The word you're looking for is "Convergence", not Conversion. Those LCD panels are fixed in place at the factory and are not adjustable. Even if it was adjustable, you would have to have the special harness and jigs and the alignment would be done while the projector is on. It would appear that either it's been dropped or it was out of convergence just a fraction of a pixel (which is normal) and someone mucked about inside and made things worse. Sorry, you're stuck.
