm then you have a problem.

Its either airlocked or just plain blocked. When you say bleeding has not worked, what does this mean? I assume there is no air left in the rad.

Check both the inlet and outlet of the rad. Maybe someone messed around with it. Make sure both arre fully open and all other rads are off and try heating them again. If they still dont heat then may be full crap. How old are they? When they do heat, do they remain cold or colder in the middle at the bottom - this is a sure sign that the rad is full of crud.
