If the convergence is off more than 1/2 inch or so you can't adjust. you have a failure of hardware. most likely the output IC. This set has 2 outputs for convergence. Each output contains 3 circuits, Six circuits altogether 2 red ,2 blue and 2 green. The normal customer adjustment will only alow adjustment of blue and red. They should be converged onto the green. There is a much more complex adjustment in the service mode for Geometry and convergence. These adjustments are only needed when you replace a failed componnent like the output ic. These ICs have been upgraded several times since the production of this set. The latest and most powerfull version is STK394-160. If feel up to it I suggest changing both outputs and the corresponding output resistors. Then do a complete geometry and convergence alignment.

Convergence Problem and Contrast Adjustment


Have you checked all of the resistors inthe convergence circuit as well? If not, check them for the correct impedance.. Remember, you have to pull one side of the resistor out of circuit to measure it correctly. 
If all of the resistors are good, then you have to do a coarse convergence adjustment on the set through the service menu.. if you need the service manual for the convergence directions, I have one uploaded in the technicians corner of techlore.com

HC R4755w Convergence adjustment


from the symptoms you describe it would apear that maybe one of your amps might be bad... However since you can move it one way then it might be a resistor bad. in convergence cuircit that would be my first choice.
