Sony KP-57HW40 Convergence Problem

My RPTV is about 8 years old.  It recently started having a convergence problem.  Using a repair kit, I have replaced both chips.  I believe my sodering is in good shape, but it has not fixed the problem.  I have checked the circuits on the pico fuses and resistors on both the D and G boards.  They all checked out.  Once I have everything back together and turn the tv on, using both the flash focus button and/or the remote I can not get the picture to change any at all.  I also can not tell any difference in the temperature of the chips after the tv has been on for a while.  

 I am not a technician and am not 100% sure I know what I'm doing.  Any suggestions?
