Look Keo Tension Adjustment not working

I am having trouble with adjusting the tension setting on one of my Look Keo pedals (if I remember rightly they are Carbon Max 2). The little hex screw on one of the pedals turns freely and gives a little click as it rotates. The other one just turns a fraction in each direction, but no further. I have had a look at the underneath of the pedal and I can see the 'barrel' turning as I turn the hex screw, but it turns just a fraction and then stops against the ends of the spring mechanism (it's difficult to describe unless you actually are looking at it).

They are only just over a year old. Has anyone had similar problems or have any suggestions as to how to fix this?
