I have gone through the standard convergence alignment procedures offered in the menu of the TV. It does not seem to fix the red and blue convergence in one small area of the sceen. The middle of the screen on the far left is way out and it is very noticable when there is writing or lettering on the screen. I had a tech out 2-3 years ago to fix the same problem, and he did. When he did, he simply used the remote to get the TV into a "service mode" with a much more specific adjustment pattern( more than the 9 point offered in the menu). Can I access this mode myself? It looked very easy I just don't have the book/manual that told the tech how to do it. Can I buy that manual?
IF you still want to know how to enter service menu to set convergence i know how.
If the mis-convergence is only noticable on the left center and the top and bottom left side of the screen is good, then it sounds more like a pincushion distortion problem rather than a convergence one. Otherwise, you could have a bad pair of convergence IC's or capacitors / solder connection problems. I would doubt that adjusting the service menu would correct this problem, and you could make it much worse by trying. Better have a technican work on it if the picture quality is still good otherwise.
SOURCE: Red convergence is out of alignment
I actually disagree with that information. IF you can move both horizontally and vertically the blue and red convergence then the ic's are fine.

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.
