Hello,
I have a picture of the screen here: http://www.austinthirdgen.org/gallery/d/9551-2/TVconvergence.jpg
The TV allows only blue and red adjustments, not green. So I can't adjust this.
Is this a problem with the convergence amplifier circuits?
Thank you very much in advance.

.. could you please state the occurence? is it after you have tryed to adjust something? or is it the was moved several times?
..hi again.. the funny thing about troubleshooting is that sometimes we dig deep enough aiming to resolve what we should.
if your unit was set for how many years now it might be a cold solder connections mainly in its printed circuit board in convergence and focusing circuitry. speaking of picture alignment likely in color are greatly affected by magnetic fields generated from focusing rings and or coils thus these coils could loose power to produce the necessary field. also if you can find the RGB color rays pls do check that all three is running fine. hav a nice day for you..
..also pls not try adjust internal settings from trimmers, coils and the like just try to look for cold solder first.. good luck..

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com
Common Problem #1) Convergence has gone out
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then yourconvergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

This TV belongs to my in-laws. The TV has not moved in years. All of a sudden, they said the picture looked "funny". I displayed the alignment grid and that's what it looked like (in the picture).
Thank you very much.

As I originally suspected based on the symptoms (and other posts on this website), the convergence amplifiers were bad. So after 20 minutes, the TV is back up and running.
A simple Yes/No answer would have helped a little more.
Thanks for trying.
