The green convergence is out of line

This happens if you move the TV or if it is bumped for some reason. Using the remote and the onscreen menu, there should be an advanced Video setup or config. In there is the convergence tool that when selected displays a pattern that is projected on the screen and you align the color together. Try to only use the colors that are visibly off. Do not attempt to line up the image to be centered on the screen, that is not what this tool is for. It's for lining the colors up with each other. That should do it. If you cannot correct it like this, then there is a good chance that the convergence chip might be giving you a hint of it's demise.
