sanwa Exzes X Steering issue

[qatmix]

Hi All

A friend has a Sanwa Exzes X that he recently purchased. However it has a problem that the steering seems to just be stuck to the left. If we try to go into the calibration menu it says system error.

The stick does register moving towards the right (A little), but with the sticks in neutral the unit says it is 155(ish) units to the left. When moved to the right it goes down to about 110..

Any idea what this could be? or has he been unlucky with a duff handset?

Thanks
