Sony KP-43HT20 Convergence Problem

My Sony KP-43HT20 projection TV was very good. I accidentally pushed Flash Focus button and it lose the convergence. I pushed Flash Focus button again many times. It could almost convergent the red and green colors, but couldn’t move the blue color. The blue tube couldn’t project the parallel lines. The blue curves up and down on the left side of the screen and the pictures are blurred, Could someone advise me how to fix the convergence problem? Thanks.
