Not familiar with this unit, so if someone is, they can override these general comments:
1) have you done convergence before? If so, I would open it up and see if there are any adjustments on the neck that aren't firmly glued in place.
2) errors in one quarter of the screen are the least likely to be fixed by adjustment - you can end up just chasing the error from one corner to another - but you might experiment placing small magnets on the bell of the tube
