Convergence problem for Samsung HCN5527W

My blue color is off and both "perfect focus" have been unsuccessful in fixing the problem.  At least I think it's not.  Wen in manual, the +\- and up/down did not seem to move anything but just moved me from one set of the cross hairs to another.  Am I supposed to use other keys once I get on the cross hairs?  On perfect focus it gets through green and red but on blue it just starts over and over (37% point)  The blue has a wiggle in its lines.

 

any suggestions or diagnostic help is appreciated.
